1973 Map of White Rock Peak

About this map

The South Fork Salmon River carves through a deep canyon corridor in this 1973 survey, acting as the primary artery for travel and recreation between the Payette National Forest and the Boise National Forest. The map documents a landscape defined by dramatic elevation changes, from the riverside flats where Poverty Flat Campground and Lodgepole Campground are situated, up to the high prominence of White Rock Peak. A single Pack Trail provides the primary overland access through the steep drainages of Blackmare Creek and Silver Creek. Of particular interest to those studying local hydrology is the isolated Spring (Hot) located near Goat Creek, suggesting the geothermal activity prevalent in this part of the Idaho batholith. The boundary between the two national forests is clearly delineated, following the high ridges that separate these vast timber and watershed reserves.
