On top of a mound
I had noticed the mound earlier, but did not then have time to examine it; see NS4868 : A mound in the woods, which discusses the nature of this and other raised areas nearby.
On this occasion, I took a quick look at the top. What was exposed of the material of the mound seemed simply to be earth, though with, in places, some wood mixed in.
