The Elevation level of Dun elm is the same altitude as the 3 Carrowkeel Cairns in Ireland

I was making comparison of terrain & landscape between Wicklow Hills & Pennines as was curious if there were cairns on West Nab at Meltham. But to my finding are that actually as a Site itself the natural Long barrow form of Dun Elm is the same altitude as the Carrowkeel Cairns, in fact the allotment along the side is the exact same altitude!
