Done a bit more digging on this site and found the following:
There were two "cup and ring stones" found nearby but noth were removed and are now in Alnwick Castle museum (Keys to the past links below).

Can't tie them directly but these may be two stones in the Rock Art site listed as Beanley Portable a and Beanley Portable b, noth look very impressive, see:

Also if you look at the latest map on there and on google/virtual earth there is a clear circular ditch settlement just to the North of the rock outcrop (55°27'28.99"N 1°51'24.80"W). The entrance to this is shown on the map and seems clear from the sat images (I LOVE Goggle/Virtual earth!) as facing towards any trackway that would have come out from the site, passing through an "entrance" at the rock outcrop.
Missed this one in my visit so a couple of things to look at when I get the chance to go back. The more you dig on this stuff the more interesting it gets.......
