[[:file:exploring-for-structural-traps_fig20-5.png|Figure 1]] depicts the tectonic setting for the western U.S. relevant to Laramide plate tectonics. It shows where overthrusting took place, its overall geometry and ver-gence direction, and the interference with foreland deformation.

Within the structural domains, regional analysis of structural style and timing were integrated with other elements of the hydrocarbon system to define prospective fairways. [[:file:exploring-for-structural-traps_fig20-7.png|Figure 3]] covers approximately the same area as the preceding satellite image and shows the location of the major thrust sheets in the Wyoming thrust belt. Note that most of the oil and gas fields occur in the southern half of the Absaroka thrust sheet.
