1986 Map of Seven Lakes Basin

About this map

Shasta National Forest dominates this mid-1980s landscape at the intersection of Siskiyou, Shasta, and Trinity counties. The high-elevation terrain is defined by the headwaters of major northern California waterways, including the South Fork Sacramento River and the East Fork Trinity River. The network of alpine waters is particularly dense within the Seven Lakes Basin, which features clusters like Upper Seven Lake and Lower Seven Lake.
