1978 Map of Dennis Mtn

USGS Topo · Published 1978

About this map

Nezperce National Forest and the Bitterroot National Forest converge in this high-altitude landscape within Idaho County, documented in the late 1970s. The area is defined by the Salmon River Breaks Primitive Area, a terrain of steep drainages and prominent peaks like Dennis Mtn and Harrington Mtn. The map shows a network of named watercourses, including Sabe Creek, Harrington Creek, and Saddle Creek, which carve deep into the surrounding ridges. Remote landmarks such as Cabin Spring and the Dennis Lakes suggest the isolated nature of this wilderness. A series of routes, labeled simply as Pack Trail or Trail, provide the only access across features like Black Creek Saddle and Harrington Saddle. This survey captures the region's character as a protected, undeveloped corridor before modern changes in forest management and wilderness designations.
