Hi G
As I think I've mentioned before I get a bit lost on astro stuff, azimuths and such like. I much prefer the looser idea of rough orientations. Although I have to admit that some sites do have a precise encoding I believe many have a general idea, linked to a cosmology of cardinal points.

I have a problem with the interpretation of the monuments of eastern Cumbria which hinges around the cultural preception of the area. Because it's Cumbria and Cumbria generally means the fells there's a sort of assumption by some that the landscape orientation of many of the monuments are associated with the central fells.
When I visit the area the overall impression I get is the Pennines and the rivers, Eden, Eamont, Lowther and Lyvennet, the fertile valley, the mystical river, with it's blood red stone sandstones, the bones of the earth white limestone, the full-on madness of the Helm wind that blows out of nowhere with a force that can uproot trees or take the roof from a house, a wind that blows down from a hill that was deemed so wicked that they had to send a saint up there to exorcise it. The self same hill that dominates Long Meg, Little Meg, Glassonby and is framed in the entrance when looking out from Mayburgh Henge.
