Hmm, yes I suppose in comparisson to the two hills on either side it looks pretty moderate but if they weren't there it would seem quite high above the top of the recumbent. On the other hand if I remember correctly, I'm sure you have to step up a little slope to enter the circle so a person of average height standing a few feet in front of the portals may find the recumbent is near in line with the horizon or not massively lower? Hence why I'm looking for pics :)
