1948 Map of Rackerby

About this map

Rackerby and Brownsville anchor this 1940s landscape where the gold-bearing terrain of Butte and Yuba counties meets the Plumas National Forest. The map documents a working rural economy defined by small-scale mining and ranching, featuring the Central Pacific Mine, Three-in-One Mine, and Madrone Mine. Water management is central to the area's development, evidenced by the Wyandotte Canal winding through the foothills. Local genealogy and settlement history are well-preserved through labels for the Upham Cem, Sharon Valley Sch, and the Hansonville Sch. Numerous family-named homesteads and operations like Willow Glen Ranch, Finley Ranch, and Robinson Mills are scattered across the flats and ridges, including Swedes Flat and New York Flat, illustrating the early migration and land-use patterns of the Sierra Nevada foothills before mid-century modernization.
