About this map

Challenge and Sharon Valley occupy a high-elevation corridor in the northern Sierra foothills, where the Plumas National Forest and Tahoe National Forest meet. The landscape is defined by the steep drainage basins of Indian Cr and the New Bullards Bar Reservoir, which occupies the eastern edge of the quadrangle. Several small settlements including Greenville and Fountain House are connected by mountain thoroughfares like Marysville Rd and La Porte Rd.

The terrain reveals numerous bars and points along the river canyons, such as Sucker Bar and Rock Island Bar, reflecting a history of river-based activity. Prominent summits like Pike County Peak and Oregon Peak overlook the deep ravines of Rich Gulch and Garden Valley, while numerous winding roads such as Fountain House Rd and Slate Rd trace the ridgelines and creek beds through the heavily timbered mountain slopes.
