About this map

Cisco Grove and the surrounding high Sierra Nevada landscape are defined by a complex network of alpine reservoirs and the historic transportation corridor of the S Yuba River. This survey captures the region's hydraulic history, showing large-scale water management features like Lake Spaulding, Fordyce Lake, and the Lake Valley Reservoir. These bodies of water, connected by rugged drainages such as Fordyce Cr and the N Fork North Fork American River, were foundational to California's early mining and hydroelectric development.

Transportation through the mountains follows the natural contours of the land, with Yuba Pass and Yuba Gap serving as critical transit points. Small settlements and waypoints like Big Bend, Rainbow, and Crystal Lake line the primary route, while the interior is dotted with prominent peaks like Old Man Mtn and Signal Peak. The map provides an essential record of the Tahoe National Forest backcountry, detailing access roads like the Grouse Ridge Trl and Fordyce Lake Rd that serve both utility and recreation.
