LAND HISTORY AND NEWS — LAYER B

Nevada County produced more gold than any other California county during the 1850s rush, with the Grass Valley Mining District ranking among the wealthiest hard-rock gold producers in North American history. The Empire Mine alone operated until 1956. Today, active prospecting continues in the South Yuba and Bear River corridors under the suction dredge moratorium — dry sluicing and highbanking with non-motorized pumps remain legal on most federal waterways. The BLM Mother Lode Field Office in Folsom handles claim recording and surface management questions for this district.
