Southward are the peaks of the Black Mount and the peaceful hills that feed the upper waters of Glen Lyon; then Buchaille Etive and all those wild, rocky mountains further west, dominating wild Glencoe, stir the memory with the story of how Campbell of Glen Lyon betrayed and murdered the whole of the M'Ians with treachery as black as the cliffs of the Aonach Dubh and as cruel as the winter winds that sweep mercilessly across the corries and pinnacles of Bidean nam Bian, the peak of the storms. Or in imagination I follow Alan Breck with Davie Balfour as they flee by the sea-loch that separates Appin from Mamore up and across to the great moor, toiling and resting, but ever onward, till amongst the labyrinth of glens in the heart of the forest of Ben Alder they found Cluny Macpherson. Yes, Rannoch moor is wild and desolate; and could the grey blocks of stone or the bare slabs of granite that lie amongst the brown heather speak, surely there would be many more tales of bygone adventures to listen to and wonder over. From Rannoch my mind wanders across the stretches of blue water, past stormy Ardnamurchan to the island of Mull. I am on the summit of Ben More; below lies a ridge smothered in snow and ice. I am trying all I can with words of sweet persuasion to entice my companion, Colin Phillip, down what is obviously the shortest route to the next peak, A Chioch. But he says it is impossible, he will not trust himself on that slope of snow and ice. Now my thoughts fly to the shores of Loch Earn. I am listening to one, a geologist, who expounds to me the marvels of the prehistoric glacier; he also, with words of sweet persuasion, is trying to make me believe that Loch Morar was excavated by a glacier. Those wonderful geological truths, how simple, how all-sufficient they are to explain to the uninitiated the why and wherefore of the ancient mountains; but put not your trust in them; they suffer by the process of evolution, and are changed. Without doubt, in those days Phillip believed that I was totally ignorant of mountaineering; whilst now, perhaps, that geologist thinks that I am equally ignorant of the truth. Whether it is the truth about Loch Morar that I mean, or about that geologist's statement, or about my own, I really don't know.
