The North Ridge quadrangle is located in north central Wyoming, on the western margin of the Powder River Basin and east flank of the Bighorn Mountains. Previous work in the area identified the Clear Creek Thrust Fault; this study identified an additional splay of the fault south of Highway 16. This study also provided more detailed mapping at a larger scale. Bedding and foliation orientations were documented across the map area, and faults were precisely located. Locations of the gradational contact between the Wasatch, Kingsbury and Moncrief units were more closely located where exposed.
