Carn nan Ghabhar of Beinn a' Ghlo, above Blair Atholl. Nasty stony summit, and just starting to rain is the just when to get into the bivvy: it's much nastier when things are already wet. Slight landslip gives this bivvy site just down from the crest, and nicely grassy. It's more sloping than it looks in the picture. If I wriggled around in the night enough to get onto that snow patch, it'd be a rapid descent to the valley.
