Abstract

The Dead Horse Point geosite, within the state park by the same name, is located in the heart of the Canyonlands region of Utah between Canyonlands and Arches National Parks. The views are spectacular, sublime, awe-inspiring, and majestic, and hard to surpass anywhere on the Colorado Plateau. The mood of the vistas changes by season and time of day. Here, one of nature’s engineers, in this instance the Colorado River and its tributaries, has carved and exposed strata of Late Pennsylvanian (307 million years ago [Ma]) to Early Jurassic (200 Ma) age within just the past 5 million years (figures 2 and 3).

Summary

Presidents Message

I have had the pleasure of working with many different geologists from all around the world. As I have traveled around Utah for work and pleasure, many times I have observed vehicles parked alongside the road with many people climbing around an outcrop or walking up a trail in a canyon Whether these people are from Utah or from another state or country, they all are quick to mention to me how wonderful our geology is here in Utah. We thank the many authors for their geosite contributions, Utah Geological Association members who make annual UGA publications possible, and the American Association of Petroleum Geologists—Rocky Mountain Section Foundation for a generous they consider unique and want to share with the rest of us. But not least, Thank you to the American Association of Association website, www.utahgeology.org, and Creative Commons Petroleum Geologists, Rocky Mountain Section Foundation for https://creativecommons.org/licenses/by/4.0/ for details
