#5. San Andreas
Geologic Sin Meter: Apocalyptic
Though this meter is obviously subjective and somewhat vague and arbitrary, it does bear some explaining. Basically, the more hyperbole in the rating, the more egregious the sins against science. Pretty simple I suppose. The Apocalyptic sin meter rating for this movie indicates that there are numerous accounts of phony science and, in many cases, flat-out nonsense. Now let’s get to it.
Here is how I will break down each of these movies: I will begin by putting forth the geology that is addressed in the movie and give some general background. Then, I will address each geologic occurence/question/theory/etc. in each of these movies and explain/discredit/endorse its validity. I may use some terminology that is not layman, but I will do my best to keep it relatively simple.
The Background:
This movie is based on the idea that a heretofore unseen earthquake of magnitude 9.6 (Richter Scale) occurs along the famous San Andreas Fault in California. The fault and its system at-large is a strike-slip system, meaning that its motion is lateral as oppose to up and down that you might find in a subduction zone. It runs roughly from the Gulf of California and the Baja Peninsula to its end in the ocean north of San Francisco about 0.5 miles offshore (figure 1).

It has been responsible for several large earthquakes, including a 9.1M that struck San Francisco in 1906 that resulted in the near total destruction of the largely wood-built city. It also famously slipped during game 3 of the 1989 World Series between the A’s and Giants at a 7.5M, resulting in the structural failure of several bridges in the Bay Area, as well as billions of dollars in damage.
Faults occur along weakness in the lithosphere (crust) that allows the crust to move and slide along planes. Faults are particularly likely to exist where tectonic plates are converging, diverging, or transforming. Since the Earth’s tectonic plates are in constant motion, thousands of earthquakes occur each day all over the world, though the vast, vast majority are too small to detect by anything but seismic equipment.
What is the San Andreas Fault?
The San Andreas fault system is the child of the North American and Pacific tectonic plates that are moving in opposition to one another along their boundaries in the southern California region (figure 2).
|
Figure 2: courtesy livescience.com |
This motion causes the plates to grind against one another. Pressure builds at certain points along the system and when the point can no longer withstand the pressure, it gives causing energy to be released radiating in concentric circles from the point. These waves of energy are what cause earthquakes, and are called S-waves and P-waves. The P, or body waves, arrive first and are the marker for seismographs. S-waves arrive shortly thereafter, and cause the ground to shake perpendicular to the motion of the wave.
The largest earthquake to ever be recorded was a 9.5M off the coast of Chile in 1960 (this fact is given to the audience in the movie). This occurred in a subduction zone, where the Pacific plate is “ducking under” the South American plate causing pressure to build. These zones can cause particularly catastrophic earthquakes. Though the San Andreas has produced a 9.1M, it is theorized that it is unlikely that a 9.5M or greater could occur.
A sidenote here: The Moment Magnitude Scale, the measure of the energy released by earthquakes, is base 30 logarithmic, meaning that each division is 30 times more powerful than the last. For reference, a 9.5M earthquake is 30 times more powerful than a 9.49M earthquake. This means that the 9.5M recorded in Chile was 1200 times more powerful than the largest quake ever recorded in the San Andreas system.
The Geology Sin Counter QnA Session:
Could a 9.6M earthquake occur along the San Andreas fault system?
The short answer is theoretically yes, but it has never been recorded by seismographs, nor in the rock record where geologists can study fault zones and rocks deformed by earthquakes to measure the stress placed on the rock. This does not mean it could never happen, but most models predict that the most powerful earthquake the San Andreas system could produce is roughly a 9.2M, which is still cataclysmic, but not nearly as devastating as the earthquake in the movie.
Could a 7.5M earthquake occur at Hoover Dam?
In the movie, the precursor to “the big one” comes in the form of an earthquake that destroys the Hoover Dam, quite spectacularly I might add. The short answer here, is likely no. Though there are faults in the area of the dam, none of them has the capacity to build and release the energy for a 7.5M EQ. Rest easy dam-goers, you should be okay. In addition, any structural engineer will tell you that the Dam would not buckle so easily as it did in the movie should such an event occur.
Can seismologists predict earthquakes with 100% certainty?
The answer here: In short, hell no. In the movie, Paul Giamatti’s character has created software that uses seismic pulses to predict with 100% analytical certainty that an earthquake will occur, and even goes so far as to claim that they can predict the location of the epicenter, and the magnitude on the impending quake.
