About this map

The northern reaches of the Lewis and Clark National Forest dominate the lower half of this landscape, rising to the high point of Peterson Mountain and the distinctive geological formation known as The Arch. The terrain is defined by a series of north-draining coulees, including Jackson Coulee, Shannon Coulee, and Chambers Coulee, which cut through the high country toward the drainage of Big Otter Creek.

Evidence of local resource extraction is visible through the Chambers Mine and a Gravel Pit, while a prominent Pipeline and a network of jeep trails traverse the uplands between McCarthy Creek and Old Geysey Creek. This map captures a specialized mountain environment where the sharp relief of the coulees dictates the placement of early transportation routes and small-scale mining operations during the mid-twentieth century.
