2012 Map of Challenge

About this map

The northern Sierra Nevada foothills are defined by the winding waters of the New Bullards Bar Reservoir and the deep drainage of the N Yuba River in this 2012 survey. Centered around the communities of Challenge and Sharon Valley, the landscape is a mix of forest management and legacy ranching. Settlement patterns are concentrated along the historical La Porte Rd corridor, where the Post Office serves as a central landmark for the surrounding heights of Pike County Peak and Empire Ridge. The map reveals the extensive network of forest service roads and logging routes that navigate the complex terrain of the Oregon Hills and Fountain House Hill. To the south, the Yuba County Forestry Headquarter near Frenchtown anchors the local timber and land management economy, while various family-named holdings like Whitehead Ranch and Girot Ranch dot the more accessible ridges.
