Almost ten years ago, on January 7, 2008, I posted the first entry on Geotripper. I had no idea where it would go, or how long it would last. A century, I guess, in blog years. I had not done a lot of writing before starting the blog, but I had a great many digital images to share, and some occasional stories to go with them. We will reach a couple of milestones this year, the 2,000th post, and possibly 3 million total hits, depending on how accurate Google counter is (Stat counter says 1.8 million). It's also been a wonderful opportunity to meet so many people from all over the world as they respond to posts.
So...this week I am dredging through some of the archives to find some of my favorite posts from over the years. I'm starting with my first organized blog series on the geologic history of the Colorado Plateau, "Time Beyond Imagining". I began the series in July of 2008, and finished much later in October of 2009. There was enough material that I eventually compiled the story into a field guide I produced for the AAPG.
In any case, if you have any interest at all in the geology of the Four Corners region, and want to learn more about this fascinating landscape, check out the story below...
From July 1, 2008:
Please forgive me for filling the feeds with such a long post, but I wanted to pull together an annotated list of the blog posts of my just completed journey through the geological history of the Colorado Plateau. It turned into a massive project that lasted more than a year, and included seventy different postings and more than a hundred photos. Don't feel compelled to try reading it, but I hope you enjoy it if you do. If it lacks precise continuity and style, remember that I had no idea how it would end when I started it and I had no editor! I've been taking students on the plateau for twenty years, and it has proven to be one of the best places on the planet to learn earth history.
Time Beyond Imagining, the first post back in June of 2008 introducing the concept that would guide the entire series. I had no idea what I was getting into!
Time Beyond Imagining - An Intro to the Colorado Plateau, a first introduction to the sweep of the landscape that I would be covering through the series.
Time Beyond Imagining - The Oldest Rocks on the Colorado Plateau: The oldest rocks are exposed at only a few places, including deep in the Grand Canyon
Time Beyond Imagining - A Brief History of the Colorado Plateau, Part 2: A discussion of the 12,000 feet of sediments hidden deep in the depth of the Grand Canyon dated at around 1 billion years

Time Beyond Imagining - A Brief History of the Colorado Plateau, Part 5: Seeing Red Looking at the Mississippian Redwall Limestone in Grand Canyon
Time Beyond Imagining - A Brief History of the Colorado Plateau, Part 6: Seeing Red (Really!) We rise up through the walls of the Grand Canyon to the Permian rocks of the Supai Group and Hermit Shale
Time Beyond Imagining - A Brief History of the Colorado Plateau, Part 7: Mountains Rise: Permian rocks are exposed throughout the plateau country. We leave the Grand Canyon and explore some of these other places
Time Beyond Imagining - A Brief History of the Colorado Plateau: Old Salt I was beginning to realize that the project would be longer than I thought. We explore the formation and effects of salt precipitation in Late Paleozoic time
Time Beyond Imagining - A Brief History of the Colorado Plateau: Sand! A return to the Grand Canyon and the prominent Coconino Sandstone near the rim
Time Beyond Imagining - A Brief History of the Colorado Plateau: A Final Transgression Looking at the top two layers in the Grand Canyon and related rocks on other parts of the plateau.
Time Beyond Imagining - A Brief History of the Colorado Plateau: On to the Grand Staircase An introduction to the Mesozoic history of the plateau country, which lies outside the Grand Canyon. We start exploring the other wonderful parks out there
The Grand Staircase and the Geologic Time Scale A diagram of the Grand Staircase, the younger rocks of the Colorado Plateau
Time Beyond Imagining - A Brief History of the Colorado Plateau: Into the Triassic An introduction to the widespread Triassic rocks of the Plateau. It would prove to take a number of posts!
Mid-week Mystery Sample: What is it? A short departure to discuss the identity of a Triassic fossil from the plateau. A fairly long discussion followed!
Mid-week Mystery Sample: What is it? Heck if I actually know! I admit to my ignorance...
Time Beyond Imagining - A Brief History of the Colorado Plateau: Ash and Wood A study of the paleontology of one of our unusual parks: Petrified Forest in Arizona

