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!

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?

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.
