The Scott Valley and the high ridges of the Shasta National Forest define this 1931 survey of Northern California. The landscape is a complex network of industrial extraction and high-mountain settlement, anchored by the towns of Etna and Callahan. The southern portion of the sheet reveals an intensive mining history, particularly along the boundary of Siskiyou and Trinity Counties, where the Bonanza King Mine and Altoona Mine were situated near the headwaters of the Trinity River.
