Hydraulic mining used a water cannon (called a monitor) to wash the hillside down and into a huge sluice box which separated the Gold from the dirt and gravel.
Hydraulic mining blasts away the surface of the mine with highly pressurized jets of water. This allows for easy access to the minerals underneath. A negative consequence of Hydraulic mining is the damage to the surrounding environment.
