1. Hydraulic Mining Marker
Inscription. Hydraulic gold mining was introduced in the 1850ís. Men with hoses blasted hillsides with powerful jets of water, which reduced the hills to mounds of gravel 20 times faster than with pick and shovel. Massive quantities of gravel and silt from hydraulic mining washed into the river channel, filling the streambed and contributing to flooding in the valley.

The U.S. Bureau of Mines, estimated that $81 million in gold was removed from California mines in 1852. Between 1848 and 1855, approximately $400 million worth was chipped or blasted out of the mountains. Today, that gold would be worth approximately $8.5 billion.

1. Hydraulic Mining
Hydraulic Mining was the quickest method of mining gold in placer deposits. Water would be carried to the mining site via canals and ditches. From there the water would flow into a hose.
The opening of the hose was larger and higher than the other end. Attached to the end was a pipe. The weight of the water going

into the hose would force it out the other end at great pressure. As the jet of water cut into the hillside, it would wash the dirt and gravel down into a sluice box. This type of extraction, had vast environmental impacts.
