Cairngorm Club overnight meet. I left the corner of the forest near the east end of Loch Ossian at 04:30 alone and went along the S side of Loch Ossian and up the south ridge of Stob Coire Easain (top part in mist) to arrive at the summit. I joined two other members. Went over summit of Stob a’ Choire Mheadhoin and down to Tulloch Station.
