1962 Map of Johnson Mountain

About this map

Dearborn River drainage systems define this landscape in Lewis and Clark County, where the terrain transitions from the river valley to prominent peaks. The early 1960s cattle ranching and infrastructure of this Montana high-country are visible at the Steinbach Ranch and the Rogers Pass Section House, reflecting the essential human footprint in a region dominated by relief. Water management for the area's dry mountain slopes is documented through the Gillette Ditch, which follows the contours of the Middle Fork Dearborn River. Significant elevations including Johnson Mountain, Joes Mountain, and the twin heights of Sunset Hill and Sunrise Hill provide landmarks for navigating the network of named drainages like Hardgrove Creek and Cuniff Creek.