Frankly, this notion is laughable. Any geologist who tells you they can predict earthquakes or volcanic eruptions with any absolute certainty is selling snake oil. The Earth is a dynamic living thing, and predicting its actions with any degree of certainty is like predicting what a teenager might do while driving a vehicle. You can monitor, theorize, gather data, poke, prod, bother, and vex, but you cannot ultimately say with any absolute surety what is going to happen once they get behind the wheel.
Would a quake along the San Andreas open up long canyons, exposing the fault line?
Once again, in short, not a chance. This goes back to the type of fault the San Andreas is, a strike-slip. This motion is lateral. For a canyon to open, such as one in the movie, the Pacific and North American plates would have to suddenly begin to shift away from each other, resulting in a divergent plate boundary, that may then open up a gaping chasm in the Earth. It is a cool visual effect in the movie, but violates fundamental geologic laws of motion.
A quake of magnitude 9.5 would certainly leave its scars on the surface, just not a gaping canyon.
Would skyscrapers liquefy in the presence of a quake of this magnitude?
Although the destruction would be massive, and the damage horrific, it is highly unlikely that structures such as the TransAmerica Tower would suffer the fate they did in the movie. In fact, many of the skyscrapers in San Francisco may be some of the safest places you could be in a quake. They are engineered specifically to “sway” with the motion of the quake. For a moment. imagine San Francisco is built of Jell-O on a table. Shake the table as violently as you can, and it is likely that the Jell-O, though it will show some signs of damage, will still be standing. These are the same principles that went into the engineering of most of the modern structures in the city.
In short, no, this would not happen.
And the $1,000,000,000 question: Would this earthquake result in a 100m-high tsunami that eats the city?
Once again, my answer here is short and sweet: Absolutely not a chance.
The San Andreas, in addition to being strike-slip which would not displace the amount of water that an earthquake in a subduction zone would (think Sumatra 2004—>That was a 9.1M on a convergent boundary), it is also 95% terrestrial, meaning that even if it could displace that amount of water, there is no water to displace. Near San Francisco, the fault briefly leaves land and goes into the sea, but even the most catastrophic quake would result in waves only 2-3m in height, a far cry from the monster wave that was eating oil tankers in the movie.
The Final Word:
So there we have it folks: the Geologic Sin Meter broke during the making of this movie. Still, this is actually a good movie, with a solid performance from The Rock, as well as Australian beauty Alexandra Daddario and Oscar-Winner Paul Giamatti. The entertainment factor is high, and the special effects are excellent, even breathtaking. If your goal is pure entertainment, which is typically mine when I watch a movie like this, then you will have come to the right place. All other things being equal, I will watch this movie and enjoy it, though I will be forced to bury and hide my scientific BS detector. Enjoy it folks!

#1: Tremors
Look Mom, weird prehistoric underground monsters!
Geologic Sin Meter: Graboid-Tastic
Geologically speaking, this classic goofball sci-fi flick is nearly devoid of sins, although there is a major biological question that is presented. Though science is really not the focal point of the movie, geology plays a significant role. Characters “hide” using rocks, the geology of the area is discussed as a means of escaping the monsters, the fossil record is discussed, and there is even quite a bit of geology lingo such as “pleistocene alluvium” and “precambrian”. Many shots in the movie are of beautiful rock formations and the gorgeous basin and range topography of southern Nevada. As a bonus, a large cliffed-out canyon is the means by which the last “Graboid” is dispatched of. Geology!
Movie Background:
Welcome to Perfection Valley, Nevada. Population: 14. Then 13. Then 12. Then 10. Then some unfortunate road workers. Val (Kevin Bacon) and Earl (Fred Ward) are local handymen trying to change their dead-end existences by leaving Perfection forever, but they are compelled to stay when the townsfolk begin to disappear under strange circumstances.
Rhonda (Finn Carter) is a PhD candidate seismologist, studying the area with seismographs trying to get a beat on seismic activity. Together, they discover and then outrun underground worm-monsters that devour everything in their path, and have to save the people of Perfection from a gruesome demise.
Geologic Background:
There are a few geologic angles to this movie. The science of seismology, the geologic province in which these monsters are found, as well as paleontology and the fossil record.
Seismology is officially defined by Webster’s as “the study of earthquakes and the propagation of seismic waves through the ground”. These scientists are commonly referred to as geophysicists, and are somewhat loosely related to geologists who study physical rocks and their deposition.
Seismologists or geophysicists are more interested in using seismic waves to infer subterranean geology, and their work is the basis on which our theories about the interior of the Earth (the mantle and core) are derived.
