Highlights include Canyon very different from others; at head + foot typical V-shaped. In middle like glacier trough, but no glacier deposits. On floor some rock weakness is explanation. Black and white rocks on the other side are different than found here. Caused by faulting. Balancing between weathering and erosion. Station 2 Contact between Pre-Pennsylvanian, Sediments are massive limestone fossiliferous not over five feet off contact. We are western side of Laramie Arch. Rocks are dipping basinward. Range is about 20 miles wide and 150 miles long. Sediments cap highest portion.
