Boulder Baldy and Boulder Mtn anchor this high-elevation landscape within the Helena National Forest, marking the rugged boundary between Meagher and Broadwater Counties. The map details a complex drainage system where the headwaters of Confederate Gulch and Blacktail Creek flow through deep ravines like Debauch Gulch and Irish Gulch. A network of primitive routes and footpaths, including the Belt Mountain Divide Trl and Boulder Lakes Trl, provides access to remote alpine features such as Boulder Lakes and Camas Lake. The terrain is defined by sharp elevation changes, particularly along the Camas Ridge and the descent into the Middle Fork Big Camas Creek valley, illustrating the wilderness character of the Big Belt Mountains in the modern era.
