Morgan Mine & Carson Hill Nugget Site
Discovered in 1850, it became one of the most famous lode gold mines in California. In November 1854, miners unearthed the legendary 'Calaveras Giant' (Carson Hill Nugget), which weighed 195 pounds (2,340 troy ounces) and remains the largest gold nugget ever found in California.
Field Research Notes
Carson Hill is marked by a historical monument along Highway 49. Much of the hill is covered by a large modern open pit mine and private property. Do not cross fences or trespass on active claims. Metal detecting is permitted on surrounding open BLM land, but ensure you cross-reference active claim maps.
