Gold Panning and metal detecting the Slab on the Llano River

I spent part of the day at the Slab on the Llano River. First, I tried Creviceing and panning but must of the holes have been cleaned out. I will have to wait till there is another flood for them to be refilled. After panning for a while, I tried out metal detecting and found some coins then near the end dug up a beer can. When the can came out of the hole the glint of gold caught my eye and I found a 10kt gold snake ring thing.
