... Polecat Bench terrace of the Shoshone River rises 6–7 m over the axis of the Frannie anticline; this displacement may be related to folding or faulting since 1.4 Ma. Near the Nye-Bowler–Sage Creek and North Pryor faults in the Pryor Mountains, bedrock is 25 and 55 m shallower than depths predicted from...
