Overview
The purpose of this site is to make Utah’s (and the Colorado Plateau’s) geology accessible to all and easy to learn. Utah already ranks third in the nation for national parks and monuments (behind only Alaska & California). This is a direct result of the states very unique geology. Zion, Bryce, Arches, Capitol Reef, Canyonlands, The Grand Staircase, Glen Canyon, and the Grand Canyon attract millions of visitors every year because these areas display the earth’s strata in a unique and spectacular way rivaled by few places on earth. This site tries to compliment these incredible geologic exposures of the Colorado Plateau by supplying a database of pictures and information which will aid those seeking to understand its unique geology.

The Author
This site is being built by a single author (me!), and will be a lifelong project. I have a Degree in Geology and  currently work full time at the Utah Geological Survey; working on a variety of projects and web development. Pretty much all of my recent work is on the Utah Geological Survey’s website found at http://geology.utah.gov.  The purpose of building this site is to make available the learning tools which I wish I would have had as I first applied myself to master the geology of the Colorado Plateau. Or to act as a staging area for projects I’m working on at the Survey. It has been my desire to understand the stratigraphy of this area as well as anyone and, as I work toward that end, I wish to help others understand that which I learn.

Background
I grew up in St George, Utah (located in the southwestern corner of the state). As a high school student I became captivated by maps. Hiking was my favorite pastime and I began to acquire topo maps in order to fulfill my goal to hike every canyon in nearby Zion National Park. As I started buying topo maps for Zion, I slowly expanded my area of interest. I bought every 7.5 Minute series topo map for Washington County and taped them together on my wall. They ran floor to ceiling and wrapped around two walls. I was fascinated by the way maps allowed me to come to know a place without even being there–and better understand it once I was there. I would sit and memorize them for hours and try to guess what a canyon would look like before I hiked it.

Later I began to acquire aerial photos, satellite imagery and geological maps as well. I am captivated by them. The more I learn about an areas geology and physiography – the more I want to know about what makes it the way it is. I believe that the more perspectives we can view an area with, the more we appreciate what’s there. I am also very interested in cosmology, history, religion and in debates such as evolution and the age of the earth. I think there is a lot more to this blue marble on which we live than meets the eye, but in the end… I don’t really care about all that stuff as much as I care about enjoying and having fun with my family.

This site is basically a compilation of all the resources I wish I had when I was first trying to learn Utah’s geology. And since I still have a lifetime of learning to do, the site will continue to grow, as I pass along the things that help me to view the earth from as many angles as possible.
