1910 Map of Todd Lakes

About this map

Fort Peck Indian Reservation lands dominate this 1910 survey of Northeastern Montana, a landscape defined by an intricate network of coulees and creek beds. The drainage systems of Wolf Creek and Little Porcupine Creek create a deeply dissected terrain, where the West Fork, Middle Fork, and East Fork Wolf Creek converge. The topography reveals a transition from the broad Tule Valley in the east toward the high, broken benches further west. A notable geographic concentration of water appears at Todd Lakes, providing a rare natural basin in this otherwise arid, high-plains environment. Surveyed by the U.S. Geological Survey and the General Land Office, the map also identifies the Valley Co Sheridan Co boundary line as it existed before subsequent county reorganizations in the region.
