About this map

The Lewis and Clark Trail cuts across the northern expanse of this 1968 survey, tracing a path through the high plains of Glacier County. The landscape is defined by the complex water management systems of the Blackfeet Indian Reservation, centered on the Main Two Medicine Canal and the Two Medicine River. These waterways supported the sprawling agricultural terraces of Seville Flat and Hagan Flat, where the irrigation network transformed the arid terrain.

Prominent natural landmarks like Mission Lake and the distinctive Squaw Buttes provide vertical relief in an otherwise expansive flatland. Smaller water sources, including Carlow Lake, Kimble Spring, and Spring Creek, are vital features for local history and genealogy research, marking the locations of early water rights and land use. The map also captures the varied topography of Spring Coulee, illustrating the natural drainage patterns that run through this section of the Montana prairie.
