This is some kind of serious glacial anomaly I came across after getting my socks soaked in Chesterfield Gorge. The picture doesn’t really convey the size—-the rock is maybe 9 feet across and at least 3 feet tall (not including the part of it that’s submerged in mud). It doesn’t match any of the rock of the surrounding gorge, as you will note from the next picture. It’s sculpted so smooth by the water it almost looks like carved marble. I wonder how it got here.
The usual local rock, sedimentary shale.
Horse Mountain, Haydenville, MA. The white fuzzy stick-animals are alpacas.
