Pits and split wedged rocks from Taunton

I went back to Taunton, to the east end of Rocky Woods Rd (actually Westville), and had a less than spectacular walk. There were a lot of split-wedged rocks and I kept noticing pits in the ground which, had they been lined with rock, might have been called "mounds" (sounds contradictory).

 Pits are not easy to photo, but shadows help show what is there:

A fanciful thought: near a burial you sure don't want spirits from the nearby rocks out and about.
