The John Long Mountains el. 7923 feet (2415 m) is a small mountain range northwest of Philipsburg Montana in Granite County Montana. The Beaverhead-Deerlodge National Forest and Lolo National Forest manage these mountains. A sizable roadless area of about 65000 acres existed as of 1990 in the John Long Mountains centered on Silver King Mountain in the southern part of the range. It’s unknown whether and to what extent this area’s size has been reduced by logging.
