Lolo National Forest dominates the northern and western reaches of this landscape on the border of Missoula and Powell Counties. The small settlement of Woodworth sits at a transition point where the high forest slopes meet the complex drainage systems that feed the Blackfoot River to the south. This 2017 survey reveals a network of roads shaped by the timber and ranching history of the region, including Logging Rd and Sperry Grade Rd. The topographical data shows how local geography is defined by significant creek valleys such as Black Canyon Cr and Cottonwood Cr. Private infrastructure like the Black Canyon Ranch Airport and the expansive Blanchard Flats reflect the modern land use patterns of this Montana mountain corridor, where resource management and rural residence intersect.
