(The following analysis of the authors' attempt on Peak 36, in the Saltoro Karakoram, during June 1935, should be studied together with the account of the climb which was published in Himalayan Journal, vol. viii, 1936. The text below is by John Hunt, the Appendixes by James Waller.)
The summits of Peak 35 (25,280 feet) and Peak 36 (25,400 feet)14 lie on a great ridge whose approximate orientation is NW.-SE. From the southern side of this ridge a tremendous rock-face falls some 10,000 feet towards the Sherpigang glacier, while the northern side, less steep and, in general, heavily glaciated, falls to the basin of the Peak 36 glacier, directly south of the junction of this glacier with the Siachen. From the summit of the lower peak the ridge descends precipitously towards the north-west in a series of steps occasioned by the strata, but the south-east continuation maintains a gentle gradient almost throughout its length. Except for two prominent buttresses thrown out on the N. and NE. sides of the peak, there are no other ridges.
The Approaches.
From the south the natural approach to the foot of the south face is by the Kondus Nala and the Sherpigang glacier, three of whose feeder glaciers flow directly from the foot of this precipice.
From the north the Peak 36 glacier may be reached by ascending the Siachen glacier through the greater part of its length, and thus access is gained to the northern and eastern sides of Peak 36. As the natural approach of any expedition from Kashmir will be from the south, however, the problem of reaching the Peak 36 glacier from this direction has to be faced. There are three alternative routes:
The course taken by this glacier, first revealed by our No. 1 reconnaissance (Waller and Da Tondrup), offers the most direct and the least difficult route to the only vulnerable points of Peak 36, and is therefore the route which we strongly recommend to future parties. It is, however, free of neither difficulty nor danger.
The second 'arm' of this glacier, whose nullah is known locally as the Likah, contains a considerable ice-fall (2,500 feet), up which coolies should not be taken. It can be avoided by taking to the true right (W.) bank, and reaching a col (Likah col, 18,000 feet) whence a steep descent of some 700 feet is made on to the easy upper reaches of the Likah glacier, and above the head of the ice-fall.
Footnote
This col will normally be heavily corniced on its far or east side, and though the uniformity of the slope below is broken by outcrops of rock, its general angle makes it a troublesome place for coolies, and the difficulty and the element of danger are increased when conditions are bad. A long fixed line is necessary for this passage. We were caught by a blizzard during the descent of this slope, and it was five days before all the loads were brought down from the col. Future parties are advised to carry all the loads down, and not to attempt throwing or lowering under any circumstances; the irregularities of the slope are against such tactics.
Although the technical difficulties of the ascent are at an end after circumventing the ice-fall, it may be dangerous after crossing the foot of the SE. ridge. The eastern face is broken some 2,000 feet above its base by an almost uninterrupted line of ice-cliffs, which are in a continual state of disintegration, and their base, from the foot of the SE. ridge to the Bilafond Wall, and round the edges of the Peak 36 glacier, will be found strewn with ice-blocks.
A detour can be made to avoid much of this danger, but the only easy passage of the Bilafond Wall is at its junction with the mountain face, and at this point avalanches are particularly active. At least three falls of colossal dimensions occurred here during our stay, one of which we witnessed; not only did the debris sweep both sides of the col by which we crossed, but the mass of ice-blocks poured out into the level basin of the Peak 36 glacier for a distance of over 500 yards. For this reason, this col can never be used as a regular coolie route, which means that, if the Likah route is taken, the Base Camp of an expedition cannot be on the Peak 36 glacier. As the exposure to ice avalanches is experienced soon after crossing the SE. ridge, it is felt that the site of our Base Camp, at the head of the Likah glacier and at the foot of the rocks of the SE. ridge itself, is an ideal one.
Route of Ascent.
The NW. ridge, descending from the summit of Peak 36, need not be considered as a climbing proposition at that altitude. Apart from its general angle and exposure, which would make it difficult to establish camps on it, the strata lie to the climber's disadvantage.
No more promising is the south face, an imposing rock precipice, which, though relieved by bands of snow, indicating changes in gradient, would not be climbable in the Himalaya. The only vulnerable features of the mountain are, in fact, the SE. ridge and the E. (or ENE.) face.
