About this map

Chessman Reservoir serves as a central hydrological feature within this high-elevation landscape straddling the boundary between Lewis and Clark and Jefferson counties. The terrain is defined by a series of prominent peaks and basins, including Lava Mtn and the sprawling Occidental Plateau, which transition into the protected lands of the Helena National Forest and Deerlodge National Forest.

Evidence of the region's geographic complexity is found in the numerous gulches and meadows that have historically supported local activity, such as Frohner Meadows and Lump Gulch. The map captures a detailed network of watercourses like Tenmile Cr and N Fork Quartz Cr that carve through the mountain passes. Access to these remote areas is facilitated by high-clearance routes like Chessman Rd and Corral Gulch Rd, highlighting the area's continued use for forest management and back-country recreation.
