Notes:
Collected by Kevin Weir a BLM employee and Bureau of Mines employee from 1972 — 2007.
Hyraulic mining was first done in CA in 1853. No digging was necessary. It is a form of mining that employs water under pressure to dislodge rock material or move sediment. Large hoses were used to spray high pressure water onto a rock face, the water dislodges the rock bearing gold. The water and gravel were captured in long toms and washed in the usual fashion.
