Thanks to Pete G posting his link to Google maps, I've become somewhat addicted to this newly enhanced mapping service!
Sadly, Thornborough is still lower resolution, but I had a good old study of Stonehenge's surrounds (some great markings in the fields!)... But this new nearby industrial estate or whatever it is looks to be a bit near some barrows for my liking...

And does anyone know what this might be?
