1948 Map of American House

About this map

Mooreville Ridge and Harrison Ridge dominate this section of the Plumas National Forest, where steep canyons are carved by the Middle Fork Feather River and South Fork Feather River. The settlement pattern centers on remote mountain outposts and industrial sites, including the American House locality and the family-owned McIntosh Ranch and Boehme Ranch. A mid-century infrastructure shift is visible in the presence of the Little Grass Valley Res, which sits near the headwaters of the South Fork Feather River. Mining history is preserved through labels for the Browns Hill Mine and Sanborn Mine, while the high peaks are punctuated by fire detection sites such as Camel Pk Lookout and Lexington Hill Lookout. This landscape reflects the transition from early gold-seeking ventures to modern water resource management and forest service oversight.
