This is from the Woonsockett "Call" [Click here] Thanks to Heidi and Keith for the link.
I have spoken with a few other experts in the subject of rock piles, people who have read most of what has been written on the subject and who have spent years in the field studying rock piles. The consensus is that there is no reason to think the piles in North Smithfield are burial mounds. On a personal note, I think it is irresponsible for non-Natives to be talking about burials. Most rock pile sites are not related to burials and painting with such a broad a brush threatens rock piles in general.
