Hi Jeff you found it, and I am surprised that the site is not yet completely covered again because of the impending I-95 road widening project. I was told the sites last day was two weeks ago. It is apparent it is still fenced in and active.Good news and I noticed they covered up the tunnel going under the fence into the private property with a white plastic tarp.
Here is a shot that includes the base of a small clear bottle (upper center) but could not see the top and unless it was flint glass (?) appears to be trash from a later date
