About this map

Deer Lodge and Beaverhead counties meet along a high mountain divide in this early 1960s survey, where the Deerlodge and Beaverhead national forests converge. The landscape is defined by the headwaters of the Big Hole River, which winds through the southern portion of the map. Man-made water management is evident through the presence of the Bacon Ditch and Anderson Ditch, suggesting a history of agricultural or industrial water diversion in this high-altitude terrain.

Remote outposts like the La Marche Creek Ranch and Sportsmans Campground provide the only significant markers of human habitation amidst a network of drainages including Seymour Creek and Chub Creek. The map meticulously details a system of pack trails and jeep trails that navigate the slopes surrounding Lower Seymour Lake, offering a window into the mid-century recreational and ranching access patterns of southwest Montana.
