2017 Map of Skalkaho Pass

About this map

Skalkaho Pass serves as a critical divide in the southern Sapphire Mountains, marking the rugged boundary between Ravalli and Granite counties. This high-altitude drainage divide separates the waters of Skalkaho Cr, flowing west toward the Bitterroot Valley, from the headwaters of the Rock Creek system to the east. The landscape is defined by the convergence of two major federal landholdings, the Bitterroot National Forest and the Deerlodge National Forest. Navigational access through this mountain corridor is provided by the Skalkaho-Rye Rd 75, a route that traces the steep contours past landmarks like Signal Rock. Geologically and hydrologically focused, the map identifies numerous small tributaries such as Hog Trough Cr, Weasel Cr, and Bowles Cr, alongside high-elevation features like Mud Lake.
