Gold Rush: 1848-1860: Mining Techniques | Picture This

The California Gold Rush was a multicultural place and without the knowledge of people who knew how to mine, it may have ended much earlier. The mining techniques used in the Gold Rush evolved over time. This evolution tells a much more complex story than it seems at first glance; the change in mining techniques reveals the myth of the Gold Rush.

GOLD PLACER DEPOSITS - Earth Sci

Gold will collect at the head or foot of a stream bar or on curves of streams where the current is slowed or where the stream gradient is reduced. Pockets behind boulders or other obstructions and even moss-covered sections of banks can be places of deposition. Best results usually come from materials taken just above bedrock.
