Sunset Peak is a 10201abbr=offNaNabbr=off summit in Park County, Montana, United States.
Sunset Peak is located 3.75miles northwest of Cooke City, Montana, in the Absaroka Range which is a subrange of the Rocky Mountains. It is set in the northeast corner of Yellowstone National Park on the common boundary shared by the park and Custer-Gallatin National Forest.[2] Precipitation runoff from the mountain's north slope drains into headwaters of the Stillwater River, whereas the southwest slope drains into Pebble Creek and the southeast slope drains into headwaters of Sheep Creek which are both part of the Lamar River watershed. Topographic relief is significant as the summit rises 1600abbr=offNaNabbr=off above each of the three streams in 1miles. The mountain's toponym has been officially adopted by the United States Board on Geographic Names,[1] and has been featured in publications since at least 1901.[4]
Based on the Köppen climate classification, Sunset Peak is located in a subarctic climate zone characterized by long, usually very cold, snowy winters, and mild summers.[6] Winter temperatures can drop below 0 °F with wind chill factors below −10 °F.
