Not quite sure what you are suggesting LS . In relation to the sun roll ,if it had been worked out before the build of the mound , it would have been much more difficult than finding a spot after the build . There is one good spot others get close but the sun appears or disappears to early or late or sinks into the hill .
The obviously all important siting is odd in that it could have been in a more conspicuous position if multiple viewpoints were the intention ,Waden Hill blocks a fair percentage of the view from the north east to east or alternatively the view towards that area is blocked .
