We continue to seek out a patented mining property with an owner who is willing to host such an event with a water supply and enough remaining gold to make it worthwhile for the students.

The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.

I frequently get asked, "What should I look for when I am out prospecting that will tell me there are good amounts of gold present in the ground?"
