Surface geologic mapping, regional and high-density reflection seismic data and information from approximately 370 wells. Verification of two-dimensional interpretations of multiple thrust sheets by linear restoration. Structural geometries. 47 cross sections. Displacements of 0 to 32 mi. Jurassic to Paleocene (Sevier) thrusts were active across a previously deformed cratonic shelf terrane and interacted with active structural elements such as the Uinta Uplift, Gros Ventre Range, and Moxa Arch. Thrusts are progressively younger to the east.--Modified journal abstract.
