1986 Map of Mumbo Basin

USGS Topo · Published 1986

About this map

The Trinity Mountains dominate this high-elevation landscape within the Shasta National Forest, where the border between Siskiyou and Trinity counties follows the ridgeline of the Eddys. This mid-1980s provisional survey shows a wilderness defined by its complex drainage systems and subalpine lakes, including Gumboot Lake, Picayune Lake, and the remote Mumbo Lake at the head of Mumbo Basin.
