Long gone. Removed in early 1990s. From above you can just work out where it sat due to different vegetation. It was not in good condition in the final years that I can remember from a brief visit ( not staying).
As mentioned in the CalMerc piece, I still miss it, due to having fond memories of starting and finishing a both-sides-the-Lairig day there in June 1988 (when the weather was fine almost the whole way round until the heavens opened as I crossed Lurcher's at the end and I was very glad to be able to use the Sinclair as a bolt-hole).
Thanks all. Yes, it was probably a bit to convenient for a short walk in. Not sure if we will have enough time to get into Corrour......I guess that is the idea!
