1962 Map of Johnson Mountain

About this map

The Dearborn River carves through this high-altitude landscape in Lewis and Clark County, defining a territory where ranching and mountain geography converge. The northern portion of the map centers on the Steinbach Ranch, situated near the confluence of Big Skunk Creek and the main river channel. Water management in this arid environment is evidenced by the Gillette Ditch, which traverses the hillsides above the Middle Fork Dearborn River. To the south, the terrain rises sharply toward Johnson Mountain and Joes Mountain, while the Rogers Pass Section House marks a vital operational point for travelers or rail-related maintenance near the mountain crossing. Distinctive peaks like Sunset Hill and Sunrise Hill provide clear topographical landmarks in a region characterized by numerous named drainages, including Hardgrove Creek and Bedrock Creek.
