1993 Map of Dearborn River

About this map

The Lewis and Clark Range dominates this 1993 study of the Montana high country, where the Continental Divide winds between the Scapegoat Wilderness and the Bob Marshall Wilderness. This area represents a massive protected landscape at the convergence of the Lewis and Clark National Forest, the Helena National Forest, and the Lolo National Forest. While the western portion is defined by peaks like Red Mountain and Silver King Mountain, the eastern section transitions into the high plains and ranching country around Augusta. Evidence of the region's wilderness management and recreational infrastructure is clear through the path of the Continental Divide Trail and the presence of the Blackfoot-Clearwater State Wildlife Management Area. Water resources are a central feature, from the headwaters of the Dearborn River and Landers Fork to the Nilan Reservoir and the glacial Bean Lake.
