1969 Map of Grape Mtn

USGS Topo · Published 1977

About this map

Arrowrock Reservoir and the South Fork Boise River dominate this canyon-heavy landscape within the Boise National Forest as it appeared in the late 1960s. The survey captures the sharp topography around Grape Mtn and the unique landmark of Rock Pinnacle, where the river makes a dramatic westward turn. This is a region defined by its hydrology and drainage patterns, with numerous named gulches and creeks such as Nibbler Gulch, Soap Creek, and Deadman Creek feeding the larger river system.
