About this map

The boundary between the Blackfeet Indian Reservation and the Lewis and Clark National Forest bisects this landscape, marking a transition from high mountain peaks to the rolling foothills of the Rocky Mountain Front. Dominating the western edge is the Swift Reservoir, controlled by the Swift Dam and its adjacent Spillway. The presence of the Fish Lake Sch near the central drainage of Fish Lake suggests a sparse but established ranching community during the late 1960s.

A network of water systems, including Birch Creek and Sheep Creek, defines the local topography, which rises sharply to Split Mountain in the south. These waters are fed by remote sources like Hell Roaring Spring and high-elevation basins such as Green Lake. The map details a landscape managed for both timber and water, crisscrossed by a Jeep Trail and a Back Trail, providing a clear record of land use and resource management before modern developments.
