Wilbur Springs serves as the focal point of this northern California landscape, where the rugged intersections of Lake and Colusa Counties meet along County Line Ridge. The terrain is defined by a complex network of canyons and gulches, including the colorfully named Glory Hole Gulch and Schoolhouse Canyon, which suggest a history of early prospecting and local settlement. Prominent heights like Coyote Peak and Blue Ridge overlook the winding courses of Bear Cr and Sulphur Cr, water sources that likely dictated the placement of early homesteads.