Attention is at once drawn to the attractive slope of the SE. ridge, curving down from the summit of Peak 36 until about 1,500 feet above its foot. Here its uniformity is interrupted by some 300 feet of crumbling ice-cliff (corresponding with the line of ice-cliffs continuing from this point along the east face), below which it terminates, in about half a mile, in an arete of red granite. The existence of this ice-cliff, which we actually watched breaking away during our stay at the base, makes it inevitable that the ridge can be used only above this point. It would in the Alps be an ice problem of the first magnitude, without the added difficulty of altitude and camps. An attempt to reach the head of the rock arete immediately below the cliff I lowed that considerable labour in step-cutting would be entailed, ind therefore ropes fixed for coolies, before the crucial pitch was reached; and ice is tough at that height. Moreover, the possibility of the ice-cliff falling away during or after the passage of the party rules it out as a route.
There remains, therefore, the problem of striking the SE. ridge above the ice-cliffs. As explained, this is not feasible on the southern side, but the solution lies in the face falling on to the Peak 36 glacier. After crossing the Bilafond Wall, and skirting the foot of the face for about a mile, the base of a great shelf of ice is reached, some 2,000 feet in height and projecting into the glacier basin. Above this shelf is the only break in the line of ice-cliffs between the SE. ridge and the NE. buttress, and it was at the higher end of the shelf that our Camp V (20,000 feet) was pitched. For some 2,000 feet above the shelf the ground, corresponding with the line of ice-cliffs on either hand, is very steep and broken, and it is here that most of the technical difficulties are met. Above 22,000 feet the angle eases, the crest of the SE. ridge is reached, and the way to the summit clear. I feel certain that this route, practicable in 1935, may alter considerably and frequently. The existence of three immense vertical crevasses splitting the steepest slope encountered (800 feet, some of it being steeper than 60 °), leads me to suspect that this section is likely to disappear, and with it the key to the climb. Immediately above it we found our track, made during the reconnaissance on the previous day, swept by a large fall of seracs—another instance of disintegration and change. On the other hand, the same forces which bring about these changes may make the same line easier, or, in closing that line, open up a route elsewhere. However it may be, I should not expect, another year, to be faced with passages in any way similar to those by which we ascended in 1935.
Weather and Snow Conditions.
Our first experience of bad weather was during the reconnaissances which took place from the 14th to the 20th May. Only one of these days, the 18th, was clear, snow, wind, and cloud making much of the work trying and difficult on the remaining days. Another period of bad weather, from the 20th to the 23rd May, was followed by only two fine days, the 24th and 25th, by which time we had established Camp II below the Likah col. A blizzard started about midday on the 26th, forcing us to make an involuntary camp in an exposed position on the Likah col, and this continued for five days (26^1-31 st incl.), causing severe discomfort, disorganizing the lowering of loads from the col to the glacier, and burying certain equipment, not to be recovered, under some three feet of fresh snow.
Between the 1st and 8th June we were treated to fair weather, but it was noticed that this invariably deteriorated about midday, by which time heavy clouds had rapidly blown up from the south, and snow fell for an hour or so every afternoon, sometimes not ceasing until evening. This was, of course, a serious handicap to our work, and curtailed an attempt by Waller and myself on the SE. ridge.
The second blizzard started on the 9th, and continued for four days (9th-i2th incl.). We had a typical half-clear day on the 13th, when Brotherhood rejoined us from the Bilafond.
A very clear morning on the 14th June decided us to proceed to Camp IV (at the foot of the shelf on the Peak 36 glacier). By 2 p.m., however, it was snowing, and by evening a blizzard was in progress. This continued uninterrupted till about midday on the 16th, when a sudden clearing permitted a short reconnaissance towards the lip of the shelf. The party concerned (Hunt and Pal ten) ploughed waist-deep in new snow, all of it in a dangerous condition on sleeper slopes, and an avalanche was dislodged. Light snow-fall then set in, and it was not clear when half the party set out on the 17th to establish Camp V; indeed, snow fell heavily until about 11 a.m., almost persuading them to give up the attempt. It cleared completely that evening, and the 18th and 19th were perfect days. We were at Camp VI by the evening of the 19th, in high hopes of reaching the summit next day. During this period the wind blew steadily from the east. The morning of the 20th was cloudless, but a change was noticed at about 11 a.m.4 A rim of clouds was seen rising beyond the Great Karakoram, and from then onwards conditions rapidly deteriorated. Clouds were seen blowing up over the SE. ridge from the south, and pouring over the Bilafond Wall into the Peak 36 glacier basin. Shortly before reaching the ridge we were met by blinding snow, and clouds were by now all round us. This was the prelude to the fourth blizzard, which set in during the night of the 20th, and continued, as far as we could judge, till the 24th.
