1950 Map of Sphinx Mountain

USGS Topo · Published 1968

About this map

The Gallatin River valley and the high divides of the Gallatin National Forest define this 1950s survey area. The landscape is marked by a network of remote outposts and working land, from the Nine Quarter Circle Ranch near Lincoln Mountain to the high-elevation Big Spring Ranger Sta. Geographically, the sheet covers the rugged transition where the Beaverhead National Forest meets the Gallatin, featuring prominent peaks like the Sphinx Mtn and The Helmet. The presence of several administrative stations, including the Yellow Mule Ranger Sta and Cache Creek Ranger Sta, reflects the mid-century management of these protected timberlands and watersheds. Researchers can trace historic access routes like the Ditch Trail and Eldridge Trail which connected isolated camps such as Manley Camp to the more developed ranching clusters in the northeast corner.