The Real Jurassic Parks: Arches National Park, continued. And an Eminent Threat. After several weeks I got back to work with a continued exploration of Arches, and discussed new threats to parks in the region
The Real Jurassic Parks: Where are the Dinosaurs? A look at wonderful Dinosaur National Monument and a rotten political situation there
The REAL Jurassic Parks were really Cretaceous I thought the Jurassic would provide the most posts in the series, and therefore had no idea how long I would spend in the Cretaceous. This was the introduction
The Cretaceous Parks of the Colorado Plateau: the Cedar Mountain Formation The only dinosaur dig I ever took part in was in an early Cretaceous formation in Montana, but it was related to the Colorado Plateau. This post turned into seven part story on our adventure
The Cretaceous Parks of the Colorado Plateau: the Story of a DinoDig Much of the story was trying to get there in the first place: what is geokarma?
The Cretaceous Parks of the Colorado Plateau: Every Cloud has a Golden Lining We drive through Yellowstone and arrive at the dig site
The Cretaceous Parks of the Colorado Plateau: the story of a Dino-Dig What we were looking for and why it was important. What is a deinonychus?
The Cretaceous Parks of the Colorado Plateau: the Dino-Digging Begins This is what grunt work is all about
The Cretaceous Parks of the Colorado Plateau: the story of a Dino-Dig wraps up We started finding bones!
The Cretaceous Parks of the Colorado Plateau: the Final Discovery We found a dinosaur that invariably is the last entry in a dinosaur dictionary...
The Cretaceous Parks of the Colorado Plateau: The View is Nice but Access is a Problem... Back on the plateau, we are introduced to the remaining Cretaceous rocks and two archaeological parks, Hovenweep and Canyons of the Ancients National Monuments
The Cretaceous Parks of the Colorado Plateau: Walled Cities and Tragedy More on the Canyons of the Ancients and a walled medieval-aged city...in southern Colorado!

The Cretaceous Parks of the Colorado Plateau: A City in the Wilderness Life had become busy and it was a month before I returned to the plateau with a discussion of Chaco Culture National Historical Park
And The Old World Passed Away... The Geologic History of the Colorado Plateau And another month passed! I tried to find the words to describe the profound events at the end of the Cretaceous Period
Time Beyond Imagining - A not-so-brief History of the Colorado Plateau Another long gap, but I was finally talking about the last 65 million years of Colorado Plateau history with an intro to the crustal deformation that was beginning to effect the region
Time Beyond Imagining - Land of Giant Lakes A discussion of the origin of the rocks at Bryce Canyon and Cedar Breaks National Monument. I thought I was close to the end, but I was still wrong, after a full year!
Fire Down Below - a Geological History of the Colorado Plateau Another month of blogging on other things and I returned to the Cenozoic history of the region with a discussion of the volcanic activity that started to emerge on the plateau, including Shiprock
Fire Down Below II - a Geological History of the Colorado Plateau The laccolithic mountains of the plateau country
Fire Down Below III - a Geological History of the Colorado Plateau I find I have almost no pictures of Navajo Mountain despite having driven around it dozens of times...
Time Beyond Imagining: A Scrambled Landscape Cenozoic events led to a truly scrambled landscape with a mystery-of-the-day

Time Almost Not Beyond Imagining: Recent Volcanism on the Colorado Plateau Part 2 A look at the volcanoes in the western Grand Canyon and how they formed massive lakes in the Grand Canyon, some 200 miles long!
Time Almost Not Beyond Imagining: Recent Volcanism on the Colorado Plateau Pt. 3 The story of a stupendous rhyolite eruption at the Jemez Caldera in New Mexico
Time Almost Beyond Imagining: Who Do the Magic that Hoodoo? My favorite title for a discussion of a unique park near the Jemez Caldera, Kasha-Katuwe Tent Rocks National Monument
Time Almost Not Beyond Imagining: Recent Volcanism on the Colorado Plateau and Deep Time Although I had reached the last million years of a two billion year history, I felt a need to try and describe the immensity of geologic time, using the ruins of Bandelier National Park and the Jemez Caldera
Time Beyond Imagining - Where did the Ancient Enemy Go? The "disappearance" of the Ancestral Pueblo people is explored at Bandelier National Monument
Time Beyond Imagining: Why Can't We Touch the Venus de Milo? Once again, I thought I was done, but found a series of fascinating (to me) stories about research in the limestone caverns on the plateau. I began with a rant about preserving these wonderful caves that took us to Rome and Paris, of all places
Holy Crap, Batman! The Bat Cave is Full of it! Bat Cave in western Grand Canyon, and bat-sh*t. Lots of it, sort of
Holy Smokes, Batman, that crap is on fire! I was saving my best titles to the last, I guess. A horrific crime against science at Rampart Cave in the Grand Canyon
Of Rat Pee and Uranium and Scavengers...The Underground Story of the Ice Ages on the Colorado Plateau What the caves on the plateau tell us, and how.
Time Beyond Imagining - A Final Struggle for Life on the Colorado Plateau I imagine the death of the very last mammoth on the Colorado Plateau
Time Beyond Imagining: The End of the Story, or the Beginning? In the final post of the series, I discuss the arrival of humans on the plateau, and how humans change the land they occupy. I also tip my hat to Ken Burns and his series on "The National Parks: America's Greatest Idea". The parks are the laboratories in which I and my students study the history of the earth.
So there you go: 71 posts that tell a story encompassing 2 billion years as it is exposed on a very special part of the earth's surface: the Colorado Plateau, covering parts of Arizona, Utah, Colorado, and New Mexico. Congratulations if you ever made it through the whole thing. I never realized I was writing the equivalent of an entire book, but it was a story I truly enjoyed telling, and I also deeply appreciated the feedback that many of you provided.
