LAND HISTORY AND NEWS — LAYER B

Tuolumne County's Sonora Mining District was the Mother Lode's heart during the 1850s–1870s, producing deep quartz lodes along the Sierra Nevada foothills. Historic mines like the Jackpot and Argonaut were hard-rock operations yielding hundreds of thousands of ounces. Today, the same fault corridors host active exploration — the Mokelumne and Stanislaus River drainages remain productive for small-scale placer under the state suction dredge moratorium. The BLM Folsom Field Office handles federal mineral claims; many historic mine adits are still visible on public land.
