About this map

The Continental Divide defines the spine of this high-elevation landscape, where the headwaters of the Little Blackfoot River emerge within the protected lands of the Helena National Forest and Deerlodge National Forest. This 2017 survey details the complex topography of the Powell and Jefferson County line, revealing a network of drainages such as Monarch Cr and Ontario Cr that carve through the surrounding peaks.

Mining and early exploration history is evident in the naming of features like Irish Mine Hill and Treasure Mtn, suggesting a legacy of prospecting in these mountains. Notable landmarks such as Blackfoot Meadows and Limburger Spring provide specific points of reference for those studying the area's natural history or tracing old forest routes like Little Blackfoot River Rd. The terrain is marked by prominent ridges and gulches, including the steeply pitched Forbidding Ridge and the aptly named Moose Gulch.
