1968 Map of Spur Mountain

About this map

The Snowcrest Range dominates this late 1960s survey of Madison County, showing the high-altitude terrain within the Beaverhead National Forest. This interior mountain landscape is defined by the drainage systems of the West Fork Ruby River and the main Ruby River, which gather water from numerous creeks like Ledford Creek and Hole Creek. The map documents a wilderness environment where human passage is marked primarily by the Snowcrest Trail and Gilbert Trail. Notable peaks such as Spur Mountain, Sliderock Mountain, and Snowcrest Mtn anchor the topography, while the Centennial Divide runs through the southeastern corner. A small glacial feature, Yellow Bear Lake, sits high in the western ridges below Hogback Mountain, illustrating the remote character of this Montana high country.
