About this map

Gold-bearing ravines and high ridges define this landscape where the boundaries of Plumas Co Sierra Co meet. The area’s hydraulic and placer mining legacy is visible through a complex network of ditches and remnants like the Pioneer Mine Placer Diggings and the Thistle Shaft (Site). Settlements such as Gibsonville and Howland Flat occupy the high ground between deep drainages like Canyon Creek and Slate Creek, reflecting a settlement pattern dictated by the geology of the Mother Lode's northern reaches.

Modern recreation and forest management center around the Little Grass Valley Reservoir, with the La Porte Guard Station and USFS Admin Site serving as operational hubs for the surrounding Plumas National Forest. Small, scattered cemeteries like La Porte Cem and St Louis Cem provide genealogical anchor points for researchers tracing the families who once worked the Woods Mine or lived in vanished mining camps like Wahoo.
