2020 Map of Big Rock

About this map

The Two Medicine River and its tributary, the S Fork Two Medicine River, carve a complex drainage system through this portion of Glacier County. The landscape is defined by its transition from the plains toward the high peaks, with the eastern edge of the Sawtooth Range appearing in the southwest corner. Significant named landmarks include the distinctive Big Rock formation and a series of perennial waterways such as Deep Creek, Elk Creek, and Depot Creek. Human presence is marked by a network of rural routes including Morning Gun West Rd and the Heart Butte Cutoff, which facilitate travel through this isolated terrain. The map also identifies the specifically located 32N12W36ADCC01 Spring, an essential water source for local ranching and wildlife management.
