Hi Flat Sky

Nice to hear from you, where abouts are you?

My latest "puzzle" is at Letter Moor...

This is on open moorland just south west of Coliford dam. The best way to get there is to either drive to the car park beside the dam and walk to the bottom of the hill where a tarmac lane goes off on the right. This soon crosses a bridge and then turns into a muddy track. Letter Moor is the area on the right as you climb. I would advise taking an OS map as the feature is marked...but still not easy to spot on the ground. As you will see by my field notes I have had a response from CAU which is of little help!

If you get a chance get up there and see what you think, also take a look at the eastern horizon from the circle. Is it me or are all the natural high points equal distance apart?
