Sheep Mountain is a 10097abbr=offNaNabbr=off mountain summit in Park County, Montana, United States.
Sheep Mountain is located 39miles south of Bozeman in the Gallatin Range, which is a subrange of the Rocky Mountains.[1] It is set on the common boundary shared by Yellowstone National Park and the Gallatin National Forest. The mountain is also within the Gallatin Petrified Forest which is one of the largest petrified forests of the Eocene Epoch. Precipitation runoff from the mountain's north slope drains to the Yellowstone River via Tom Miner Creek, whereas the south slope drains to Specimen Creek which is a tributary of the nearby Gallatin River. Topographic relief is significant as the summit rises approximately 1800abbr=offNaNabbr=off above headwaters of North Fork Specimen Creek in 1miles. The approach to the remote summit is made from the Sky Rim Trail and Gallatin Skyline Trail.[4] There is a microwave reflector stationed at the summit. The mountain's toponym has been officially adopted by the United States Board on Geographic Names.[3] This peak should not be confused with the other Sheep Mountain also in Park County, Montana, but in the Absaroka Range.
Based on the Köppen climate classification, Sheep Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and mild summers.[5] Winter temperatures can drop below 0 °F with wind chill factors below −10 °F.
