Mining methods of the Klondike Gold Rush
Underground mining. Most of the gold was below the surface. The miners first had to thaw the permafrost before they could dig. A fire burning all night was used to soften the ground. This would then thaw to a depth of about 14 inches and the gravel could be removed. The process was repeated until the gold was reached. No support of the shaft was necessary because of the permafrost. However
