Sheep Mountain Canyon
Sheep Mountain, north of Greybull Wyoming, is a highly dissected anticline. At it center lies a prominent 15 mile long ridge which corresponds to the double plunging anticline’s crest. The photo shows the southwest end of the canyon cut by Bighorn River through the anticline’s core about 1/3 of the way along the ridge from its north end. Sheep Mountain Canyon measures about a 1,000 feet deep at its maximum. The Mississippian Madison Limestone makes up most of the cliffs in the photo above. The Pennsylvanian Amsden and Tensleep Sandstone overlie the Madison as seen in the upper lefthand corner of the photo. The Sheep Mountain anticline is a Laramide fold that formed along buried back thrust faults. This view shows the southwest limb of the fold. The northeast limb is steeper.
