East Kennett Long Barrow 5

Thanks for the confirmation.

The shotgun shells were a little disconcerting, but then we found half a clay pigeon aswell, so we relaxed.

Anyone know if we made it to Adams grave? I'm thinking not, as it was fairly close to the longbarrow, although it was high up...

Is very high up with brilliant views of the pewsey vale.
It has a few stones at the front but it sounds like you discovered one of the many destroyed round barrows.
