About this map

Lewis and Clark National Forest encompasses this high-altitude landscape in the Little Belt Mountains as it appeared in the early 1960s. The map highlights a series of prominent summits and ridges, including the namesake Yogo Peak, Big Baldy Mountain, and the massive Prospect Ridge that dominates the southeastern quadrant. Evidence of the region’s long-standing mining history is visible at the Neihart No 2 site near the western boundary, while the surrounding terrain is carved by a dense network of gulches such as Gravel Gulch, Lyons Gulch, and Lead Gulch.

Navigation through this mountain terrain relied heavily on a system of remote paths, identified here as Pack Trail and Jeep Trail routes. These paths connect significant alpine landmarks like Twin Lakes and Lake Elva with distant points such as Coyote Peak and Slide Rock Point. The drainage patterns are well-defined by the headwaters of Yogo Creek and Jefferson Creek, illustrating the natural flow from the high peaks into the valley basins below.
