1969 Map of Blocksburg

USGS Topo · Published 1974

About this map

Blocksburg serves as the primary upland settlement on this 1969 survey, situated amidst the complex ridges of southern Humboldt County. The landscape is defined by the steep descent toward the Eel River, which snakes through the western portion of the quadrangle. Parallel to the river's course, the Northwestern Pacific River railroad line follows the narrow valley floor, passing through Eel Rock and near Oak Glen. This corridor represents the critical transport link for the region's timber and ranching economy during the late 1960s.
