Chapter VII · ICE AND SNOW CRAFT (continued 3)

Reading edition

On any surface where a glissade is justifiable it is possible to stop with these combined brakes within a distance of a few feet, provided that, as with a motor-car, they are not jammed on so suddenly as to upset the equilibrium and detach the points of contact from the surface.

For gentle checks to pace, touching at intervals with the axe point, or pressing on one or both heels momentarily, is sufficient.

Sitting.

Practically no snow slope of right consistency and termination is too steep to glissade down; but many incline at too low an angle, or are of too soft a surface, to glissade down in a standing position.

So long as we are young and thoughtless, and place the enthusiastic memories of youthful tobogganing before the after-discomfort of wet clothing,—a youth which in the case of mountaineers appears to extend well on into the sixties,—we hail such soft slopes as the recovered opportunity of recalling a lost ideal; and we descend them sitting-wise.

For sitting, the methods of guiding and braking with the axe and the feet are much the same as for standing; only they are more clumsy and proportionately less effective, as the slope also is less exacting. The axe is held under the arm, in the same manner, to brake, and is transferred from side to side to steer.

The foot steering is performed by obstructing with one heel or the other. For a sharper turn, the legs are lifted and swung across in the desired direction. To avoid rolling over in a quick turn like this, the body leans over on the side towards which the turn is made, and the weight is thrown inward and back upon the axe. The whole length of the outside of the leg and thigh contributes to the steering action, as an equivalent for the canting of the feet in a standing turn. Leg and thigh thus supplement the ineffective guidance of the heels. The movement checks the pace usefully, for the snow will begin to hummock under the thighs and up under the jacket, whereas before it was merely percolating through the breeches.

In descending direct the legs are kept together, and the body is converted into as rigid a reproduction of a torpedo as the incidents of descent permit. To accelerate the pace the body can be thrown back and held stiff, which takes off the brake made by the curves of the back and distributes the weight, as on a sleigh or ski. This movement adds the neck to the other potential snow orifices.

On unwilling slopes, punting with the axe and a swimming motion of the legs can be resorted to, for propulsion; but the effort is not dignified. Shooting, or ‘chuting,’ head-foremost has an exuberant appearance, but does not add materially to the chances of pace.

Braking is done upon easy slopes by opening the legs, and allowing a triangle of travelling snow to pack between them. To brake sharply, the axe point is driven into the snow under the arm, the body is arched stiffly upward clear of the slope on the support of the axe, and the heels are driven down and in, close together.

For standing glissading, if the surface is good, we generally each choose a line of virgin snow. Pace will come of itself, and is not so important as uniformity of surface. But in sitting glissading the first to descend has the worst place. He has to make a clearer and harder track for the rest. If a trough of this kind is once formed, it will be most polished in its exact centre; and men are well advised to turn slightly upon one thigh and shoot down upon their longest but narrowest available body-surface.

A very pleasant method of descending, as a party, is to form a fashion of bob-sleigh, each man sitting close behind the man in front and having his legs held up by him clear of the slope. The most is thus made of the collective weight and the least of the collective body-surface necessarily in contact with the snow. The best situation is towards the rear of the human sleigh. The man at the head will collect most of the snow pack, and there will be only the usual moist permeations to be enjoyed by the tail.

The first man descending on an unknown slope after fresh snow, or on the occasional snow patch found at lower levels, should always make careful examination to see that there are not rock or stones near enough to the surface to inconvenience, if not injure, his descent.

Sitting glissading is useful not only on snow too soft or too easily inclined for standing, but also upon surfaces where a crust has formed over soft snow, through which the feet break under any attempt to glissade standing. On snow of this character both steering and stopping are even more difficult than they are in ordinary sitting glissading, since any attempt to drive in the heels suddenly may result in a head-over-heels fling. On such a surface it is best to lie as flat and stiff as possible, and avoid making any abrupt local movements.

The sitting glissade has been already mentioned as of use in crossing schrunds with awkward-angled or dubitable bridges. Each man before he shoots for the bridge should make certain that he leaves enough free rope and good sense behind him to allow him to come to rest on the far side without a disruptive or a premature jerk.

Stone Tests.

It is always wise, before glissading on a slope of uncertain consistency, to throw a few large stones on to the snow to test the surface. They should be as heavy as possible, so as to ascertain the weight at which the snow will avalanche. The practice has the further advantage, on a slope whose termination we can see, and where, therefore, a slight avalanche quality in the snow need not deter us from glissading, of clearing away all the deciduous snow from at least one line of descent. There is left a smooth, harder track whereon a human being can descend comparatively dry. At the best, the stones may start a general avalanche, and so leave a safe and clean slope where we can choose our line. Incidentally, the stone track serves to discover the presence or absence of concealed stones or of rock points uncomfortably near the surface.

