1952 Map of Duncan Peak

USGS Topo · Published 1976

About this map

Whisky Hill and the surrounding drainages of the North Fork American River define this mid-century topographic portrait of Placer County gold country. The map documents an intensive historical mining landscape within the Tahoe National Forest, where the complex water systems of the Iowa Hill Ditch supported operations across steep ridges. Significant industrial remnants are recorded through numerous subterranean features, including the Union Tunnel, Hungry Hollow Tunnel, and Macedon Tunnel.
