The base Bothy map I've seen several years ago, wasn't valid then, nor now. Best to stick with the MBA handbook or check on their website if not a member.
Vast number of 'lost' bothies from the 1990s and before included. Some still standing and locked, others burnt down or roofs collapsing and some repurposed.
Hate to add to the list in view of how much effort will have gone into this, but Luibeg is a locked cottage. The bothy that sat beside it was burn down about 30 years ago and replaced with Bob Scott's Bothy (which you also have marked, fairly close to its actual location). But Luibeg is not open and I'm sure the estate won't like seeing it on there.
Nice work. This is of minor importance but I believe Camasunary has been taken back into usage by the estate, but who have in their generosity provided a new building on the far east side of the bay near where the path drops in from the Elgol road iirc away from the location of the original building on the west side of the bay near the river.
