What is Placer Gold Mining? Yukon Charley Rivers

The word placer is thought to have come from Catalan and Spanish, meaning a shoal or sand bar. The word entered the American vocabulary during the 1848 California Gold Rush, and when gold was discovered in Alaska and the Canadian Klondike in the late 1890s, the gold-seekers who rushed northward brought with them various placer mining technologies.
