Sheephorn Peak and Rocky Peak anchor this high-elevation landscape within the Salmon-Challis National Forest during the early 21st century. The map reveals a complex network of alpine drainages, where the Big Timber Creek and its tributaries, such as Rocky Creek and Alder Creek, carve through the mountainous terrain of Lemhi County. In the north, Milk Creek and the North Fork Little Timber Creek define the watershed patterns. Human presence is limited to remote access routes like the Swan Basin Rd and Big Timber Creek Rd, which provide passage into the Swan Basin. This survey documents the area's topographical character, from the prominence of Leadore Hill to the remote Junction Peak, providing a clear view of the wilderness before subsequent forest service management shifts or environmental changes.
