About this map

Sun River sits at the heart of this landscape, where the namesake waterway winds eastward through a complex network of agricultural irrigation infrastructure. The map documents an intricate system of water management essential to the region's ranching and farming, including the Sun River-Valley-Ditch, Greenfield S Canal, and GS 51 Ditch. These man-made channels parallel the natural courses of Mill Coulee Cr and Muddy Creek, illustrating the extensive modification of the drainage basins between Teton and Cascade Counties.

Elevated terrain features like First Bench and Ashuelot Bench provide clear topographical markers above the river valley. For local historians and genealogists, the Sun River Cem and the central settlement of Sun River serve as primary anchors for tracing family roots in this part of Montana. The road network, featuring names like Dracut Hill Rd and Open Buckle Rd, reflects the rural development and land divisions that define the area's modern character.