The Rope.

To remain roped is impossible in ice-glissading, and is a nuisance in snow-glissading. The rope should never be necessary where there is any long and comfortable glissade in safe prospect. Pace and real foot-running are impossible on the rope. Its use enforces axe braking and slow-coach running at even distances, so that the rope shall neither tighten upon the front man and upset his balance nor entangle in loose coils about his feet. Every one in a roped party, however expert, must be axe braking, and wearying his shin muscles, if no more, in the vain effort to keep an even distance over surfaces of quickly varying quality and angle.

For the men in the middle of a rope, to be thus glissading is simple weariness of the flesh. On short glissades, during long climbs, the rope may have to be retained to save time, but on slopes of any length it is always worth while to unrope. If the rope has to be retained on such slopes for precautionary reasons, because the end of the slope is not in sight or because there are beginners taking part, the party should rope in pairs. Two experts can glissade fairly freely on a rope by descending on adjacent parallel lines with the rope loosely across between them. They have only then to see that it does not catch on excrescences which they themselves are avoiding. In the same choric fashion an expert can glissade alone with a beginner, protecting him and accommodating himself to his uneven descent. He follows beside or slightly behind, and is at liberty to quicken up, overtake, and even get secure anchorage in time, if he sees his companion beginning to descend the slope in other fashion than on his feet. In glissading with a beginner on a rope the pace should never be allowed to become greater than one is absolutely certain of being able to regulate, not only for oneself but for one’s companion, with plenty of margin for accidents. Once a man has been jerked off his balance, it is far harder for him to stop himself and his companion by the travelling axe brake, on a steep slope, than when he is stationary and upright with his heels well in. He must therefore keep the pace well within the speed limits.

The higher refinements of glissading, the zigzag and the free sailing on one or both feet, are of course out of the question for more than two on the rope; and barely feasible for them.

Some Variations.

There are a few occasions where exceptional varieties of glissading may be found of use.

Alternate Glissading.

In descending snow slopes of doubtful consistency, or slopes or couloirs whose lower end is concealed, and therefore an object of suspicion for free glissading, an alternate slide and anchor method can often be adopted. It is especially good for protecting beginners who cannot be relied upon to arrest their glissade at any given instant. The experienced man anchors firmly in the snow with the rope round his driven axe. The front man then glissades down until he is arrested by the rope or a call from the rear. The rear man follows, and glissades either down to him or past him, stopping himself in the latter case, if he is wise, before the rope runs out. If he is wise, because no inexperienced man can be relied upon to know what security of anchorage is required to resist the jerk of a man running out a double length of rope on steep snow. The first man then, in turn, glissades past, and is stopped by the expert with the rope. The process can be repeated until the bottom of the slope is reached, or the secure termination of a freer glissade is ascertained. The method is a good time-saver, especially in steep couloirs, but it must be worked with all caution. I tried it on one occasion with a mountaineer of confident self-security, and after sailing past him, and becoming certain that my rope must have run out, I turned round, to see him head-foremost after me down the slope. He had been twitched from his stance without so much as a perceptible check to my rope. Since then I always, in alternate glissading, turn face inward when I feel the rope is near its end, and stop myself,—for the first few ‘runs-out’ at least, until I know I can depend on my second. With a beginner it is best to stop, as last man, when one reaches him. With a good second it is enough to arrange with him that each shall call out sharply to the man glissading some three yards or so before the rope runs out, leaving him time to stop himself.

Face Inward.

Any man who wants to get all he can out of the opportunities to glissade must be able to travel in every reasonable attitude, and to change from one position to another at any instant without check or loss of control in the movement. The axe is the transitional support during all movements involving sudden or marked alteration of balance. As a convenient variety it is useful to be able to glissade face inward toward the snow. On slopes of doubtful termination, and in couloirs more especially, where it proves impossible to discover if there may not be some ‘cut-off’ below, or where the quality of the snow, and perhaps the presence of ice beneath it, make caution imperative, a more controlled, watchful and restful descent can be made with the face towards the slope. The axe head is then gripped under the arm with the pick caught behind the shoulder. The two hands are firm on the shaft in front, ready to shove the point into the snow. The legs are slightly apart, with the feet parallel and the toes inclined upward. The descent can be stopped in an instant by pressing on the axe shaft, and by forcing the toes outward and downward, so that the inside edges of the boots scrape downward against the surface. On rough icy surfaces, in order to allow us to look round, and also to prevent the toes catching and throwing the body outward, it is sometimes even safer to bend one leg up, so that the flat of the one sole rests against the slope at about the level of the knee of the lower straighter leg. The body then lies forward over this bent leg as on a firm spring, with the centre of gravity low and the balance secure. The head is freer to turn and prospect above or below. A foot brake of extra power and rapidity can be made by scraping the upper, raised foot downward along the slope with the whole force of the body—a sort of stopping kick. For hurrying the descent of awkward couloirs where the glissade of short stretches may have to be stopped within inches, I have usually preferred this face-inward glissade. In this position we not only can stop, but steer with great precision and power; and in a very confined space, as in a narrow couloir, we can side-step or side-jump easily. To jump obstacles or crevasses when glissading face inward, we must of course turn round first; but a good glissader should find no difficulty in twisting round, especially out of the last position described, with the one leg raised, which is in itself already a half-turn attitude.

