Northern Utah’s Wasatch Mountains are popular destinations for outdoor enthusiasts in every season. These mountains rise spectacularly from the relatively flat valley floor to thirteen peaks over 11,000 feet in elevation. An additional nineteen peaks rise more than 10,000 feet in elevation. Although many hiking guides exist for the Wasatch Mountains, there has been no guide book that focuses on the geologic features visible from the trails—until now.Written by a recognized authority on the geology of the Wasatch Mountains, this guide is meant to enrich the experience of outdoor enthusiasts who want to understand the geological history and development of the Wasatch range. The first section of the book introduces the major geological time periods—the record of mountain building events from oldest to youngest, the effects of glaciation, and the development of the present topography. It then follows with a descriptive trail guide for each major trail system, including Mill Creek and Neffs Canyons, Mount Olympus, Little and Big Cottonwood Canyons, and Bells Canyon. Trail length, elevation gain, relative difficulty, and major geological features are outlined for each trail. Now you can hike these trails with the answers to all your geologic questions right at your fingertips.

About 12,000 years ago, a major river ran from the Sevier Basin to the Great Salt Lake, feeding a wetland delta system and creating riparian habitat along its length. But after three thousand years the river dried up and the surrounding lands became more like what we see today. Because the Old River Bed Delta experienced less environmental and human disturbance than other areas, many of the Paleoarchaic sites found there have remained relatively intact—a rare find in the Great Basin. This book presents a comprehensive synthesis of a decade of investigations conducted by research teams working in different parts of the delta and explores questions about how the old riverbed was formed, how its distributary system changed through time, and how these changes affected early foragers. It concludes with an integrated summary and interpretation. Additional material from this study will be available online at UofUpress.com.
