1977 Map of Mussigbrod Lake

About this map

The Continental Divide crests along the Bitterroot Range, forming the high boundary between Ravalli and Beaverhead Counties. This high-elevation wilderness is defined by its network of glacial lakes and the primitive transportation routes used to access them, including the Continental Divide Pack Trail. Notable water bodies like Mussigbrod Lake, Hope Lake, and Mystic Lake feed the headwaters of Plimpton Creek and Mussigbrod Creek. Human activity in this remote region is marked by utilitarian outposts such as a Forest Service Station, a Campground, and a lone Corral in the southern reaches. The map details a landscape transition where the protected Anaconda Pintler Wilderness meets the working lands of the Beaverhead National Forest, preserving the 1970s character of Montana's backcountry before modern developments altered high-country access.
