I have to agree with Pure Joy, I couldn't work out which stones were part of the circle and which were just "stones". Not having read up on the area before the walk I was not sure if the circle was large, small, standing, recumbent........
So, did I walk through the circle or not, was it the large one just off the track or the smaller one further down the hill where there are cairns marked on the OS map but look more like a small circle of stones.
I will have to do some research next time.
It was worth the walk just to rock the stone on Louden Hill whilst a rainbow arced over Roughtor.
Whilst coming across the moor from Stannon Stone Circle back to the track that runs past the Louden Hill and Fernacre Stone Circles I got a bit lost finding Louden Hill Stone Circle. I knew that Louden Hill Stone Circle was a ruined circle but I didn't know how many stones were supposed to remain, and didn't know exactly what to look for. So when I came across 5 stones that looked like almost a quarter of quite a substantial circle, plus a few other stones, I presumed it was the Louden Hill Stone Circle. But then I realise that (a) this was not much of a circle even for a ruined circle, and (b) I was only about 300 metres from the end of the Camperdown Farm walls and was probably at about SX128793 (i.e. about 300 metres West of the real Louden Hill Stone Circle). So is this possibly another circle? Or just some stones that happen to form a part of a circle?
There are 5 stones, all recumbent. 2 large, 1 small, 1 overgrown and 1 just a tiny speck poking through. There is also another tiny speck poking through but that is a little off line. Towards what could have been the middle of a circle are two medium sized stones, plus an overgrown stone about 5 metres ENE of them. This is all about 30 metres to the South of the track.
About 50 metres to the East there are several stones scattered on the South side of the track, and a lone stone to the North of the track. I later discovered the real Louden Hill Stone Circle but this area still has me intrigued.
