Cutoff Mountain is a 10695abbr=offNaNabbr=off mountain summit located in Park County, Montana.[3]
Cutoff Mountain is located in the Absaroka Range, which is a subset of the Rocky Mountains. It is situated in the Absaroka-Beartooth Wilderness, along the Yellowstone National Park boundary, on land managed by Gallatin National Forest. Precipitation runoff from the mountain drains into tributaries of the Lamar River, which in turn is a tributary of the Yellowstone River. Topographic relief is significant as the southeast aspect rises 2800abbr=offNaNabbr=off above Pebble Creek in 1.5 mile. This geographical feature was originally named Cutoff Peak in 1929, and the Cutoff Mountain name was officially adopted in 1969 by the United States Board on Geographic Names.[3]
Based on the Köppen climate classification, Cutoff Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and mild summers.[4] Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.
