Ernest Henry Shackleton - South! The Story of Shackleton's Last Expedition, 1914-1917; Includes both text and audio files

Now we were beyond the point reached by the Scotia , and the land underlying the ice-sheet we were skirting was new. The northerly trend was unexpected, and I began to suspect that we were really rounding a huge ice-tongue attached to the true barrier-edge and extending northward. Events confirmed this suspicion. We skirted the pack all night, steering north-west; then went west by north till 4 a.m. and round to south-west. The course at 8 a.m. on the 13th was south-south-west. The barrier at midnight was low and distant, and at 8 a.m. there was merely a narrow ice-foot about two hundred yards across separating it from the open water. By noon there was only an occasional shelf of ice-foot. The barrier in one place came with an easy sweep to the sea. We could have landed stores there without difficulty. We made a sounding 400 ft. off the barrier but got no bottom at 676 fathoms. At 4 p.m., still following the barrier to the south-west, we reached a corner and found it receding abruptly to the south-east. Our way was blocked by very heavy pack, and after spending two hours in a vain search for an opening, we moored the Endurance to a floe and banked fires. During that day we passed two schools of seals, swimming fast to the north-west and north-north-east. The animals swam in close order, rising and blowing like porpoises, and we wondered if there was any significance in their journey northward at that time of the year. Several young emperor penguins had been captured and brought aboard on the previous day. Two of them were still alive when the Endurance was brought alongside the floe. They promptly hopped on to the ice, turned round, bowed gracefully three times, and retired to the far side of the floe. There is something curiously human about the manners and movements of these birds. I was concerned about the dogs. They were losing condition and some of them appeared to be ailing. One dog had to be shot on the 12th. We did not move the ship on the 14th. A breeze came from the east in the evening, and under its influence the pack began to work off shore. Before midnight the close ice that had barred our way had opened and left a lane along the foot of the barrier. I decided to wait for the morning, not wishing to risk getting caught between the barrier and the pack in the event of the wind changing. A sounding gave 1357 fathoms, with a bottom of glacial mud. The noon observation showed the position to be lat. 74° 09´ S., long. 27° 16´ W. We cast off at 6 a.m. on the 15th in hazy weather with a north-easterly breeze, and proceeded along the barrier in open water. The course was south-east for sixteen miles, then south-south-east. We now had solid pack to windward, and at 3 p.m. we passed a bight probably ten miles deep and running to the north-east. A similar bight appeared at 6 p.m. These deep cuts strengthened the impression we had already formed that for several days we had been rounding a great mass of ice, at least fifty miles across, stretching out from the coast and possibly destined to float away at some time in the future. The soundings—roughly, 200 fathoms at the landward side and 1300 fathoms at the seaward side—suggested that this mighty projection was afloat. Seals were plentiful. We saw large numbers on the pack and several on low parts of the barrier, where the slope was easy. The ship passed through large schools of seals swimming from the barrier to the pack off shore. The animals were splashing and blowing around the Endurance , and Hurley made a record of this unusual sight with the kinematograph-camera.

The barrier now stretched to the south-west again. Sail was set to a fresh easterly breeze, but at 7 p.m. it had to be furled, the Endurance being held up by pack-ice against the barrier for an hour. We took advantage of the pause to sound and got 268 fathoms with glacial mud and pebbles. Then a small lane appeared ahead. We pushed through at full speed, and by 8.30 p.m. the Endurance was moving southward with sails set in a fine expanse of open water. We continued to skirt the barrier in clear weather. I was watching for possible landing-places, though as a matter of fact I had no intention of landing north of Vahsel Bay, in Luitpold Land, except under pressure of necessity. Every mile gained towards the south meant a mile less sledging when the time came for the overland journey.