They are also interested in monitoring seismic activity in the subsurface to make inferences and predictions about earthquakes and earthquakes hazards/risks. Nearly all seismologists and/or geophysicists have geology backgrounds, but chose to do their graduate work in the more specialized field.

In the movie Rhonda LeBeck (Finn Carter) is a graduate student from MSU (?) as denoted by the initials on her seismic equipment. Although it is unclear exactly what she is studying, she is using the seismographs to gather information about seismic activity in the area.
A seismograph is a tool used by seismologists to gather information about energy and motion in the Earth, specifically during earthquake events. They are very useful in determining the force and duration of seismic events, and play the role in this movie of alerting our heroes that a Graboid is near (Yay!).
The geological province in which the movie is set is known as the Basin and Range. It extends west, south, and southwest from the Colorado Plateau, essentially from northern Arizona and New Mexico south well into Mexico, and west from Las Vegas to the Sierra Nevada.
|

The province is characterized quite literally by low basins in which sediment accumulates, and northwest-southeast trending mountain ranges that are bound by normal faults. It is an area of extensional-type tectonics, meaning that the crust is being pulled apart or rifting.
The prevailing theory for how the Basin and Range has come to be is related to the Laramide Orogeny that built the Rocky Mountains. Long ago (80-55Ma), the Farallon tectonic plate subducted the North American plate, building the Rockies.
|

At some point between 5-15Ma, a piece of the Farallon plate snapped off, and is currently “floating” in the mantle under the modern-day Colorado Plateau as suggested by current geophysical research. As a result of this “floating”, the western portion of the North American continent is “sliding” westward, creating this large area of extensional tectonics. In fact, geologic research indicates that San Francisco, CA was once located near what is now Flagstaff, AZ prior to the extension taking place.

Paleontology and the fossil record also play a critical role, as it is one of the central question of this film, “where did these things come from?” There is a debate amongst the three central characters as to the answer of this question, and one of the theories put forth is that they pre-date the fossil record.
The fossil record goes back roughly 3.6 Billion years, beginning with an animal known as the Stromatolite, which essentially is algae. Life on Earth existed as single-celled organisms for hundreds of millions of years until the “Cambrian Explosion”, wherein many vertebrate fossils begin to appear and there is a proliferation of diversity in life.
From there life moved out of the seas and onto land, and evolved into humans and all the variation of creatures that we see today. This is obviously an extremely simplistic and stunted version of this story, but we only have so much space here.
Where do Graboids fit into this story, you may ask? Well, that answer is the main part of our Sin QnA.
Geologic Sin QnA:
Could an animal like this really go unnoticed for that long?
|
A Graboid in all its glory (courtesy pophorror.com) |
Herein lies the main geologic, or more aptly biologic sin of this movie. In terms of evolutionary biology and ecology, the existence of the Graboid is a near impossibility. How could an animal this large and voracious have possibly gone undiscovered, or have even evolved? Well friends, on both counts it almost certainly could not have.
Strip away everything else for a moment, and it still seems highly unlikely. Never mind that these animals have nothing to move their giant bodies but small spikes, and that they only exist just below the ground. Never mind that to have evolved into this form would have taken tens, if not hundreds of millions of years and lots and lots of large food or an extremely efficient metabolism. Never mind that, despite feeding on livestock and humans, nobody has ever seen them.
Take all of that away, and what we still see is a creature that, in its current environment of the Perfection Valley, is all but locked in by hard-rock mountains on each side, large, sheer-cliffed canyons on the other side, and a serious lack of a reliable food source even if they did escape the valley. The Mojave desert is a wild and inhospitable place, particularly for large predators like a Graboid. Maybe the occasional Bighorn Sheep would do the trick?
Debating anything beyond simply the vacuum existence of these creatures is pointless, and the deeper you delve the more reason you find that, scientifically speaking, it is a near biological and evolutionary impossibility for these creatures to exist in this state, essentially crushing the main attraction of this movie. Bummer, because it would be super cool to see a Graboid.
However, it does still leave the possibility that they are extra-terrestrial. But…..They could not have survived the impact of an asteroid that would have deposited them, nor do they seem capable of constructing and piloting their own ship. Maybe they were placed here by more sophisticated aliens or even human beings?
The placement theory could be interesting, as it was suggested in the movie. Val surmises that they are an invention of the Russians. This suggestion, made during the waning years of the Cold War, is absolutely possible, maybe more so than any other legitimate suggestion. I
t is possible that they were created in a Soviet genetic laboratory, deposited as babies in the remote areas of the Mojave Desert, and survived and grew as they fed on the local cuisine of coyotes, bighorns, the occasional lost hiker, and eventually the people of Perfection. Was it the intention of the Soviets to have these animals infiltrate a large city like Las Vegas or Los Angeles and create mass panic and confusion, thereby giving the Soviets an opportunity to seize the moment and overtake our government? Seems likely :).
