Tip of the Month
Last month I wrote about rime ice, and how useful it can be in determining what the local wind direction has been recently. This knowledge plays a crucial part in our avalanche decision-making process by indicating where the dangerous lee slopes may be.
For the same reason, it’s also useful to know about, and recognise, sastrugi. These are slightly reminiscent of sand dunes in the snow. Like rime ice, the direction of the wind that they indicate is slightly counter-intuitive. Sastrugi are carved out and eroded by the wind, which gradually wears away at the windward side and deposits the snow crystals on the sheltered side of the increasingly growing feature. The steep, scarp side is the side that has been carved and thus indicates the direction of that the wind has come from.
Sastrugi can be just a centimetre or so high, but in time can also become several feet high and can be physically difficult to move across.
Fact of the Month
Tower Ridge on Ben Nevis has a curious history. The first time it was climbed as complete route, was actually in descent. J., E. and B. Hopkins descended the entire route on 3 September 1892, having ascended it as far as the Great Tower the previous day. The first ascent (and also first winter ascent) was by Norman Collie, Godfrey Solly and J.Collier on 29 March 1894.
Route of the Month
If you are looking for an exciting winter/walk scramble (or summer, come to that), on which ropes are probably not required (depending on conditions and your ability), then try this suggestion in the Mamores. From Achriabhach in Glen Nevis, ascend the north ridge of Stob Ban (scrambly at the top), then carefully avoiding the cliffs, descend the steep east flank and ridge. Follow the skyline around towards Sgurr a’Mhaim via the Devil’s Ridge (usually undertaken as part of the Ring of Steall walk). The views of Ben Nevis from here are unusual and very impressive.
