  Mount Morrison is an 11,367-foot elevation (3,465 m) mountain summit located in Custer County, Idaho, United States.
  
  ## Description
  
  Mount Morrison ranks as the 56th-highest peak in Idaho and is part of the Lost River Range which is a subset of the Rocky Mountains. The mountain is set on land managed by Salmon–Challis National Forest. Neighbors include White Cap Peak 2.6 miles southeast, line parent Mount Idaho, 1.2 mile east-northeast, and Borah Peak, the highest peak in Idaho, is 2.7 miles to the north-northeast. Precipitation runoff from the mountain's slopes drains to Big Lost River. Topographic relief is significant as the summit rises 5,000 feet (1,500 meters) above Thousand Springs Valley in 2.5 miles. This landform's unofficial toponym honors Lee Morrison, USGS topographer who mapped much of Idaho from 1924 through 1935. His calculations in 1929 discovered that an unnamed peak (which would become Borah Peak) was the highest in the state.
