Henderson Mountain is a 10,343-foot (3,153-metre) summit in Park County, Montana, United States.
Henderson Mountain is located 2.4 miles (3.9 km) north 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 Fisher Creek which is a tributary of the Clarks Fork Yellowstone River, whereas the south slope drains into Miller Creek → Soda Butte Creek → Lamar River. Topographic relief is significant as the summit rises nearly 1,400 feet (427 meters) above Fisher Creek in 0.6 miles (0.97 km). The mountain is a laccolith composed of Cambrian limestone, breccia, and Eocene dacite porphyry. [4] [5] Gold was discovered on Henderson Mountain in 1888. [4] In the mid-1990s, Henderson Mountain was the epicenter of legal fighting over plans to mine a billion dollars' worth of gold and silver from the mountain which would threaten nearby Yellowstone National Park. [6] The environmental controversy ended when the US government bought out the mining claim. [7] 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 1893. [8] Bart Henderson was one of the four trappers who discovered the New World Mining District in 1869, with the others being Adam Miller, J. H. Moore, and James Gourley. [9] (Miller Mountain is 1.61 miles (2.59 km) west-southwest of Henderson Mountain). [1]
