1950 Map of Grass Valley

About this map

Gold mining operations dominate the landscape around Grass Valley at the mid-century, reflecting decades of hard-rock extraction in the northern Mother Lode. Massive workings such as the Empire Mine, the North Star Mine, and the Idaho-Maryland Mine flank the town center, while features like the Tailings Ponds and the North Star Central Shaft indicate the industrial scale of these operations. The settlement pattern follows the gold, with small communities like Boston Ravine, Hills Flat, and Glenbrook clustered near the claims.
