Thanks, rock. There is no doubt the Quartzite that comes from the creek has a tumbled, or worn down look the longer its in the creek. In the pic below the two Savannah River pieces where made in the same time period, IMHO, with very similar material. The piece on the the right was found in the creek bottom, the piece on the left was found on high and dry ground over looking the creek, our four-wheeler track.
pretty cool viking
i don't know what creek hunting is really about but it sure sounds cool!
