1961 Map of Alturas

About this map

Alturas serves as the focal point of this Modoc County survey, situated at the confluence of the Pit River and its South Fork Pit River. The town's infrastructure in the early 1960s is detailed, including the courthouse, Municipal Airport, and the Southern Pacific railroad line through Lakeview Junc. To the south, the Modoc National Wildlife Refuge encompasses a network of wetlands and weirs along the river's path. Historical depth is provided by the Infernal Caverns Battleground Memorial Marker and the nearby Infernal Caverns Ruins in the southern hills, commemorating conflict on the frontier. The landscape transitions from the agricultural Warm Springs Valley and its many reservoirs, like Graves Reservoir, to the timbered heights of the Modoc National Forest, where features such as Graven Ridge and Rocky Prairie define the high country.
