"With Jonathan Bellarby. From Achlean. We ascended beside Allt Garbhlach to reach Mullach Clach a’ Bhlair, Diollaid Coire Eindart, Tom Dubh (small cairn – also 2 very small cairns at other points which look much the same in height), and Carn Bàn Mór. Snow on the ground high up, with some ice." — peter43 • Apr 21, 1985
