44.609216, -108.141705 - Facing North Sheep Canyon is a look through the cross section of the Sheep Mountain Anticline, changing direction from north to north-east through its midsection. Due to differential weathering, the massive walls of the gray/cream colored limestone of the Mississipian Madison Limestone compose the majority of the canyon walls - while the generally recessive red siltstones and shales of the unconformably overlying Amsden Formation can only be seen near the top of the canyon. The traintrack running along the Big Horn River provides transport for the many bentonite plants in the town of Greybull - just south of the Sheep Mountain Anticline. An amazing feature of the folding present here is the relative fluidity with which they have been bent - exhibiting little faulting to compensate for the stress that must have been applied to fold these relatively brittle rocks to this degree (Though if you look closely there are some minor reverse faults in this picture). This is especially true when examining the tightly folded nose - hinge to the north.
