Prospecting for gold in the western United States helped to bring settlers into the region. In the 1800's easterners and Europeans heard of the unbelievable wealth west of the Mississippi. Dreams of instant wealth drove hundreds of thousands of people to the promised land to prospect for minerals.

Gold is a heavy, malleable, yellow metal. Since gold is mainly found in granitic rock, the weathering of granite plays an important part of mining "placer" deposits Miners used these properties to "pan" for gold. This technique allows the denser gold flakes to settle to the bottom of a pan. This technique is still used today.
