The 161 km wide western North American Fold and thrust belt extends from Alaska to Mexico, forming several northerly trending thrust faults in southwest Wyoming, including the Crawford, Absaroka and Hogsback (Darby), which formed from the Late Jurassic through the early Eocene. The Painter Reservoir Field[9] was discovered in 1977 from the 407 m thick Nuggest Sandstone which forms an anticline structural trap in the hanging wall of the Absaroka thrust plate, at a depth of about 3 km.[10]