Is the geologic terminology used correctly?
Yes. A few geologic lingo drops are to be found, including a reference to “pleistocene alluvium” and “precambrian”, as well as discussions of topography, which is dictated by geology. Pleistocene alluvium, or more simply referred to as “dirt” by Rhonda to her slack-jawed audience, is exactly what collects in the basins of the basin and range.
Although is it more commonly referred to as Quaternary alluvium, this is still generally correct. What is the difference? The Pleistocene is an epoch (1.8Ma-10Ka) within the Quaternary era (1.8Ma-present), most precisely the epoch in which the last ice age occurred, ending roughly 10ka ago. We are currently living in the Holocene, which has its beginnings when the ice melted and the glaciers retreated.
|
The groups using geology to their advantage (courtesy pop horror.com) |
When someone is referring to Pleistocene alluvium, they are typically referring to sediment deposited by glaciers. In the basin and range, sediment is deposited in the basins by runoff from the mountains (ranges) following precipitation and mass movement events, and likely not from glaciers (even during the Ice Age). In addition, it would be very difficult, if not impossible to absolutely date this alluvium to the pleistocene era, which is why we geologists generally refer to unconsolidated sediment moved by water as Qal (Quaternary alluvium) on geologic maps.
What possible purpose would a graduate student in seismology serve in this area?
Well, the same purpose that any student of science would serve anywhere: To gather and record data that may be of use to major and groundbreaking scientific research. We all want the glory, and a few of us find it out in the field. More specifically, seismic research in the basin and range is important because it allows us to infer the location of active faults, which is useful in determining earthquake hazards.
Would the groups escape plan really have worked?
In short, yes. The Graboids are very adept at moving through the unconsolidated sediment that fills the basins. Heading for the mountains, and therefore the consolidated and lithified rocks such as granite and metamorphics such as gneiss that are typically found in mountains would have stopped the Graboids dead in their tracks. Geology, as usual, will save the day.
Final Word:
This is one of my, and many of my colleagues’ (hence its #1 ranking) favorite movies. Young Kevin Bacon trying to act cool to get the PhD-candidate seismologist, Fred Ward in a classically serious-yet-goofy role, country star Reba McEntire and Michael Gross as elephant gun-toting survivalists, and enormous, angry, hungry underground monsters that devour whole cars; could a movie possibly have more awesomeness? The correct answer is no.
For a fun fact, the movie was filmed just west of Death Valley in the Owens Fault Zone, and not actually in Nevada. However, these areas are quite similar geologically, topographically, and the scenery is very similar as well, so this is not so much of a sin as much as just the realities of Hollywood and its propensity to film in one place and call it another.
Despite the over-arching assumption the movie makes that these monsters have escaped discovery for thousands of years and have no fossils because they pre-date the fossil record (or something else?), this movie is just simply so fantastically goofball entertainment that it really does not matter. Watch it; laugh, cry, scream, and smile until your jowls hurt, I promise that they will.
May The Goat be always with you

Top 5 Best Bad Geology Movies of All-Time
One of the greatest (and possibly most irritating) pleasures of being a scientist is the plethora of movies that take something minutely theoretically possible, throw it in a pot with pseudo-science, and create a colossal disaster the likes of which the Earth has never seen. Very rarely does any real science make it into these “science-fiction” movies, but that is what makes them both fun and entertaining: the utter lack of reality or science.
Over the past two weeks, we have been gathering votes from our fans on social media naming their favorite geological disaster movies of all time. We have compiled the leading vote getters, so get ready to have your minds blown: Drumroll please…..
(All photos courtesy amazon.com)
#5. San Andreas
Premise: Cal-Tech University seismologists have created a predictive modeling software program for earthquakes that has 100% accuracy. This program predicts that the notorious San Andreas fault, a right-lateral strike-slip fault system on the transform plate boundary of the North American and Pacific plates, is going to rupture with a 9.6-magnitude earthquake.
An S+R helicopter pilot, played by Dwayne “The Rock” Johnson, needs to go through literally hell and high water with his estranged wife to rescue their daughter in San Francisco.
