2014 Map of Coburn Mountain

About this map

The Dearborn River snakes through this high-plains landscape on the border of Lewis and Clark and Cascade counties. The area is characterized by dramatic elevation changes, from the prominent heights of Coburn Mtn and Elephant Mtn to the deeply carved drainage of Dead Man Coulee. Human presence is marked by ranching infrastructure and remote air transit at the Bar E Airport, while the Dearborn Crossing Cem serves as a silent witness to the early settlers who navigated this river crossing. Long-established routes like Birdtail Rd and Sevenmile Rd follow the natural contours of the land, connecting isolated ranching operations. The presence of the Hultine Ditch and the Sullivan Cr suggests a landscape defined by the management of water in an arid environment, where even seasonal flows dictate the placement of roads and homesteads.
