About this map

The Boulder River corridor serves as the primary axis for movement through this high-elevation mountain landscape, bridging the boundary between the Gallatin National Forest and Custer National Forest. The map documents a rugged network of drainage systems, where significant peaks like Chrome Mtn and Contact Mtn rise above glacial-carved terrain. Human presence is concentrated along the narrow valley floor, marked by the Main Boulder Rd and key crossings such as Twomile Bridge and Flemming Bridge.

Evidence of historical land use is visible in the presence of Placer Basin and the Speculator settlement area, suggesting the region's long-standing connection to resource extraction and high-country exploration. To the east, the East Boulder Plateau provides a high, relatively level contrast to the steep incisions of Wright Gulch and Lewis Gulch. The complex hydrography, including Great Falls Creek and Froze-to-Death Cr, illustrates the intricate watershed that defines this portion of the Beartooth region.