Destruction: The quake rips through Los Angeles and San Francisco, liquefying buildings, opening chasms in the ground, and as the coup de gras, creating a 100m high tsunami that completely inundates the Bay Area. Literally tens of millions of people are killed, trillions of dollars in destruction is created, and (spoiler alert), there is a happy ending.
Geology Sin Meter: Apocalyptic
(For a breakdown, visit The Goat’s blog at bluemarblegoat.blogspot.com)
#4. 2012
Premise: Geologists and Astronomers have discovered that the Mayan Calendar was, in fact, correct in its prediction of the “end of time”. The day: 12/21/12. Scientists realize that the Earth’s tectonic plates will “detach” themselves from the mantle and begin to spin wildly, ravaging the human race. They, along with various world leaders, put into motion a plan (large “arks”) that will spare the world’s best and brightest to begin society anew.
A failed writer, played by John Cusack, must get to one of these “arks” with his estranged wife (cough, cliché, cough), her new husband, and his two children along with a motley cast of characters including a Russian billionaire and his arm candy.
Destruction: The casualty meter in this movie along with the destruction is beyond cataclysmic. Ostensibly, billions of people are wiped out in a chain of disasters including earthquakes, the eruption of the Yellowstone Super Volcano, and worldwide tsunamis that crest the Himalayas (where scientists have pinpointed the exact time the waves will hit the “arks”). Essentially, the entirety of the human race and the world they inhabit are completely destroyed, so the scope of this movie is large to say the least. The running time is also cataclysmic, coming in at just over 3.5 hours (good god)
Geology Sin Meter: Mayan Calendariffic

#3. The Core
Premise: A university Geophysicist theorizes that the Earth’s molten core is cooling and dying given that the Earth’s magnetic field seems to be weakening (cell phones dying, birds flying north, etc.). So, a plan is hatched to bore to the center of the Earth with a machine built of a newly synthesized, indestructible element called “Unobtanium”. Armed with a laser that vaporizes rock, they tunnel to the core to set off a nuclear bomb to “restart” the core and save the planet.
Aaron Sorkin and Stanley Tucci play high-fallutin’ geophysicists (Tucci is signing autographs in one scene, and acts like a jerk through most of the movie), Hilary Swank plays an astronaut charged with commandeering the ship, and Delroy Lindo plays a long-discredited geochemist and rival of Tucci’s character. Together, the fearsome foursome must restart the Earth’s core and spare humanity from meteor showers, solar storms, and broken cell phones (In all reality, if the core died and the Earth’s magnetic field failed, life would not be possible on the planet).
Destruction: Not as much as one might think in this one. A few birds fall out of the sky, and cell phones hit the fritz, but the mass casualties and cinematic manner of destroying the Earth and everything on it are relatively non-existent. Most of the action is centered around the journey to the core, whereupon the ship encounters quite a few troubles including a layer of diamonds (LOL).
Geology Sin Meter: Off the charts. All joking aside, this is perhaps the most ridiculous movie ever made, “scientific” or otherwise.
(For a breakdown, visit The Goat’s blog at bluemarblegoat.blogspot.com)
#2. Dante’s Peak
Premise: An active volcano, similar to Mt. St. Helen’s, threatens to erupt and bury a small, idyllic Washington Cascades town. Enter Pierce Brosnan as a volcanologist, his team, and Linda Hamilton, mayor of the town during its busy summer tourist season. She predictably balks when Brosnan advises her to evacuate the town, and so ensues the battle between geology and humanity.
Destruction: Quite realistic eruption of a volcano and the fallout from it. Pyroclastic flows, lahars, ash clouds, volcanic bombs, preceding earthquakes, acid lakes, human-boiling hot springs, and the burying of a quaint little town. Not as many implied deaths as some others like 2012 or San Andreas, but that’s probably for the best. In a heroic turn of events, a grandma jumps into an acid lake and sacrifices herself for the group.
Geology Sin Meter: Volcanoriffic This movie is, for all intents and purposes, is quite geologically accurate. The eruption is measured and the team of volcanologists are closely monitoring signs of an impending eruption, while making no claims that they can actually predict it with any accuracy. Aside from a few ridiculous things such as outrunning a pyroclastic flow in a jeep, or driving that same jeep over extruding lava, this movie does itself scientifically proud.
(For a breakdown, visit The Goat’s blog at bluemarblegoat.blogspot.com)
And the #1 Best Bad Geology Movie of All-Time: Tremors
Premise: In the Perfection Valley of Nevada, way out in the badlands of the Mojave Desert, something is not quite right. When townsfolk start disappearing, a couple of local ranch hands (Kevin Bacon and Fred Ward) start trying to figure out what is happening. During their wild goose chase, they happen upon a student (Finn Carter) doing her PhD thesis on seismology in the area.
