I'm having three days, possibly next month, at lands-end. I'll be mostly circle spotting, but plan to take in some Dolmens too, so I'll be by this 'hut' thingy. Let me know what to look for!
I will try to get a scan of the photo by then...dont know if it will help much though! Lots of settlements marked in the area.
Enjoy your visit.
