Mount Morrison is an 11367adj=midNaNadj=mid mountain summit located in Custer County, Idaho, United States.
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.[1] 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,[2] 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 5000abbr=offNaNabbr=off 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.[1] His calculations in 1929 discovered that an unnamed peak (which would become Borah Peak) was the highest in the state.[5]
Based on the Köppen climate classification, Mount Morrison is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.[6] Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.
