I was re-reading the "Beaver Pond" post at TwoHeadwaters and was reminded that I wanted to post one more thing from Paul Hill. In the Beaver Pond post we see a roofless structure, discussed as a possible collapsed chamber (here is one photo of this interesting structure). I do not see evidence of collapsed roof material in the middle of the opening, so perhaps the structure was roofed with organic material and nothing remains?
Anyway I found two things like the following at Paul Hill:These looked a bit like sand and gravel "borrow pits"; so I suppressed the first one, thinking it did not fit well with my narrative. When I saw a second example, however, I took a picture and wondered if perhaps this might be a legitimate part of the "site".
The Beaver Pond "chamber" is somewhat similar. Then I remembered another example from the top of Horse Hill (reported here):
So this is four examples (one from Beaver Pond, 2 from Paul Hill, and one from Horse Hill) of similar structures found at rock pile sites. Is it possible these are part of a particular cultural pattern that includes rock piles?
