Lonesome Mountain is an 11,399-foot (3,474-metre) mountain summit located in Carbon County, Montana. ^[3]

Description

Lonesome Mountain is located in the Beartooth Mountains, which are a subset of the Rocky Mountains. It is situated 4.2 miles north of Beartooth Butte in the Absaroka-Beartooth Wilderness, on land managed by Gallatin National Forest. The highest point in Montana, Granite Peak, rises 14.3 miles to the northwest. Precipitation runoff from the mountain drains into several surrounding alpine lakes which feed tributaries of the Clarks Fork Yellowstone River. Topographic relief is significant as the summit rises 1,400 feet (430 meters) above these lakes in less than one mile. This geographical feature's name has been officially adopted by the United States Board on Geographic Names. ^[3]
