Tenmile Peak is set west of the Continental Divide in the Tenmile Range which is a subrange of the Rocky Mountains. The mountain is located southwest of the community of Frisco and is set on land managed by Arapaho National Forest. The Continental Divide Trail traverses the east slope of the peak and Interstate 70 runs along the western base of the peak. Precipitation runoff from the mountain's west slope drains into Tenmile Creek and the east slope drains to Miners Creek, which both empty into Dillon Reservoir. Topographic relief is significant as the summit rises above Tenmile Creek in one mile (1.6 km). The mountain's toponym has been officially adopted by the United States Board on Geographic Names, and has been recorded in publications since at least 1906.Henry Gannett, United States Geological Survey (1906), A Gazetteer of Colorado, US Government Printing Office, p. 167.
