Gold is often found alongside quartz - as water erodes the quartz, the gold is carried away by the water.

Have always thought it would be neat, even if not profitable, to buy a pan and see if a few bits of gold dust can be found.
My dad and brother would go underground and do the actual digging; my mom and I stayed topside, with me running the hoist and the both of us working the sluice box.
I found a nugget as big as my thumb that year. We found a number of smaller nuggets as well.
Two years before, my dad had a placer claim for a stretch of creek about 10 miles from the mine just described, and we spent all summer out in the woods, dredging and panning for gold. Didn't find anything, though.
California works too, especially for small miners, because for larger operations environmental concerns can be a pain. But the Sierra Nevada is very well endowed.
