Abstract
The Manti Canyon area is on the east side of Sanpete Valley and includes about 14 square miles north and east of Manti, Utah. The mountainous area on the east side of Sanpete Valley is the Wasatch Plateau. The main structure in this area is the Wasatch monocline. In the Manti Canyon area, five recognizable formations are present. In ascending order, these are the North Horn, Flagstaff, Colton, Green River, and Crazy Hollow Formations. The area was a site of lacustrine and fluviatile deposition during the Upper Cretaceous and Lower Paleocene, floodplain and channel deposits during the lower Eocene and shallow lake deposits during later Eocene time. Deposition of the Crazy Hollow Formation occurred probably in the late Eocene and was followed by orogeny, normal faulting, and formation of the Wasatch monocline. Today the area is one of erosion and downslope movements.