What they discover is nothing less than prehistoric underground monsters that hunt with sonar. Throw in Burt Gummer and Reba McIntyre as well-armed doomsday peppers, and you have yourself maybe the single greatest movie ever made.
Destruction: Houses get knocked down, a Volkswagon disappears beneath the Earth (and is found later by country music emanating from the ground), and Perfection Valley residents are terrorized by the large, slug-like monsters that shoot snakes from their mouths. Awesome!
Geology Sin Meter: Graboid-tastic The science in this movie is actually pretty solid, a surprise for such a goofy movie. The seismic sensors that Rhonda (Finn Carter) has set up can accurately detect the beast’s approach, as any kind of Earth or soil disturbance creates seismic waves. There is even a coherent discussion about the fossil record, and accurate conversation about the geologic time scale. Boom!
This is one of my personal favorite movies, as it is tongue-in-cheek funny with great performances by all the actors. It is fun, goofy, and foolish enough to be a good time for everyone. To boot, it stays true to not just the theoretical, but actual science (monsters notwithstanding).
(For a breakdown, visit The Goat’s blog at bluemarblegoat.blogspot.com)
So there it is people, your Top 5. Watch them over and over, they only get better with time, just like all things in geology. Read The Goat’s blog in the coming days for more deduction of the actual science in these movies, as well as discussions about scientific consultants that have worked on, or refused to work on many of these movies. So grab a bag of popcorn and a beer, grab a rock, and have good time! Cheers!

What are the Best Backpacking Trips in Grand Canyon?
Grand Canyon National Park can be a nearly overwhelming place. What do I do? Where should I go? Even for seasoned backpackers, the choices can be endless and exhausting. The Goat has compiled a list especially for you, outlining backpacking trips in Grand Canyon for all skill and experience levels. Enjoy!
5. The Hermit Loop
Time: 3 days, 2 nights
Distance: 18 miles
Difficulty: Undergraduate+ (Check out our difficulty ratings)
The Hermit Loop is a truly classic Grand Canyon backpacking trip that can be easily accomplished over a long weekend. It is a great hike for those who are looking to take their first backpacking foray into the big ditch, and truly hits all the highlights. Sweeping vistas, interesting side trips, and excellent canyon history await on a trail forged originally by the “hermit of the Grand Canyon”, Mr. Louis Boucher. The route was later improved by the Santa Fe Railroad Line in an attempt to bring mining, then tourism, into the area.
4. Tuckup Canyon via the Stairway to Heaven
Time: 7 days, 6 nights
Distance: 45 miles
Difficulty: PhD+ (check our difficulty ratings)
Get your defibrillator, this one is not for the faint of heart. Located in one of the most remote parts of Grand Canyon, this long, challenging loop is meant for experienced cannoneers only. This route takes ambitious hikers down Tuckup Canyon, past Shaman’s Gallery (recognized as one of the most spectacular rock art etchings in the American Southwest), through a traverse along the mighty Colorado River, and then up Stairway Canyon. Along the way, there are exciting climbing, route-finding, and scrambling challenges, and . Strap in!
3. Thunder River to Deer Creek
Time: 4 days, 3 nights
Distance: 28 miles
Difficulty: Graduate+ (check our difficulty ratings)
The Thunder River to Deer Creek Loop is perhaps the North Rim’s most fabulous backpacking trip. Multiple water sources, outstanding scenery, and a truly thunderous river. Geologically speaking, Thunder River is one of the most unique features in Grand Canyon. It begins as an underground river (aquifer) up on the Kaibab Plateau. It flows along various fault lines and crustal weaknesses until it breaks loose at the contact of the permeable Esplanade Group (mostly shales) and the impermeable Redwall Limestone, quite literally thundering onto the rocks below.
2. Rim-to-Rim via Phantom Ranch
Time: 3 days, 2 nights
Distance: 19 miles

This is the true Grand Canyon classic backpacking trip. Starting at the North Rim, your descent begins on the North Kaibab Trail as it winds it way down to the Colorado River. Along the way hikers are treated to unspoiled views, soaring eagles, and a well-developed trail. Thru-hikers may camp at Bright Angel Campground, or stay in the lodge at the famed Phantom Ranch. From here hikers may choose to ascend either the South Kaibab Trail (shorter, steeper) or the Bright Angel Trail (more miles) and stay the second night on the Esplanade. After cresting on the South Rim, be sure to gaze upon your North Rim starting point. This is one of the most popular trips in Grand Canyon, so be sure to make your reservations early!
