Roman legions marched from Raedykes to Normandykes Roman Camp, somewhat east of Cairn Mon Earn as they sought higher ground evading the bogs of Red Moss and other low-lying mosses including the Burn of Muchalls. That march used the Elsick Mounth, an ancient trackway crossing the Mounth of the Grampian Mountains,[4] lying westerly of Netherley.
