2018 Map of American House

About this map

American House serves as a central reference point in this high-elevation corner of the Plumas National Forest, where the complex headwaters of the Feather River system carve through the Sierra Nevada. The terrain is defined by prominent divides such as Mooreville Ridge and Lumpkin Ridge, which separate various drainages including the South Branch Middle Fork Feather River and the South Fork Feather River. Evidence of the region’s long-standing mining history is visible at the Wolters Mine and Polaris, along with various access routes like the Quincy La Porte Road. To the northeast, the Little Grass Valley Reservoir marks a significant water management feature, while landmarks like Lexington Hill and Diamond Springs Hill highlight the varied topography that once drew prospectors and timber crews to this transition zone between Butte, Plumas, Yuba, and Sierra counties.
