Gold Bug Mine, an old gold mine dating back to the mid 1800s when the first gold rush in North America began. Here, a guide posing as a miner demonstrates how the men loaded the explosives. Miners drilled a hole, then pushed dynamite sticks into the hole with a wood stick. The exploding dynamite blasted out the rock so ore could be reached. Using this method with explosives and drilling the holes by hand, it took two to three days to progress about two feet. When one man did it, it was called 'single jacking.' When two men did it, it was called 'double jacking.' Placerville, California, USA
