As is the case, "most" of the easy gems and gold were taken by early prospectors, but there is still plenty of it that was left behind. Getting to it and getting it out is the tough part, but doable.
I did take 3 bottles of water and a red bull, but the heat, my coat and the weight of the garnets and sapphires threw a wrench into my plans. When I go back up tomorrow I'll be leaving the jacket behind as well as any unneeded weight in my backpack and I'll pack some additional waters. It will be easier this time since I know exactly where to go though. Thanks!
