Enrichment of Gold Veins
November 2000 by Edgar B. Heylmun, PhD
Most of the world's great gold mines are in secondary (supergene) enrichments in veins and stockwork, brought about by physical and chemical processes.
An Unusual Death in Downieville's Gold Rush
While women were extremely rare in the early California gold camps, their relative absence did not always guarantee their safety or protection if they happened to be of Mexican nationality. The most memorable, graphic example of this tendency took place in Downieville, seat of Sierra County located on a fork of the Yuba River.

The North Star Mine
Back in the early 1800s, there was a gold mine being dug in a mining community called Garden Valley. Garden Valley is located northeast of Sacramento, between Georgetown and Coloma. They called it Garden Valley because there were some miners who thought there might be more money in growing and selling vegetables than in mining for gold.