1. The Escalante Route
Time: 5 days, 4 nights
Distance: 35 miles
Difficulty: PhD (check our difficulty ratings)
Carved by early Puebloan explorers of Grand Canyon, this long traverse of Grand Canyon from the Tanner Trail to Horseshoe Mesa and Grandview is perhaps one of the finest backpacking trips on the planet. There is a little bit of everything Grand Canyon here, as hikers will encounter outrageous views of the Great Unconformity, sandy beaches, a class 3 scramble over the famous Papago Wall, and a spectacular slot canyon carved from billion-year-old Shinumo Quartzite. This route confronts with hikers with the unimaginable scale of Grand Canyon, as it will seem as though you are climbing mountains in a canyon. Grand!

How was The Wave Formed?
Hiking on the Colorado Plateau is a constant game of “how did this get here?” and “why does this look this way?”. Everywhere a hiker looks, they are confronted with wild rock formations, howling desert wilderness, and geology on a nearly incomprehensible scale. The mere presence of this place has led countless professional geologists and outdoor enthusiasts alike to spend lifetimes exploring the fabulous scenery and enormous scale. From Grand Canyon to The Arches, from Antelope Canyon to The Subway in Zion, the Colorado Plateau contains some of the most fantastic and intense scenery in the world.
The Wave, in all of its glory
The Wave, however, is perhaps the single most-famous stand-alone feature in this wild landscape. Of course, the most often-asked question about The Wave (besides maybe how do I get a permit) is how was The Wave formed? The short answer: geology. The long answer, and the much more interesting one, begins nearly 200 million years ago. Let’s go time traveling!
The Jurassic: Wind-blown Sand Seas
The time is 180 million years ago. The place is at the southwestern margin of the supercontinent Pangea. All of Earth’s tectonic plates have assembled themselves into one, massive block of puzzle pieces. Dinosaurs roamed the landscape, but if you were standing here at the time, you would see very few living things. Here, you scramble to the top of 100 foot-high mountain of sand and gaze out over an unforgiving, desolate, and stark landscape. This is the birthplace of The Wave.
The landscape before you is thought to be the largest sand-dune desert in the history of the Earth, stretching hundreds of miles in each direction, from the ancient Pacific ocean in the west to modern-day New Mexico in the east; from modern-day Mexico in the south to what is now Wyoming in the north. Outside of the occasional desert oasis, this is a lifeless, hostile place. Trade winds blow massive amounts of sediment from the eroding Ancentral Rocky Mountains and the rising Appalachian Mountains southwest towards the ocean, forming monstrous sand dunes that migrate across the landscape like a giant game of Pac-Man, with dunes piling onto and devouring each other in the relentless winds.
As you stand upon this giant dune and wonder what is to become, you step into your time machine. Closing the door and making sure the windows are squeaky clean for maximum viewing, you begin your journey over the next 180 million years. Buckle up!
Burial, Cementing, and Uplift
Through your windows, you witness the close of the Jurassic, and the beginning of the Cretaceous. The climate cools and becomes wetter, ushering in a gradual but stark change in the environment. The Cretaceous Interior Seaway encroaches upon the land as the tectonic plates continue to shift, slowly breaking apart as Pangea slowly morphs into the modern map. The former sand dune upon which you stood sinks into the landscape and is buried by a warm sea bordered by humid swamps and yet more dunes.
Panorama of scenes in the Vermillion Cliffs
To the west, the Pacific Tectonic plate pushes its neighbor, the Farallon Plate, under the North American Plate at a very low angle, giving rise to the Laramide Orogeny and modern-day Rocky Mountains. This uplift carries away the seas, and sets the stage for the modern landscape to emerge. In the distance, you see an intensely bright light in the sky, followed by an impact that is felt around the globe. An asteroid has pounded the Earth in what is now the Gulf of Mexico, ending the reign of the dinosaurs and the Cretaceous.
Oh, there is just one more thing….
The canvas upon which the landscape seen in photographs today is set for the artist of geologic time; erosion. However, before the final masterpiece is created there is one more incredibly important thing that must occur: the unique uplift of what will become the Colorado Plateau. As the Farallon Plate sinks into the mantle, it behaves in a peculiar manner. Typically, tectonic plates behave in a ductile manner as they are heated, flexing in a pliable way as they are resorbed into the mantle.
