Miller Mountain is a 10494abbr=offNaNabbr=off summit in Park County, Montana, United States.
Miller Mountain is located 2.85miles northwest of Cooke City, Montana, in the Beartooth Mountains which are a subrange of the Rocky Mountains.[1] It is set within the New World Mining District and the Custer-Gallatin National Forest.[2] Precipitation runoff from the mountain's north slope drains into headwaters of the Stillwater River, whereas the south slope drains into Sheep Creek → Soda Butte Creek → Lamar River. Topographic relief is significant as the summit rises 2000abbr=offNaNabbr=off above Sheep Creek in 1miles. The mountain is composed of gabbro, Miocene breccia, and Eocene monzonite porphyry.[4] The mountain's toponym has been officially adopted by the United States Board on Geographic Names,[3] and has been featured in publications since at least 1911.[5] The mountain is named after Adam "Horn" Miller (1839–1913), who was one of the four trappers who discovered and named the New World Mining District in 1869, with the others being Bart Henderson, J. H. Moore, and James Gourley.[6] [7] Adam Miller staked a claim that he called Shoo Fly Mine at the 9,300-foot-elevation level on the south slope of this mountain which would bear his name.[6] [8] From 1878 through the late 1880s, the Shoo Fly produced gold, copper, and lead-silver ore, but it closed in 1893 to never reopen.[8] (Henderson Mountain is 1.61miles east-northeast of Miller Mountain).[1]
Based on the Köppen climate classification, Miller Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and mild summers.[9] Winter temperatures can drop below 0 °F with wind chill factors below −10 °F.
