GEOLOGICAL SURVEY
The Utah Geological Survey consists of five geological programs, including Energy & Minerals, Geologic Hazards, Geologic Information & Outreach, Geologic Mapping and Groundwater & Paleontology. Collectively, all five programs provide timely scientific information about Utah’s geologic environment, resources and hazards.

Energy and Minerals
UGS identifies, characterizes and quantifies Utah’s energy and mineral resources. It manages the Utah Core Research Center which maintains computerized databases and other files on Utah’s past and present resource development activities. The research center responds to requests for information about the state’s energy and mineral resources from individuals, governmental agencies and industry.

Geologic Mapping
To promote better understanding of Utah’s geology and hazards, UGS maps the state at 1:100,000 and 1:24,000 scales (digital and print). These geologic maps are provided to geologists, government officials, industry representatives and the public.

Geological Information and Outreach
The UGS outreach program provides information on Utah’s geology to the public, educators, industry and decision makers. We produce non-technical, geologic-overview and educational publications on a variety of topics. We also operate the Natural Resources Map & Bookstore and the Department of Natural Resources Library and provide resources, field trips and workshops to teachers.

Geologic Hazards
The Survey responds to requests from government agencies for geologic hazards investigations and report reviews. We also help protect Utah’s public health and safety by investigating and mapping hazards; responding to emergencies; compile small- and large-scale geologic hazard maps and provide technical services.

Groundwater and Paleontology
The program provides state government and the public with detailed paleontological studies on ground-water resources. The Survey issue permits for fossil excavations and directs paleontological training programs.

What geological hazards might threaten my home?

Utah has a variety of geologic hazards that include earthquakes and faults, landslides and rockfalls, earth fissures and ground cracks and radon. Visit the UGS hazards page for more information.

Where can I collect minerals or landscaping rock on public lands?

Utah is a rockhounder’s paradise and full of rock and mineral collecting sites

What resources do you have available for teachers?

UGS produces education materials on geology, geologic resources, hazards and landscapes of Utah. We also loan teaching kits on rocks, minerals and fossils; land forms of Utah; dinosaurs and the Ice Age. We provide hands-on activities for school groups to celebrate Earth Science Week; write a Teacher’s Corner column in the UGS newsletter Survey Notes and respond to requests for educational materials and assistance

Why is the Great Salt Lake salty?

Much of the salt now contained in the Great Salt Lake was originally in the water of ancient Lake Bonneville. Even though Lake Bonneville was fresh, it contained salt that concentrated as its water evaporated. Additionally, every year rivers flowing into the lake deposit about two million tons of dissolved salts that have leached from the soil and rocks

What was Utah like during the Ice Age?

With roaming mammoths, muskoxen, saber-toothed cats, giant ground sloths and many other now extinct animals; active mountain glaciers; and a fresh-water lake covering much of western Utah, that state was a very different place during the Ice Age
