We just did this over Memorial Day weekend and it was a blast. My 7 year old daughter starting coming home with "cool" rocks in her pocket last year and we just encouraged the interest, went to a local geology show, and got hooked. Now I'm in the back yard cleaning 50 lbs of quartz, clay, and rock in various sizes. I don't know how ethically we mined (dug in dirt), however, since I heavily relied on my daughters as underage and super-distracted workers. Oh and I had to raise my voice at my wife (not normally super-nerdy) to tell her to stop, that we had to take the truck back . But she was hooked, and the story has entered family lore.
