About this map

Bean Lake sits at the heart of this landscape, where the plains meet the rising foothills of the Lewis and Clark Range. The map documents a ranching-heavy corridor along the Dearborn River, evidenced by family-named properties like White Ranch, Mosher Ranch, and the Diamond Bar X Ranch. Water management is the dominant human imprint on the land, with an intricate network of irrigation features including the Dearborn Canal, Mosher Ditch, and Cunniff Ditch designed to move water from the river to the drier flats.

Within the Lewis and Clark National Forest, the terrain shifts abruptly into rugged basins and gulches. Named features such as Harrison Basin, Pole Gulch, and the prominent Table Mtn define the western reaches of the quadrangle. This 1990s survey, based on updated aerial photography, provides a clear record of the enduring ranching boundaries and the sophisticated water systems that sustain the eastern edge of the Lewis and Clark County high country.
