As the water has been low, I check out sites as schedule permits. This is a great way of staying aware of erosion and particulars on each of the 4 closest and most productive sites within a few miles of my work radius. These are from a bagfull of diddies found in an hour walk from a site we refer to as "camino."    This is on the other side of the road  which bisected this site . (approx 200x100) is the gv53 most of my stuff came out of., and which had the recent archaeological  survey in which I participated.  All of these came from a 2 foot area washing out of the side.   Yesterday I stopped at the Baytown bridge site where I found the shell point.and walked a bit.   Got a plethera of pottery and a thumb scraper.  That place is bigger than gv53, probably older, and is subject to greater erosion problems. 
 

Garry's amazing oyster shell which grew around the dart point! I had to include this  much better picture of this artifact than one we included in an earlier update.
