1979 Map of Mount Shasta

About this map

Mount Shasta dominates this northern California landscape, its massive volcanic profile surrounded by a complex network of canyons and high ridges in the late 1970s. The Southern Pacific railroad follows the winding corridor of the Sacramento River, passing through the communities of Dunsmuir, Shasta Springs, and Shasta Retreat. This corridor was essential for the timber and transit industries of the era, linking the mountain's base to the valley below. To the west, the steep peaks of the Trinity Mountains and the Scott Mountains offer a stark contrast to the volcanic debris of the Lava Natural Landmark to the northeast. Researchers can find historical resource extraction sites like the Integral Mine and Mumbo Mine, while the distinctive granite spires of Castle Crags stand as a permanent landmark above the river valley.
