The work already accomplished was enormous. On the Polar Journey the ponies and dogs could now travel light for the first hundred and thirty geographical miles, when, at One Ton Camp, they would for the first time take their full loads: the advantage of being able to start again with full loads when so far on your way is obvious when it is considered that the distance travelled depends upon the weight of food that can be carried. During the geological journey on the western side of the Sound, Taylor and his party had carried out much useful geological work in Dry Valley and on the Ferrar and Koettlitz Glaciers, which had been accurately plotted for the charts, and had been examined for the first time by an expert physiographer and ice specialist. The ordinary routine of scientific and meteorological observations usual with all Scott's sledging parties was observed.
Further, at Cape Evans there had been running for more than three months a scientific station, which rivalled in thoroughness and exactitude any other such station in the world. I hope that later a more detailed account may be given of this continuous series of observations, some of them demanding the most complex mechanism, and all of them watched over by enthusiastic experts. It must here suffice to say that we who on our return saw for the first time the hut and its annexes completely equipped were amazed; though perhaps the gadget which appealed most to us at first was the electric apparatus by which the cook, whose invention it was, controlled the rising of his excellent bread.
Glad as we were to find it all and to enjoy the food, bath and comfort which it offered, we had no illusions about Cape Evans itself. It is uninteresting, as only a low-lying spit of black lava covered for the most part with snow, and swept constantly by high winds and drift, can be uninteresting. The kenyte lava of which it is formed is a remarkable rock, and is found in few parts of the world: but when you have seen one bit of kenyte you have seen all. Unlike the spacious and lofty Hut Point Peninsula, thirteen miles to the south, it has no outstanding hills and craters; no landmarks such as Castle Rock. Unlike the broad folds of Cape Royds, six miles to the north, it has none of the rambling walks and varied lakes, in which is found most of the limited plant life which exists in these latitudes, and though a few McCormick skuas meet here, there is no nursery of penguins such as that which makes Cape Royds so attractive in summer. Nor has the Great Ice Sheet, which reached up Erebus and spread over the Ross Sea in the past, spilled over Cape Evans in its retreat a wealth of foreign granites, dolerites, porphyrys and sandstone such as cover the otherwise dull surface round Shackleton's old Winter Quarters.
Cape Evans is a low lava flow jutting out some three thousand feet from the face of the glaciers which clothe the slopes of Erebus. It is roughly an equilateral triangle in shape, at its base some three thousand feet (9/16th mile) across. This base-line, which divides the cape from the slopes of Erebus and the crevassed glaciers and giant ice-falls which clothe them, consists of a ramp with a slope of thirty degrees, and a varying height of some 100 to 150 feet. From our hut, four hundred yards away, it looks like a great embankment behind which rises the majestic volcano Erebus, with its plume of steam and smoke.
The cape itself does not rise on the average more than thirty feet, and somewhat resembles the back of a hog with several backbones. The hollows between the ridges are for the most part filled with snow and ice, while in one or two places where the accumulation of snow is great enough there are little glacierets which do not travel far before they ignominiously peter out. There are two small lakes, called Skua Lake and Island Lake respectively. There is only one hill which is almost behind the hut, and is called Wind Vane Hill, for on it were placed one of our wind vanes and certain other meteorological instruments. Into the glacieret which flowed down in the lee of this hill we drove two caves, which gave both an even low temperature and excellent insulation. One of them was therefore used for our magnetic observations, and the other as an ice-house for the mutton we had brought from New Zealand.
The north side, upon which we had built our hut, slopes down by way of a rubbly beach to the sea in North Bay. We knew there was a beach for we landed upon it, but we never saw it again even in the height of summer, for the winter blizzards formed an ice foot several feet thick. The other side of the cape ends abruptly in black bastions and baby cliffs some thirty feet high. The apex of the triangle which forms as it were the cape proper is a similar kenyte bluff. The whole makes a tricky place on which to walk in the dark, for the surface is strewn with boulders of all sizes and furrowed and channelled by drifts of hard and icy snow, and quite suddenly you may find yourself prostrate upon a surface of slippery blue ice. It may be easily imagined that it is no seemly place to exercise skittish ponies or mules in a cold wind, but there is no other place when the sea-ice is unsafe.
Come and stand outside the hut door. All round you, except where the cape joins the mountain, is the sea. You are facing north with your back to the Great Ice Barrier and the Pole, with your eyes looking out of the mouth of McMurdo Sound over the Ross Sea towards New Zealand, two thousand miles of open water, pack and bergs. Look over the sea to your left. It is mid-day, and though the sun will not appear above the horizon he is still near enough to throw a soft yellow light over the Western Mountains. These form the coast-line thirty miles across the Sound, and as they disappear northwards are miraged up into the air and float, black islands in a lemon sky. Straight ahead of you there is nothing to be seen but black open sea, with a high light over the horizon, which you know betokens pack; this is ice blink. But as you watch there appears and disappears a little dark smudge. This puzzles you for some time, and then you realize that this is the mirage of some far mountain or of Beaufort Island, which guards the mouth of McMurdo Sound against such traffic as ever comes that way, by piling up the ice floes across the entrance.
As you still look north, in the middle distance, jutting out into the sea, is a low black line of land, with one excrescence. This is Cape Royds, with Shackleton's old hut upon it; the excrescence is High Peak, and this line marks the first land upon the eastern side of McMurdo Sound which you can see, and indeed is actually the most eastern point of Ross Island. It disappears abruptly behind a high wall, and if you let your eyes travel round towards your right front you see that the wall is a perpendicular cliff two hundred feet high of pure green and blue ice, which falls sheer into the sea, and forms, with Cape Evans, on which we stand, the bay which lies in front of our hut, and which we called North Bay. This great ice-cliff with its crevasses, towers, bastions and cornices, was a never-ending source of delight to us; it forms the snout of one of the many glaciers which slide down the slopes of Erebus: in smooth slopes and contours where the mountain underneath is of regular shape: in impassable icefalls where the underlying surface is steep or broken. This particular ice stream is called the Barne Glacier, and is about two miles across. The whole background from our right front to our right rear, that is from N.E. to S.E., is occupied by our massive and volcanic neighbour, Erebus. He stands 13,500 feet high. We live beneath his shadow and have both admiration and friendship for him, sometimes perhaps tinged with respect. However, there are no signs of dangerous eruptive disturbances in modern times, and we feel pretty safe, despite the fact that the smoke which issues from his crater sometimes rises in dense clouds for many thousands of feet, and at others the trail of his plume can be measured for at least a hundred miles.
If you are not too cold standing about (it does not pay to stand about at Cape Evans) let us make our way behind the hut and up Wind Vane Hill. This is only some sixty-five feet high, yet it dominates the rest of the cape and is steep enough to require a scramble, even now when the wind is calm. Look out that you do not step on the electric wires which connect the wind-vane cups on the hill with the recording dial in the hut. These cups revolve in the wind, the revolutions being registered electrically: every four miles a signal was sent to the hut, and a pen working upon a chronograph registered one more step. There is also a meteorological screen on the summit, which has to be visited at eight o'clock each morning in all weathers.
