Bolt sits at centre of summit cairn at the island's high point. It's a bit of an oddity: superficially appearing to have had the head broken off leaving the shaft embeded in the rock, but then there's the flange/washer that doesn't quite make sense.

Remains of a bolt: flange flush with concrete, stem broken off just above. In cairn, easy to spot. My third time here. Part of a day charter with Seaharris, easy landing in flat calm conditions

ferrule in concrete in cairn, which seems a lot less tidy than when we were here in 2012; weather a lot colder too but fine views. landed S side on weedy rocks, as before

Nearly missed this one - buried in the cairn. Now visible if you peer into the cairn. Not pre-planned, luckily had a 1:25k map extract with me which showed it. A group of us chartered the seaharris RIB for 2 days island bagging.
