Provo Peak
The upper reaches of Rock Canyon ascend to the summit of Provo Peak (11,068 feet). Near the summit, glacial cirques are evident from this glacial period. Most mountains in Utah above 9500 feet were affected by Pleistocene glaciation.
Another interesting feature to notice in the picture is the parallel terraces carved into the steep mountainside at the bottom left of the image. During the period of time between 1880 and 1930 these slopes, as well as other spots in the Wasatch Mountains, experienced numerous rock and mudflows during spring runoff. A study was conducted to determine the cause of the floods. It was determined that because of over-grazing by sheep, over time, that the slopes had become unstable due to lack of vegetation. In the 1930's Silvester Q. Cannon undertook the project to slow erosion and seasonal flooding. Using funds and manpower from the, newly formed government program, the Civilian Conservation Corps or CCC project was engaged to carve large terraces in the hillside to slow the runoff and stabilize the slope. Bulldozers and dozens of men created the sloping terraces that are still visible from Provo.
