(3) Effort.—Much less energy is expended on a spring than on a winter ski tour. In winter most of the climbing is done on ski. Tracks have to be made in the soft snow; a gradual zigzag course has to be taken; time is wasted over ‘kick turns.’
In spring one climbs on foot or on crampons. The ski are dragged behind on string. On level or gentle slopes the weight of the ski is almost imperceptible if they are pulled along on string. On steep slopes they are by no means a great hindrance. It is surprising what can be accomplished by a man who is dragging instead of carrying ski. I have seen Knubel climb a short but very steep snow and ice wall in which he had to cut half a dozen handholds, and on which he had to steady himself with one hand while he cut hand and foot holes with the axe held in his right hand. Meanwhile his ski were dangling on string—attached to his waist—over the bergschrund below.
The ski should, of course, always be secured by two strings in case one breaks.
In spring on hard snow one climbs very nearly as fast dragging one’s ski as one would climb without ski, and from 50-100 per cent faster than one would climb if one was forced to ascend the same slope on ski with soft winter snow.
The saving of effort is as remarkable as the saving of time, for it is much easier to climb direct on foot than to zigzag up soft snow on ski.
Apart from the upper snows, the approaches to the High Alps are easier in spring than in winter. The snow at night is nearly always hard in May. The narrow valleys, filled with soft powder snow, are covered with a firm groundwork of hard crust in spring. The climb to the club hut is usually done at night or in the early morning. Though the snow lies down to five thousand feet well on into the middle or end of May, so that the ski descent can be prolonged down to very low levels, it is usually possible to pick a route up snow-free slopes (either on southern or south-westerly or south-easterly slopes) far higher than the lowest levels of the snowline. Paths can be utilized instead of snow slopes, more especially if the peasants have begun to tramp out the paths for their own purposes. The long detours, often necessary in winter, to avoid dangerous avalanche slopes are needless in spring, for such slopes can always be crossed with safety at night when the snow is crusted.
(4) Scenery.—I have tried to show that the High Alps yield better and safer ski-ing in May than in winter. Even if this were not so, May would possess a charm for the mountaineer that no other month affords. It is perhaps idle to compare the rival beauties of the four great alpine seasons, for, even if one season could be proved paramount, the true mountaineer would wish to study the mountains in all their moods. The icy virginity of the High Alps in winter reveals secrets that are hidden in spring and in summer.
None the less, if it be permitted to state a preference, I for one should give my vote to May months. Contrast is the greater teacher, and May is the month of contrasts. I think of moments when one stepped on to a high ridge after hours among the burning snow-fields of May, and looked down, with a shock of surprise, on to the valleys dressed in a green that was different, transfigured, miraculous—a green that the valley-dweller has never seen. I think of quiet evenings after long days among the snows, when one strolled down through the scented pines with one’s ski on one’s back and the music of a perfect run still echoing in one’s heart—of the Dollfuss in May, a little oasis of green young turf covered with gentian and anemone in a wilderness of burning snow and granite ridges. I think of a sunset hour just above Rosenlaui, following four perfect days among the May glaciers, the foreground of marsh-marigolds a sheet of flame, and the whole valley one full-throated chorus of spring. Running water is always beautiful, but there is no music in all the harmonies of Nature to compare with mountain torrents in spring after days among the dead silence of the upper snows. Such are the contrasts that reward the mountaineer in May. Within the compass of dawn and sunset he can live through the cycle of the seasons, can pass from winter to spring, can enjoy the best that snow yields to the ski-runner, and the chiefest rewards that the hills yield to those that explore them when the great rebirth of colour and music has finally prevailed over the stubborn obstinacy of the retreating snows.
In order to understand the conditions that prevail in the High Alps in spring, the effect of sun on snow and the various habits of sun-formed and sun-melted crust must be grasped. These are dealt with on pp. [412-417]. Avalanches are analysed on pp. [423-438]. All that now remains is to consider the application of the principles laid down to the various months of spring.
