We know the orientation of the horse ,and it is not to the west , as it "appears" to the author . But every pic tells a story and that one shows the road below horse just at it turns sharply to the west , enough to show the change in angle (about 70 degrees ) between the orientation of the horse and the road .It also shows that the top of the ridge or at least what can be seen from Dragon Hill is relatively flat and there is no "high rise in the immediate topography ", following the rise of the sun in it's putative "roll" .
