2011 Map of Chamberlain Mountain

About this map

The Blackfoot River flows along the northern edge of this high-country survey in Powell County, marking a landscape defined by prominent peaks and vital water management. Four significant peaks—Chamberlain Mountain, Granite Mountain, Green Mountain, and Dunigan Mountain—anchor the central and western terrain. The eastern portion of the map is notable for its water infrastructure, including the Wales Creek Reservoir and its associated Wales Creek Reservoir Dam, along with the series of structures at Raymond Dam, Raymond Number 2 Dam, and Raymond Number 3 Dam. This network of reservoirs suggests a landscape managed for irrigation or livestock in the Montana ranching tradition. Access into this high-elevation area is maintained via several Bureau of Land Management routes, such as BLM Road 2801 and BLM Road 2809, which follow the drainages of Pearson Creek and East Fork Chamberlain Creek.
