About this map

The North Fork Feather River carves a deep path through the canyon lands of the Lassen National Forest and Plumas National Forest. This 1950 survey highlights a period when the river was a corridor of industry and energy, featuring the Diversion Dam and Powerhouse at Las Plumas. The Western Pacific railroad tracks follow the river's winding course, connecting small settlements like Isaiah, New Blinzig, and Berry Creek Station.

Hard-rock mining legacies are scattered across the terrain, including the Hornet Mine, Evening Star Mine, and the inactive Treasure Hill Mine. Rural life is anchored by local institutions such as the Berry Creek Sch and Rockefeller Sch. The landscape is a complex mix of steep ridges like Big Ridge and Swayne Hill, intertwined with water features such as Madrone Lake and numerous creeks that feed the Feather River watershed.
