1974 Map of Skalkaho Pass

About this map

The Skalkaho Pass serves as the topographic and administrative divide on this 1974 survey, marking the boundary where the Bitterroot National Forest meets the Deerlodge National Forest. This high-elevation terrain is defined by a dense network of seasonal and perennial waters, including Hog Trough Creek and Railroad Creek to the west, and the North Fork Rock Cr draining toward Mud Lake in the northeast. The presence of Prospects near Daly Creek hints at the mineral exploration common to this portion of the Ravalli and Granite County line. Traversing this landscape required a reliance on established infrastructure like the Pack Trail, which connects remote landmarks such as Signal Rock and Camp Spring. The map captures a moment of mid-century forest management before modern developments further altered the drainage basins of the Sapphire Mountains.
