Utahgeology.com 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.


Lance Weaver Bio
Welcome to Utah Geology! I began building this site nearly 20 years ago as a labor of love for sharing my passion for Utah’s geology. I have degrees & graduate training in Geology & Geophysics, and have worked in Public Outreach for the Utah Geology Survey for around 15 years as a Geologist pioneering their Data Management Program which helps to disseminate the research of our 60+ scientists to the public through interactive and engaging means.

I am a pioneer in the geologic visualization space, creating perhaps the first state interactive geologic map visualizations way back with the very first release of Google Maps. At the UGS I’ve gained national notoriety for envisioning, designing and coding our 3D Map Portal, mapping application, which has consistently been among the top Interactive Geologic Mapping applications in the Nation. Working in information outreach and data management I’ve found unique ways to make our agencies scientific research more readily available to the public (primarily through articles, online storytelling and 3d visualizations and mapping applications). I’ve published more than a dozen circular articles on the geology of Utah, and am continually publishing additional geologic material, visualizations and ideas on my website.

My Story
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 floor to ceiling on my bedroom 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, attempting to accomplish a goal of exploring every possible canyon in the region.

Hiking with my family.

Later I began to acquire aerial photos, satellite imagery and geological maps as well which entirely captivated me. 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.

In my personal research I also specialize in general prehistoric paradigms, stratigraphic paleo-reconstructions and making complex scientific research digestible to the public through computer mapping visualizations. As well as geoarchaeology or the interaction of archaeology with earth systems (especially in regard to earth’s magnetic field, radiometric dating and ice ages). By hobby, I consume history, physics, channeled literature and spiritualism. In practice, I am mostly a father, tour guide and nature explorer.