It was noticeable that, in the periods of fair weather, the afternoon snow-storms affected only the south side of the peak, from which direction all the bad weather came. Practically the only completely clear days we had were 8th June, when Waller and I camped on Peak 36 glacier (heavy clouds surrounded the peak, but we were unaffected), and 18th and 19th June, during the assault.
Snow Conditions.
The conditions resulting from the two-days' blizzard which held us up in Camp IV could hardly have been worse. The fact that the prevailing wind, and that which brought all our bad weather, blew from the south, resulted in a very heavy snow deposit on the northern and eastern sides of the mountain. It no doubt also accounts for the glaciated condition of this face of Peak 36, in contrast to the bare, rocky aspect of the south face.
The state of the snow on the 17th and 18th June, when we moved to Camp V and continued the route further up the face, falls into a category described by G. W. Young in Mountain Craft. His words fit so exactly both its nature and the manner in which we struggled up it, that I quote:
Frothy snow, neither powdery nor wet ... is safe at almost any angle if it lies on a good sub-surface. But it is infinitely laborious. A step takes us up to our waist or shoulders. Progress is only possible by flogging a furrow up it with forearms and shins, which leaves a trail like an ecstatic sea-serpent. Some relief may be got by slapping down the shaft of the axe flatwise above us and crosswise to the line of advance, and pulling up on it as on a horizontal bar.
It only remains to add that we experienced these conditions between 18,000 and 22,000 feet, that certain slopes were inclined at rather more than 60and that we carried loads of 20 lb. each. On one slope, immediately above Camp V, the snow lay about 15 inches deep on ice. To have cleared the whole surface in order to cut steps in the ice would have been terribly exhausting work, but on the other hand it was only by levering with the arms forced up to the shoulder in the snow above him, that the leader was able to progress upwards without breaking through each step.
On the 19th, while moving up ground already tracked the day before, we dislodged two wind-slab avalanches. The depth of one was not more than eight inches, and this knocked over only the second man; but the other slide was a more serious affair, its blocks being at least a foot thick. Between these occurrences we had, of necessity, to pass over wind-slabbed snow which, though it bore us on the ascent that day, had of its own accord avalanched by the time of our descent some 30 hours later.
Above Camp VI the ground was, in a few places only, steep enough to avalanche, but we had to make one upward traverse on a steep slope in a thoroughly dangerous condition—it fortunately held. The height of this wind-slabbed slope was about 23,000 feet; and as it was under the lee of the SE. ridge it was sheltered from the wind blowing from the south.
The great interest of these details lies in the fact that wind-slab conditions had set in during the night of the 18th June, although no new snow fell during that time, and, as we could see from our tracks of the day before, there was not much deposit of blown snow. A wind sprang up during the night in question, which disturbed us in Camp V, and it therefore appears that the layer of snow deposited during the blizzard of the 14th to 16th June, though unquestionably safe on the 18th, was rendered unsafe by the superficial hardening action of the wind. Certainly wind action had very markedly altered the surface of the slopes up which our tracks had been made the day before.
Surely this brings into question the whole accepted theory as to the formation of wind-slabs? I should like to know what Mr. Arnold Lunn would have to say about this, for the slopes in question were not sheltered from the wind (the wind was blowing from the east till the 20th June and the whole surface was exposed to it); nor had there been any considerable new deposit on slopes which had been safe on the 18th.
On the Likah and Peak 36 glaciers, owing to the frequent snow-fall, typical spring conditions (marble-crust, &c.) were hardly met with. There were normally about three inches of new-fallen snow on a hard, or breakable, crust.
Conclusion.
Up to a height of over 22,000 feet the ascent of the east face of Peak 36 may be considered to be a snow and ice expedition of the first order. The formation of this face gives but small latitude in the line of advance; the severe angle of some of the slopes renders them troublesome in some conditions, dangerous in others. Moreover, this ground is considerably crevassed, and, as we experienced, exposed to falls of seracs from the bordering ice-cliffs, at one point at any rate. We found it advisable to fix one line on the slope giving access to the lip of the shelf (which, besides being very steep, was cut by an improperly bridged schrund), and another to simplify the descent of an immense crevasse which gave us some trouble below Camp VI. Parties establishing a Camp VII, and therefore bringing more porters over the difficult ground between V and VI, will certainly need to fix other ropes as well. Though crampons were not used on the assault itself, I feel that the long slope immediately above Camp V may well be in ice in settled weather conditions, in which case they might be useful. On the other hand, as steps would have to be cut in any case for porters, I think they do not justify the risk of frostbite entailed.
