2017 Map of Racetrack

About this map

Racetrack and its surrounding ranchlands sit at the intersection of a complex irrigation network and historical travel corridors. This 2017 survey details the intensive water management required in this Montana landscape, where the Morrison Ditch, W. Side Canal, and various mountain-fed streams like Dempsey Cr and Racetrack Cr sustain the valley floor. The geography is defined by the transition from the high Morrison Gulch and Powell Reservoirs down to the Clark Fork river. The map documents the persistent layout of the Yellowstone Trl, a historic highway route that parallels the modern infrastructure. Along the boundary of the Powell Co Deer Lodge Co line, the grid of secondary roads like Dempsey Lake Rd and Upper Racetrack Rd provides a clear view of how land ownership and access are structured around the natural drainage of Modesty Cr and the larger valley floor.
