O'Sullivan Peak (Utah)

O'Sullivan Peak, also known as Sunrise Peak, is an 11275 ft mountain summit located in Salt Lake County, Utah, United States.

Description
O'Sullivan Peak is located 15 mi southeast of downtown Salt Lake City in the Twin Peaks Wilderness on land managed by Wasatch–Cache National Forest. The peak is set in the Wasatch Range which is a subset of the Rocky Mountains. Precipitation runoff from the mountain's south slope drains to Little Cottonwood Creek, whereas the north slope drains to Big Cottonwood Creek, and both creeks flow west to the Jordan River. Topographic relief is significant as the summit rises 4475 ft above Little Cottonwood Canyon in 1.4 mile (2.25 km). This mountain's toponym was officially adopted in 1978 by the United States Board on Geographic Names to remember Timothy H. O'Sullivan (1840–1882), civil war and western frontier photographer who visited this area as the official photographer of the King Survey and Wheeler Survey.
