Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.

Gold prospecting and identifying goldbearing areas have become increasingly more feasible, due to research developments on the geological process of gold formation. (See References 1.) Gold bearing areas, mostly throughout the western United States, have drawn and sprouted entire communities based on prospecting. (See Reference 1.) Various hypotheses exist on how gold is formed as it surfaces ...
