Photograph showing Alice Kimball panning a sample of gold discovered on her ranch near San Diego, California. Mrs Kimball turned down offers of $20,000-$30,000 for the rights to her land. The discovery of gold in California in 1848 led to mas immigration into the state, with over half a million people from all over the world pouring into California in search of riches. Gold was first discovered in the San Diego area in 1870.
