1995 Map of Challenge

USGS Topo · Published 1995

About this map

Oregon Hills define this corner of the northern Sierra foothills, where the New Bullards Bar Reservoir fills the deep canyons of the North Yuba River. This 1995 provisional survey illustrates a landscape managed by the Plumas National Forest and Tahoe National Forest, with a network of logging roads and forest service infrastructure like the Calif Dept of For Fire Sta. The map serves as a vital record for local history, showing family-named locations such as Baker Ranch, Burns Ranch, and Cummings Ranch alongside the historic Keystone Cemetery. These small holdings and settlements like Challenge and Greenville reflect the persistent human footprint in a region shaped by timber and water management, punctuated by engineering works like the New Bullards Bar Dam and the Colgate Tunnel.
