The third and final Datum stone in the Llia valley set up. This is the view looking precisely true West towards Maen Llia and Datum stone 1.
The stone here is in its original overgrown state before I pulled back the turf to see what was underneath.
I believe this may be a natural stone in its natural state, untouched in any way, with no discernible signs of packing or tooling, but used as possibly the original Datum stone that the other stones are aligned with. It’s position would seem to be too coincidental to be an accident.