There is no doubt that four camps are required between the foot of the face and the summit, unless conditions are so much improved as to enable a future party to carry Camp VI at least 800 feet above the site taken by us. Waller's plan, excellent in every detail, allowed for this Camp VII, as also for two successive assaults on the summit, and a proper system of support from each camp. His calculations were upset by the weather, and the scheme was modified to an attempt from Camp VI, and by one assault party only, for this reason alone. As events proved, the change was entirely justified, but it must be clearly understood that in normal conditions it would be foolish to attempt to reach the summit from a camp placed below 23,000 feet; for it must be remembered that, in addition to vertical height, there is, as on Everest, a considerable horizontal distance to be covered.

Comments on Tents.
Tent-pegs.
Only (a) used on Peak 36.
Sleeping-bags.
Europeans and porters. Double eiderdown type supplied by Burns. Weight 7 lb. The outer bag of oiled material was unsatisfactory owing to condensation; might well substitute a windproof bag. Possible extra 4 inches width advisable for large men.
Cooks. A rezai bag of similar design to Burns eiderdown bag. Weight 20 lb. (approx.). Cost Rs. 25. Satisfactory.
A wolf-skin bag, canvas-covered. Weight 15 to 18 lb. CostRs. 35 without cover. Requires additional blankets on snow. (N.B. This bag was actually used by myself up to 20,000 feet on Nun Kun, without blankets, but was not comfortable.)
Coolies. Twenty army blankets for seven coolies living in one tent. Cost Rs. 2/8 each second-hand in the bazaar in the Plains. Satisfactory.
Mattresses.
‘Li-Lo' pneumatic mattresses. Weight 3I lb. The standard model is apt to puncture, but the makers, C. B. Cow, Streatham Common, London, can provide special mountaineering models, which have been used in the Arctic. The insulation provided by the 'Li-Los' proved excellent, and their light weight and small bulk when deflated made them most easy to carry.
Cork mattresses. Borrowed from the Himalayan Club. Too bulky for higher transport.
Rezai mattresses. Cost about Rs. 5. Too bulky.
Boots.
Type. Probably any good type of Alpine boot i§ adequate. Unlined boots must be big enough to take three pairs of thick socks. Feet are apt to swell, with the result that boots which are big enough to take three pairs of socks at the beginning of a climb are uncomfortably cramped for two pairs at the end.
Nails. Nailing planned to reduce the conduction of heat from the feet proved unsuitable, owing to the penetration of the nails being insufficient to hold them in the soles. As many as 50 per cent, of the nails in a boot were lost during the first day on the moraine.
Non-freezing boots. Non-freezing boots were found unsatisfactory. A hot sun on the snow-fields resulted in permanently moist boots. The leather absorbed moisture which froze, so that although the leather may not have frozen, the result was identical. Wool-lined boots would probably also be unsatisfactory, as they would be difficult to dry out. We did not use them.
Porters. Porters should be given good boots. In our opinion a European- made boot costing at least £1 ioj. is advisable.
Frost-bite. To guard against frost-bite in deep snow Dr. Longstaff advises Wrapping pieces of blanket outside the boots, or making an external blanket boot.
Windproofs.
A good windproof was made from Silver and Edgington's Aero-wing canvas, at a cost of about £1 per suit. It is very light and of small bulk. Caution should be used in the employment of Aero-wing, and for exceptionally high winds a heavier material would be advisable.
Clothing—Europeans.
Type | Remarks |
Shetland-wool sweaters Woollen underclothing | 3 or 4 each (Lawrie, London). |
Woollen socks | 3 pairs to wear by day; 2 dry pairs by night + spares. |
Thick sweaters | 1 each. Wool with the natural oil still present. (Asdoo, Srinagar, Rs. 5.) Heavy for high altitudes. |
Woollen gloves | Natural wool (Asdoo). A woollen glove alone is usually adequate, and even if snow-coated it retains the warmth in the hand. Quick wearing, so that spares are very necessary. |
Gauntlets | Reinforced windproof material. (Leather freezes.) |
Trousers | Anything from cord to ski-trousers, or even grey flannels. Looseness at waist and knees essential. (Worn under wind- proofs.) |
Short puttees | Kashmir puttoo. Very elastic. |
Maximum clothing worn at any one time:
Drill shirt. | Flannel vest. |
Long woollen pants and vest. | Windproof suit with hood. |
3 pairs socks. | Balaclava helmet. |
3 Shetland wool sweaters. | 2 pairs gloves. |
Cord breeches. | Boots. |
Thick sweater. | Remarks |
Clothing—Cooks, Porters, and Permanent Coolies.
