>>2780849btw in that photo you can kinda see the little ditch we dug surrounding the stone circle, to divert water. this is from inside, facing the other way, you can see it is dug into the hillside a little bit.
most of the day was spent moving a VERY large rock in the middle of the enclosure, easily 200kgs. we did it by leverage and using rocks to shore it up, slowly raising it up to a position where it could be slid out.