The position has the additional advantage of allowing us to watch companions above; and, in suspicious couloirs, to keep a look out for their loosened stones or small following avalanches. Stones can be dodged once they are seen; and a fine face-inward glissader, whenever he sees the small, wavering, pursuing avalanche, looks round and ahead for some lower bay of shelter in the walls of the couloir, and, if need be quickening his pace, steers out of its way into safety at the edge.

Plunging.

In couloirs or on slopes faced with soft sticky snow, too soft or too gradual for a free glissade, it is often possible to save a long trudge of descent by using the ‘plunging’ step. A few long springing steps, driving the heels hard along the surface, will start a small surface snow slide, and upon this we can ride down, until it again packs, when the plunges are again repeated. If the snow joins in the game too heartily, and there is a risk of losing control and of being swept down in a cumulative avalanche, we use the swinging cross-step to the edge of the wave, and jump clear. When the avalanche has passed there may be a fine surface left for normal glissading.

On every slope where we begin to feel that the travelling mass of accompanying snow is getting beyond control, the glissader must be ready to swing-step or to jump clear of it on one side or the other. When it is past, he has also to look out for the not infrequent chance of the furtive slides which will pursue the first. If two men are glissading on a rope, the upper will be in the best position to decide when the mass is growing too big, and he must give timely warning to his companion before he jumps clear himself.

On Claws.

In couloirs of a certain type, where there is a thin covering of fresh snow over ice, or where snow has partially melted into ice glaze over rock, I have occasionally found light claws a great help to safe glissading. The angle may be too steep, and the snow upon ice too bad to allow of a prospect of descent without prolonged, deep step-cutting or slow ambling on our prehensile claws. A pair of light claws that one has no fear of blunting may then be found of great service to save time and labour. Glissading lightly and slowly on the feet, side-crouching as upon ice, or still better face inward, the claws slip down with the surface snow. Where the snow is thin, they scrape through on to the ice and retard the pace; where it thickens, they can still be forced through by throwing more of the weight off the axe on to the feet; and the descent, with the fitful brake of the axe, remains perfectly controlled.

As before noted, claws of the long-pointed pattern can be used in the same fashion on rotten ice.

On hard, smooth ice at high angles, claws of the light type are often safer than nailed boots. A good position for such claw-glissading is one of those familiar in ski-ing. We sit astride of the axe shaft with the point against the ice. We can then throw the weight back upon the shaft, and brake, while we release the feet to steer, or we can let the weight forward on to the feet and increase the pace. Either or both feet can be relieved of the share of weight if anything threatens to catch them and upset the balance.

This axe-riding position is occasionally convenient in icy couloirs, or on fresh snow, where only an absolutely slow and controlled glissade would be safe.

It can also be made use of on very rough surfaces, on dry glaciers or practice ice slopes, without the extra security of claws and trusting to the boot-nails alone. But on nails alone the glissade is proportionately less regulated, and we are more dependent upon the axe for control and braking.

On Other Grounds

Many surfaces other than ice or snow give us good practice and pleasurable moments. Volcanic ash is said to provide the finest conceivable flying footing. Sand of sea-cliffs or quarries, and even the mud shoots of the east-coast cliffs, give excellent fun; but the most common, and perhaps the most admirable sub-alpine surface is a light, steep scree slope.

On Scree.

Our method of descending these shoots is dictated by the size of the stones composing them. When they are of shale, or light enough to slide away under our weight, we need only straighten the leg, stiffen the ankle, incline the body slightly forward from the hips, and start with a long leaping stride, forcing the heels well down and in. Small scree, at a good angle, will carry us on and down of itself. The axe is held in the same way as on snow, and is only used for balance touches.

On scree at a lower angle we shall have to continue the plunging strides, leaping from heel to heel and travelling as far as possible on the stones set moving by each foot. The stronger the leg the longer may be the stride. The massing of the stones under the foot will stop each step with the softness of a slow spring, and if we are thrown out of balance by one too abrupt foot check, we can generally recover it on the next stride.