However, the Farallon Plate behaves in no such way. Instead of acting in a ductile manner, it behaves in a rigid, brittle manner; perhaps due to the low angle of subduction. A large piece breaks away from the whole, becomes buoyant, and is thrust back towards the surface. This piece of plate forces the surface above it to rise several thousand feet above sea level, and causes land to the west to begin extending back out to the west over the Pacific Plate. Here, on this uplifted and exposed surface is where the masterpiece will be painted.
Wind, Water, and Time
At this point, The landscape seems relatively flat and featureless. The Rockies loom on the eastern horizon, but the familiar modern landscape is buried under millions of years and thousands of feet of sediment accumulation. After all, the Navajo Sandstone is but one geologic unit and one small snapshot in time in a region that has been built quite literally one grain of sand/clay/lime at a time over nearly 550 million years.

But, the stage has been set. The time has come. The sediment is deposited. The uplift has exposed it to the elements. Now the combined forces of wind, water, and time take their turn. We are in the Neogene period, about 20 million years ago. The Neogene period itself is not well represented by sediments or deposition on the Colorado Plateau.
Therefore, it is difficult to say precisely what environmental conditions existed. However, what we can say for certain is that, beginning in the Neogene, the Colorado Plateau began to undergo a sustained and intense period of erosion and deep dissection. This period continues to this day as the high plateau is exposed daily to the ravages of winds, pulsated by short periods of intense precipitation (rain and snowstorms). In addition, the general conditions of the desert make this place quite inhospitable to large and widespread plant life. This helps foster the erosive forces carving into the rocks, and leaves them uncovered for all to view in their splendor. Yay for us!
Okay, great. Get to the point!
You came here to know how The Wave was formed. Let’s talk about that! As discussed, numerous specific things had to occur for this feature to be created. All of those things have now happened, and we are ready to form The Wave. Strip away the overlying sediments, down into the sleeping Navajo Sandstone. Neogene period, got it. 15-20 million years ago, check. Erosion, check. But this feature, specifically?
The nature of the Navajo Sandstone in Vermillion Cliffs
The Wave is the specific result of small trickles of water contouring their ways through the Navajo Sandstone, followed by long, sustained periods of wind. As we discussed, prior to deep dissection the area was a flat-ish, blank canvas. During periods of rain, water follows the path of least resistance due to gravity. This feature of water allows it to create “nickpoints”, or places that are routinely exposed to water flows and erode faster than areas where water does not flow. Yep, this all checks out. So what?
The Formation of The Wave
So what, you say? This is what. The Wave’s appearance began very carefully with small trickles of water cutting into one particular “nickpoint”. After water carved the niche, wind took over. From that small nickpoint, the wind howled though relentlessly over the many millions of years afterwards (15+ million). Punctuated by alternating winds and small trickles of water, The Wave was carefully and painstakingly carved from the sandstone. Surf’s up!
That’s how the feature itself was formed. A deeper question is this: why does it look this way? (with the waviness and lines?). Elementary, my Dear Watson! The Navajo Sandstone, of course! You see, as we’ve discussed, the Navajo Sandstone was deposited as large sand dunes. Sand dunes are formed by layers of sand piling upon one another, then avalanching down the front face as the dune migrates. The avalanches and migrations are preserved as wavy lines, revealing the internal structure of the dune. It is known in geologic terms as “planar-tabular cross bedding”.

In effect, the dunes are waves, just made of sand instead of water. Therefore, The Wave is truly a “wave”; petrified waves of stone.
The Future of The Wave
The geologic processes that formed The Wave are, ironically, the same that will destroy it. Current geologic processes are exposing the Colorado Plateau to erosion. These processes are likely to continue into the near-term (several million years) geologic future barring some catastrophic event or sequence of events.
However, you can rest easy knowing that The Wave, along with most of our favorite features in canyon country are here to stay for the foreseeable human future. Enjoy!
Going Guided
Hiking and exploring The Wave located in Coyote Buttes in southern Utah and northern Arizona is an incredible experience. There are few hiking trails in the southwest that come close to the sheer awe that is induced while seeing The Wave for the first time. While securing permits can be a challenging affair, it’s totally worth it. Hiking The Wave is something everyone should experience in their lifetime.
Although it is possible to see these places yourself, hiring a guiding outfitter is a great idea. For instance, guiding services provide logistical support, and plan everything for your best possible trip. They provide a great safety net on the trail, and are trained in backcountry medicine. Above all, they provide a depth of knowledge of the region that turns a walk into a true adventure.
**Remember, you cannot hike or visit The Wave without a permit! Getting caught without a permit is a bad situation.**
