Somewhere in northern Rhode Island is a large patch of preservation land with some small ponds and wetland. On a warm Saturday afternoon in January, I was walking there and I noticed these two manitous to the west of the trail.
I have seen single stone rows incorporating remarkable boulders at other sites in RI. They are often at the edges of slopes and meadow areas that could have been cultivated by the Indians. The walls could have been boundary markers, and incorporated the symbols of the clan using the fields. Snakes could also have been fertility symbols.