Towards the end of the slope the scree grows larger, and whether sliding or plunging, we have to look out for knee and ankle twisting. We go cautiously, but driving always harder with the heel, until the stones refuse to yield to the thrust; and then we call in our loose legs under control, and proceed to stumble or dance down the rest according to the perfection of our ankles and balance. A man light of foot and supple of joint can let his feet drift, as it were, over even large rolling stones, letting them adjust themselves to the varying resistances without checking his pace. A man who judges his scree not by its size but by its angle, its shape and the way it sits on the surface, can continue his glissade often well beyond the point where the less expert begin to fall or crawl.

Once the blocks grow too big to be kicked into harmless motion, and the drifting feet begin to slip over them into the interstices, the wise man begins to look for other shoots to carry him farther. By using the swinging cross-step described already, we can make diagonal descents of slopes on a succession of connected parallel glissades. By choosing a line well ahead, and crossing from shoot to shoot, many hillside descents of weary prospect can be charmed into a few moments of stimulating racing. It is well to remember that up-running spits of light scree often conceal themselves in depressions between ribs of rock or in hollows between slopes of heavier scree, especially near the bottom of the slopes.

The light screes that lie in these lower furrows on hillsides are among the deepest and pleasantest. Our zagging from furrow to furrow will divert our thoughts if not our feet from the last tiresome steep grass drop. Where the lower spits of light shilla thin out, generally at their lower ends, it is wise to look out for the catch to the ankle of rocks or wet earth or grass, stripped of their scree varnish by the driving heel.

It is best for each member of a party to choose a different line, otherwise the larger stones dislodged, often accumulating a torrent, may surprise a speedier forerunner. Similarly, it is safer to leap sideways occasionally ourselves, and wait while our own attendant torrent passes.

The angle of inclination at which small scree lies is invariably the angle of disinclination for big scree. Big scree, when we cannot avoid it, is an unqualified worry, and we worry out of it as we can. The method, traditionally recommended, of sitting or standing on one large stone and tobogganing down on it over the others, would seem to be only successful for distances not yet ascertained.

In Winter Gullies.

Except in the North, where winter snow gives much the same conditions for glissading as the summer Alps, winter glissading in Britain is usually upon snow-covered scree or mixed snow and scree. The end of our glissades in this case has a special risk: where the snow thins and weakens among the larger blocks, which it yet continues to cover—to our downfall. To glissade near emerging rocks is risky, on account of the probable holes and hidden pockets in the snow round them.

In gullies alone we find snow over rock. Here there is another special risk in the rock steps or pitches, which may be only partially covered with snow. The drop is often invisible from above, and an inexperienced glissader may be unable to stop himself in time, when he is close enough to recognize a break in the continuity of the snow slope. Sometimes there is a frail lid of snow more deceptive than an open break; and I have seen a man shoot over a pitch of this sort through the snow lid and down the wet rock channel under the lower snow. Where the rock of such pitches is visible, we have still to look out for another trap. We may count upon stopping as we reach the rock; but the very end of the slope, where the melting snow has run down and refrozen over rock, is usually of harder surface, if not of ice. Hence we have to allow for a sudden and surprising acceleration just where we intended to slow up.

No man should start glissading down a gully or slope that he does not know; or that he cannot see throughout its whole length; or until he is expert enough to know what the snow, as he finds it, will do with his feet.

On Grass and Heather.

Glissading is also possible and pleasant on slopes of grass, heather or whortleberry growth, if the angle of the hill is steep and the conditions right.

Under snow, even in small quantity or half melted, any herbage will serve; but the dry, polished, almost glassy surface of grass or short growth, produced by drought or hot sun, is almost as slippery as snow.

On firm covering snow over hill grass, of course a standing glissade is indicated.

If the snow is soft or thin, so that the feet would catch through it upon the grass or heather stems, sitting is best. On steep slopes sitting means rapid going, while there is any snow at all showing between the stalks.

If the snow is merely a wet skim, or if we are glissading upon dry glassy herbage, it is better for clothes and comfort to use the feet. The correct method is to sit or squat right down on the heels. If we have an axe or stick, we lean back upon it, or push with it, as balance or our relenting pace suggests. If we have no stick, we clasp the hands round the knees and shoot down in a honeypot attitude. At a check, the legs are shot out, and a raking action of the heels starts the slide again. This fashion of sliding crouched upon the feet is feasible upon nearly all steep slopes of smooth, thick, fatiguing herbage, where the walking descent would be slippery and laborious; but it must be used with caution. Stones, roots and hummocks intrude; and nowhere is a human being more helpless, once he has lost control, than on steep, slippery grass. If he once starts to roll, a broken arm or a bad shaking may be the least disagreeable consequence. There have been more serious accidents due to slips on grass than on all the snow mountains of the world put together.
