About this map

Eldorado National Forest defines the character of this landscape along the border of El Dorado and Placer counties. The small settlement of Quintette serves as a focal point in a region dominated by steep drainage systems and high ridges. The map meticulously traces the course of the Rubicon River and its numerous tributaries, including Pilot Creek and Rock Creek, which have carved deep canyons like Missouri Canyon and Bacon Canyon through the timbered terrain.

Evidence of early water management and pioneer history is visible in features like the Georgetown Divide Ditch and the Pioneer Graves Cem. A network of historic forest routes, including the Volcanoville Road and Wentworth Springs Road, provides access to high points such as Pennsylvania Point and Lynchburg Hill. These topographic details illustrate a mountain economy transitioning from early resource extraction to managed forest lands and rural residency.