Shortly before midnight on the 15th we came abreast of the northern edge of a great glacier or overflow from the inland ice, projecting beyond the barrier into the sea. It was 400 or 500 ft. high, and at its edge was a large mass of thick bay-ice. The bay formed by the northern edge of this glacier would have made an excellent landing-place. A flat ice-foot nearly three feet above sea-level looked like a natural quay. From this ice-foot a snow-slope rose to the top of the barrier. The bay was protected from the south-easterly wind and was open only to the northerly wind, which is rare in those latitudes. A sounding gave 80 fathoms, indicating that the glacier was aground. I named the place Glacier Bay, and had reason later to remember it with regret.

The Endurance steamed along the front of this ice-flow for about seventeen miles. The glacier showed huge crevasses and high pressure ridges, and appeared to run back to ice-covered slopes or hills 1000 or 2000 ft. high. Some bays in its front were filled with smooth ice, dotted with seals and penguins. At 4 a.m. on the 16th we reached the edge of another huge glacial overflow from the ice-sheet. The ice appeared to be coming over low hills and was heavily broken. The cliff-face was 250 to 350 ft. high, and the ice surface two miles inland was probably 2000 ft. high. The cliff-front showed a tide-mark of about 6 ft., proving that it was not afloat. We steamed along the front of this tremendous glacier for 40 miles and then, at 8.30 a.m., we were held up by solid pack-ice, which appeared to be held by stranded bergs. The depth, two cables off the barrier-cliff, was 134 fathoms. No further advance was possible that day, but the noon observation, which gave the position as lat. 76° 27´ S. long. 28° 51´ W., showed that we had gained 124 miles to the south-west during the preceding twenty-four hours. The afternoon was not without incident. The bergs in the neighbourhood were very large, several being over 200 ft. high, and some of them were firmly aground, showing tidemarks. A barrier-berg bearing north-west appeared to be about 25 miles long. We pushed the ship against a small banded berg, from which Wordie secured several large lumps of biotite granite. While the Endurance was being held slow ahead against the berg a loud crack was heard, and the geologist had to scramble aboard at once. The bands on this berg were particularly well defined; they were due to morainic action in the parent glacier. Later in the day the easterly wind increased to a gale. Fragments of floe drifted past at about two knots, and the pack to leeward began to break up fast. A low berg of shallow draught drove down into the grinding pack and, smashing against two larger stranded bergs, pushed them off the bank. The three went away together pell-mell. We took shelter under the lee of a large stranded berg.

A blizzard from the east-north-east prevented us leaving the shelter of the berg on the following day (Sunday, January 17). The weather was clear, but the gale drove dense clouds of snow off the land and obscured the coast-line most of the time. “The land, seen when the air is clear, appears higher than we thought it yesterday; probably it rises to 3000 ft. above the head of the glacier. Caird Coast, as I have named it, connects Coats’ Land, discovered by Bruce in 1904, with Luitpold Land, discovered by Filchner in 1912. The northern part is similar in character to Coats’ Land. It is fronted by an undulating barrier, the van of a mighty ice-sheet that is being forced outward from the high interior of the Antarctic Continent and apparently is sweeping over low hills, plains, and shallow seas as the great Arctic ice-sheet once pressed over Northern Europe. The barrier surface, seen from the sea, is of a faint golden brown colour. It terminates usually in cliffs ranging from 10 to 300 ft. in height, but in a very few places sweeps down level with the sea. The cliffs are of dazzling whiteness, with wonderful blue shadows. Far inland higher slopes can be seen, appearing like dim blue or faint golden fleecy clouds. These distant slopes have increased in nearness and clearness as we have come to the south-west, while the barrier cliffs here are higher and apparently firmer. We are now close to the junction with Luitpold Land. At this southern end of the Caird Coast the ice-sheet, undulating over the hidden and imprisoned land, is bursting down a steep slope in tremendous glaciers, bristling with ridges and spikes of ice and seamed by thousands of crevasses. Along the whole length of the coast we have seen no bare land or rock. Not as much as a solitary nunatak has appeared to relieve the surface of ice and snow. But the upward sweep of the ice-slopes towards the horizon and the ridges, terraces, and crevasses that appear as the ice approaches the sea tell of the hills and valleys that lie below.”
