Here is another curious boulder, this one is from the Roslindale/West Roxbury area [I think] near Turtle Pond Parkway. In the next picture, note the ring of stones in the foreground. This is a particular style of prayer seat, found in this type of context: a ring of stones to the side of a prominent boulder. My opinion is that this was done in order to share some of the energy and personality of the large rock.There were two rock piles Bruce found near this same boulder. It looks like the boulder was the focus of additional ceremonies.
