UGS geologist, Bob Biek, investigating the geology of an area in order to create a geologic map. It takes a geologist working full-time 6 to 12 months to complete a map and explanatory materials for a typical 7.5′ quadrangle.

The Geologic Mapping Program maps Utah’s geology at scales of 1:24,000 (7.5 minute quadrangle maps) to 1:100,000 (regional maps). These maps and accompanying booklets describe stratigraphy, structure, Quaternary geology, geologic hazards, economic geology, ground-water resources, and scenic geologic resources. UGS geologic maps are used by geologists, government officials, industry representatives, and the public to better understand Utah’s geology, delineate the economic value and potential of property, and assess geologic hazards.

Geologic Mapping Projects

In addition to projects funded by the Utah Geological Survey, the Geologic Mapping Program applies for matching funds from federal sources to increase the rate of geologic map production. Currently, funding is obtained through the National Cooperative Geologic Mapping Program administered by the U.S. Geological Survey, and the Geologic Resources Division of the National Park Service.

The Utah Geological Survey also has provided funds to outside contractors, mostly professors at local universities and graduate students, to produce geologic maps of quadrangles in which they have research interests. This program has resulted in over 20 geologic maps during the last several years.

Field Reviews

Field reviews are designed to give the public and local government officials an opportunity to learn about the geology of areas that were recently mapped by the Geologic Mapping Program and to give geologists (or anyone else) an opportunity to critique the maps and offer suggestions before they are published. All field reviews are free and are open to anyone. Most require some strenuous hiking.
