The advantage of crossing high is that the skier will then be above most of the sliding mass of snow if an avalanche does occur, and he is therefore less likely to be dragged down by the avalanche or buried in it if he should be carried down. It is usually much safer to travel along ridges than in gullies, a flat-topped ridge being ideal. The skier should, of course, be sure that what looks like a flat ridge top is not an overhanging cornice. The skier should be careful to observe and consider not only the snow on which he is skiing, but also the snow above and below him, since an avalanche falling from below may undermine the snow on which he is skiing, and an avalanche starting above him may sweep across his path. The bottom of a narrow valley is dangerous if either slope is in danger of avalanche. |
