The Worst Journey in the World - Apsley Cherry-Garrard (online e reader .txt) 📗

any means smooth. “I was much disturbed last night by the motion; the ship was pitching and twisting with short sharp movements on a confused sea, and with every plunge my thoughts flew to our poor ponies. This afternoon they are fairly well, but one knows that they must be getting weaker as time goes on, and one longs to give them a good sound rest with a ship on an even keel. Poor patient beasts! One wonders how far the memory of such fearful discomfort will remain with them⁠—animals so often remember places and conditions where they have encountered difficulties or hurt. Do they only recollect circumstances which are deeply impressed by some shock of fear or sudden pain, and does the remembrance of prolonged strain pass away? Who can tell? But it would seem strangely merciful if nature should blot out these weeks of slow but inevitable torture.”50

On December 7, noon position 61° 2′ S., 179° 6′ W., one berg was sighted far away to the west, as it gleamed every now and then in the sun. Two more were seen the next day, and at 6:22 a.m. on December 9, noon position 65° 8′ S., 177° 1′ W., the pack was sighted ahead by Rennick. All that day we passed bergs and streams of ice. The air became dry and bracing, the sea was calm, and the sun shining on the islands of ice was more than beautiful. And then Bump! We had just charged the first big floe, and we were in the pack.

“The sky has been wonderful, with every form of cloud in every condition of light and shade; the sun has continually appeared through breaks in the cloudy heavens from time to time, brilliantly illuminating some field of pack, some steep-walled berg, or some patch of bluest sea. So sunlight and shadow have chased each other across our scene. Tonight there is little or no swell⁠—the ship is on an even keel, steady, save for the occasional shocks on striking ice.

“It is difficult to express the sense of relief this steadiness gives after our storm-tossed passage. One can only imagine the relief and comfort afforded to the ponies, but the dogs are visibly cheered and the human element is full of gaiety. The voyage seems full of promise in spite of the imminence of delay.”51

We had met the pack farther north than any other ship.

What is pack? Speaking very generally indeed, in this region it is the sea-ice which forms over the Ross Sea area during the winter, and is blown northwards by the southerly blizzards. But as we shall see, the ice which forms over this area is of infinite variety. As a rule great sheets spread over the seas which fringe the Antarctic continent in the autumn, grow thicker and thicker during the winter and spring, and break up when the temperatures of sea and air rise in summer. Such is the ice which forms in normal seasons round the shores of McMurdo Sound, and up the coast of the western mountains of Victoria Land. In sheltered bays this ice will sometimes remain in for two years or even more, growing all the time, until some phenomenal breakup releases it. We found an example of this in the sea-ice which formed between Hut Point and the Barrier. But there are great waters which can never freeze for very long. Cape Crozier, for instance, where the Emperor penguins nest in winter, is one of the windiest places in the world. In July it was completely frozen over as far as we could see in the darkness from a height of 900 feet. Within a few days a hurricane had blown it all away, and the sea was black.

I believe, and we had experiences to prove me right, that there is a critical period early in the winter, and that if sea-ice has not frozen thick enough to remain fast by that time, it is probable that the sea will remain open for the rest of the year. But this does not mean that no ice will form. So great is the wish of the sea to freeze, and so cold is the air, that the wind has only to lull for one instant and the surface is covered with a thin film of ice, as though by magic. But the next blizzard tears it out by force or a spring tide coaxes it out by stealth, whether it be a foot thick or only a fraction of an inch. Such an example we had at our very doors during our last winter, and the untamed winds which blew as a result were atrocious.

Thus it is that floes from a few inches to twenty feet thick go voyaging out to join the belt of ice which is known as the pack. Scott seems to have thought that the whole Ross Sea freezes over.52 I myself think this doubtful, and I am, I believe, the only person living who has seen the Ross Sea open in midwinter. This was on the Winter Journey undertaken by Wilson, Bowers and myself in pursuit of Emperor penguin eggs⁠—but of that later.

It is clear that winds and currents are, broadly speaking, the governing factors of the density of pack-ice. By experience we know that clear water may be found in the autumn where great tracts of ice barred the way in summer. The tendency of the pack is northwards, where the ice melts into the warmer waters. But the bergs remain when all traces of the pack have disappeared, and, drifting northwards still, form the menace to shipping so well known to sailors rounding the Horn. It is not hard to imagine that one monster ice island of twenty miles in length, such as do haunt these seas, drifting into navigated waters and calving into hundreds of great bergs as it goes, will in itself produce what
