Another large berm, perhaps a serpent - from the Journals

Between Redemption Rock and Lake Watchusett in Princeton MA, there is an artificial berm overlooking the lake from the east. A stone wall leads down to where the slope begins to drop off to the lake. Where the wall endsyou can see some kind of rock pile structure behind it. Upon closer examination it is exposed cobbles from an artificial landform.
So we go up on top of the landform and try to get some idea of it.
It leads off into the distance where it joins a natural peninsula going out into the lake.
