Up on Sgurr a' Choire-bheithe yesterday we saw what appears to be a brand new or significantly 'enhanced' cairn. It's on the 913m summit as marked on OS 1:25,000 mapping, about 100m NE of the large pre-existing cairn that the OS also mark.
Someone has prized up multiple big rocks for it, and added chunks of turf and moss, leaving excavation holes all around the summit area. It's a right mess on the ground. The new cairn looks dreadful too.
Why do it?
Maybe there's uncertainty as to which of the two cairns marks the true summit, so person(s) unknown thought they'd do the world a service? (I thought it looked like the high point is at the older cairn, but the OS spot height suggests it's the point now graced with a new cairn).
Perhaps adding turf was someone's attempt to boost the apparent height of this top-end Corbett over the Munro threshold?
Kids?
Mystery cairn enthusiasts?
Whatever the idea it must have taken hours, and it's still a really slapdash bit of work.
