Striking beauty, abundant recreational opportunities, historic mining and pioneer locales, and a unique geologic story stretching back over one billion years make Salt Lake County’s Wasatch Front canyons a world-class attraction. This guide highlights the six canyons open to vehicles. Topical pages present the region’s fascinating geologic history and active processes, while descriptions and maps with road mileage further explain each canyon’s geology.

This bulletin serves not only to introduce the non-geologist to the rich geology of Millard County, but also to provide professional geologists with technical information on the stratigraphy, paleontology, and structural geology of the county. Millard County is unique among Utah’s counties in that it contains an exceptionally complete billion-year geologic record. This happened because until about 200 million years ago the area of present-day Millard County lay near sea level and was awash in shallow marine waters on a continental shelf upon which a stack of fossil-bearing strata more than 6 miles (10 km) thick slowly accumulated. This bulletin summarizes what is known about these strata, as well as younger rocks and surficial deposits in the county, and provides references to scientific papers that describe them in greater detail. Mountains North 30 x 60 (1:100,000-scale) quadrangles. These companion maps and this bulletin portray the geology of Millard County more completely and accurately than any previously published work.

This report presents the results of the Utah Quaternary Fault Parameters Working Group (hereafter referred to as the Working Group) review and evaluation of Utah’s Quaternary fault paleoseismic-trenching data. The purpose of the review was to (1) critically evaluate the accuracy and completeness of the paleoseismictrenching data, particularly regarding earthquake timing and displacement, (2) where the data permit, assign consensus, preferred recurrence-interval (RI) and vertical slip-rate (VSR) estimates with appropriate confidence limits to the faults/fault sections under review, and (3) identify critical gaps in the paleoseismic data and recommend where and what kinds of additional paleoseismic studies should be performed to ensure that Utah’s earthquake hazard is adequately documented and understood. It is important to note that, with the exception of the Great Salt Lake fault zone, the Working Group’s review was limited to faults/fault sections having paleoseismic-trenching data. Most Quaternary faults/fault sections in Utah have not been trenched, but many have RI and VSR estimates based on tectonic geomorphology or other non-trench-derived studies. Black and others compiled the RI and VSR data for Utah’s Quaternary faults, both those with and without trenches.

Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.

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.

Geologic exposures in the Salt Lake City region record a long history of sedimentation and tectonic activity extending back to the Precambrian Era. Today, the city lies above a deep, sediment-filled basin flanked by two uplifted range blocks, the Wasatch Range and the Oquirrh Mountains. The Wasatch Range is the easternmost expression of major Basin and Range extension in north-central Utah and is bounded on the west by the Wasatch fault zone (WFZ), a major zone of active normal faulting. During the late Pleistocene Epoch, the Salt Lake City region was dominated by a succession of inter-basin lakes. Lake Bonneville was the last and probably the largest of these lakes. By 11,000 yr BP, Lake Bonneville had receded to approximately the size of the present Great Salt Lake.

The wonderfully grotesque stone sculptures that are Goblin Valley State Park’s main attraction are the consequence of millions of years of geologic history. Within the park are rocks composed of sediments from ancient seas, shorelines, river channels, and playas. With the passage of time these layers of sand, silt, and clay became deeply buried and transformed to rock. Much later, large-scale tectonic forces uplifted the area and prompted erosion to begin to expose the deeply buried layers of rock. Once the rocks were back on the surface, fractures and variations in hardness within the rocks facilitated carving of the goblins by the erosional power of water, wind, and frost. Understanding the rocks and structures of Goblin Valley State Park requires not only an investigation of past and present events that have acted on a small scale within the park, but of past large-scale tectonic events and processes. This booklet is intended to further your understanding of the formation of the goblins, soils, and surrounding scenery or “how they came to be.”
