About this map

Big Hole Pass marks a critical divide in this high-altitude landscape of Beaverhead County, where the drainages of the Bitterroot and Pioneer ranges meet. The terrain is defined by a dense network of mountain waterways, including the headwaters of Ruby Creek, Pioneer Creek, and Dahlonega Creek. Significant elevations like Morgan Mountain overlook complex topographical features such as Thompson Gulch and Bradley Gulch.

Transport through this isolated region is primarily limited to rugged corridors like Dahlonega Creek Rd, reflecting the area's primary use for resource management and wilderness access. Small alpine bodies of water, such as Morgan Jones Lake, are scattered among the steep ridges. This 2011 survey provides a clear view of the hydrological patterns of the Continental Divide, where streams like Nez Perce Creek and West Fork Nez Perce Creek carve through the mountain front.
