2024 Map of Sun River

About this map

Sun River is the central lifeblood of this Montana landscape, where the river's meandering course is shadowed by an extensive network of irrigation infrastructure essential to the region's agricultural character. This modern topographical survey details the intricate water management system, including the Sun River Valley Ditch, Greenfield South Canal, and Canal K, which serve the high plains terrain above the river valley. The map clearly delineates the plateau formations of First Bench and Ashuelot Bench, which rise above the river's floodplain. The settlement of Sun River itself is anchored by a Po and the nearby Sun River Cem, serving as the local hub for a network of rural roads such as Sun River Cascade Rd and Adams Rd. To the north, the boundary between Teton Co and Cascade Co follows section lines through a landscape etched by smaller drainages like Mill Coulee Creek and Muddy Creek.
