Exotic discusion about Gems!

Ok. i want to go hunting and digging for Quartz or Amethyst. i live in the NW part of georgia and recently had a flood and it rose my creek and then went back down and now there is a big opening of a wall of clay. i wonder if i can digg in that wall of dirt and maybe get some Quartz. cuz i hear theirs lots of good quartz in georgia and South carolina. i would be amazed to find a good piece of quartz thats not just a big granite or marble boulder. there are way too many worthless boulders in my creek and around it. hope this helps.       . i wish on starting a collection of crystals and gems from the wild that i find myself.