The March | The Climb |
1 warm suit. | 3 pairs socks. |
2 pairs chaplis. | 1 or 2 thick sweaters. |
3 2 pairs leather socks. | Underclothes. Woollen gloves and gauntlets. Windproofs. Boots. |
Goggles. Coolies were supplied with sun-glasses costing 5 annas in Srinagar. A Swiss-type goggle would have been more satisfactory.
Boots—Temporary Coolies. They used their own hide boots made locally. Mending material was supplied by us.
Skis. Proved very useful for reconnaissance purposes.
Crampons. Were rarely used owing to the quantity of new snow.
Sledge. Arctic pattern, fitted with ski-runners, proved a failure for the same reason.
Snow Shoes. Canadian pattern were taken but not used.
Cooking Equipment.
Up to and including Base Camp: 3 Primus stoves.
For the assault: | 1 Demon stove for coolies. 3 No. 80 Meta stoves. 9 Tommy cookers. |
Fuel
18 gallons kerosene (paraffin): Insufficient owing to forced leaking and having no soldering-tools. A small soldering-iron and some resin-cored solder would have been invaluable. (Weight lb.)
To avoid forced leaking, oil-tins should be opened every 2,000 feet rise. 2 petrol tins in one crate, locked, facilitate this.
50 boxes of 50 Meta tablets.
10 Tommy cookers.
Wood.
Note. Throughout the Kabru climb Mr. Cooke used a small Primus stove, for which he invented an aluminium protective shield, holding two saucepans one above the other. The resulting forced draught economized fuel, and altitude to 22,000 feet seemed to have little effect on the working of the stove.

A saving can sometimes be made by obtaining remission of Indian customs duties. This does not appear to be simple for climbers resident in India, although the privilege is sometimes granted to expeditions visiting the Himalayas from Europe.

APPENDIXES V
PHOTOGRAPHY
Camera.
Any good type of hand camera gives good results. A Zeiss Contax or Leitz Leica, with automatic focusing, interchangeable lenses, automatic film winding, focal plane shutter, and using 35 mm. cinema film, is admirable. A comparatively long focal-length lens usually gives the most impressive results, owing to improved perspective.
Films and Filters.
A panchromatic film with a filter makes good photos. A red filter, while rendering the sky too dark, gives the best texture in snow. A yellow filter gives the most 'natural* result, although the increased contrast with a red filter often gives a photograph more expressive of the spirit of the scene. A red filter can often be used with advantage in the Karakoram valleys, where shadows on the great rock walls are thrown into greater relief with the high lights, where the sun meets the faces; while the darkening of the sky to a fairly deep grey tends to emphasize the subject-matter.
Exposure.
A photo-electric meter, used in conjunction with the filter with which the photo is going to be exposed, ensures correct exposure.
A portable dark-room box is valuable in enabling test exposures to be developed on the spot, during rest hours.
Table: Exposure Guide
Circumstances: Month: June. Film: Kodak Panatomic. Time: 10.30 a.m. to 4.0 p.m. Conditions: Normal (i.e. bright sun, figures or tents not too far distant, landscape background).
Normal in Karakoram valleys . . . . | 1/100 sec. at f. 11 |
Normal on snow | 1 /200 sec. at f. 22 |
Distant view with light foreground | ¼ normal exposure |
Portraits, groups .... | 4 times normal |
Dull weather ..... | 4 times normal |
But a light mist on snow | Normal |
All the above are without a filter. A suitable red filter increases the exposure 4 to 10 times according to make and film. A suitable yellow filter with panchromatic film increases the exposure 2 to 4 times.
Sub-standard Cinema Cameras.
It should be realized that the cheap cinema camera is not built for light of such intensity as is found on the Karakoram snows. A deep-red filter, giving an exposure increase of about 10 times, should make all the difference. It is worth noting that, owing to the different emulsion, a red filter which only has a 4-times factor with Panatomic film has a 10-times factor with Kodak Cinema Film (reversible), but a 4-times factor with Supersensitive Cinema Film (reversible). A more expensive type of camera, having variable shutter speeds as well as variable film speeds, as in the Zeiss Movikon and the Kodak Special, may be expected to give the best results.
