1961 Map of Coburn Mountain

About this map

The Dearborn River cuts through this landscape along the boundary of Lewis And Clark Co and Cascade Co, defining a region shaped by ranching and mountain geography. Settlers and ranch hands at the Dearborn Ranch lived in the shadow of prominent peaks like Elephant Mountain and Coburn Mountain. The map reveals the infrastructure of early mid-century rural life, including the Sevenmile Sch located along Sevenmile Road and the Dearborn Cem situated near a small Mine. Water management and transportation are central to the area's development, evidenced by the Pumping Station, a Gaging Sta on the river, and the long Pipeline that traverses the terrain near Flat Creek Road. The presence of The Reef and numerous coulees like Twin Bridge Coulee illustrates the complex drainage patterns of this high-country terrain.
