About this map

The Big Hole River flows across the southern edge of this landscape, marking the boundary between Deer Lodge and Beaverhead Counties. This high-altitude region is defined by its complex water management and protected lands, featuring the Mt Haggin Wildlife Management Area and the Anaconda-Pintler Wilderness. Early ranching and irrigation history is evident through the presence of the La Marche Creek Ranch and engineered water systems like Bacon Ditch and Anderson Ditch.

A network of drainage systems including Seymour Creek and Chub Creek feed into the river valley from the surrounding Deerlodge National Forest and Beaverhead National Forest. Significant backcountry access is charted via numerous pack trails and a jeep trail leading toward Seymour Lake. Along the river, the Sportsmans Campground and several benchmarks, such as BM 5800, provide fixed points for navigating this forest and river terrain.
