The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes.
The Wyoming Thrust Belt Province is located in southeastern Idaho, north central Utah, and southwestern Wyoming, encompassing all or parts of Bannock, Bear Lake, Bingham, Bonneville, Caribou, Franklin, Jefferson, Madison, and Teton Counties in Idaho and all or parts of Box Elder, Cache, Davis, Morgan, Rich, Salt Lake, Summit, and Weber Counties in Utah and all or parts of Lincoln, Sublette, Teton, and Uinta Counties in Wyoming. The main population centers within the study area are Soda Springs and Montpelier, Idaho; and Morgan and Coalville, Utah; and Evanston and Kemmerer Wyoming. The main highways, I-80 and U.S. 30, generally traverse the area from east to west with U.S. Route 89 running north to south. The Snake River and its tributaries drain the area. The province boundary was drawn to include the geologic structures generally considered to be in or bounding the Wyoming Thrust Belt Province.
