Walkerville and the northern reaches of Butte dominate the lower half of this landscape, where the urban grid meets the steep slopes of Steep Mtn. The transition from city to wilderness is stark, marked by the boundaries of the Deerlodge National Forest and the winding Continental Divide at the county line. The map captures a complex industrial and natural interface, showing numerous DNF (Do Not Fill) mine-related areas scattered through gulches like Beer Straight Gulch and Whiskey Gulch. Local infrastructure is prominent, from the Moulton Reservoir Number One to the dense street network of Centerville and Pioneer. The topography is defined by a succession of drainages such as Bull Run Cr and Yankee Doodle Creek, illustrating the challenging terrain that shaped the development of one of Montana's most significant mining districts.
