This is the personal site of David J. Radcliffe who has spent some time photographing and recording a range of sites, including neolithic, bronze age and disputed antiquity.
I highly recommend taking a look at his list of sites before visiting as he lists a lot of places not currently on TMA.
Visited on 03-08-08 and the sprials were clearly visible. We parked up on the opposte side of the road and headed over to the Stone. The spirals were near instantly visible – although I was working from previous notes suggested the spirals were located towards the bottom of the Stone. Still, heartening to find the spirals still visible following debate in earlier notes as to whether they had been eroded entirely.
The Spiral Stone 03-08-08: The spirals were still visible – the centre sprial being most prominent in this image. As noted, an overcast day may give better photograpic results.
