An easterly breeze brought cloud and falls of snow during the morning of January 11. The barrier trended south-west by south, and we skirted it for fifty miles until 11 am. The cliffs in the morning were 20 ft. high, and by noon they had increased to 110 and 115 ft. The brow apparently rose 20 to 30 ft. higher. We were forced away from the barrier once for three hours by a line of very heavy pack-ice. Otherwise there was open water along the edge, with high loose pack to the west and north-west. We noticed a seal bobbing up and down in an apparent effort to swallow a long silvery fish that projected at least eighteen inches from its mouth. The noon position was lat. 73° 13´ S., long. 20° 43´ W., and a sounding then gave 155 fathoms at a distance of a mile from the barrier. The bottom consisted of large igneous pebbles. The weather then became thick, and I held away to the westward, where the sky had given indications of open water, until 7 p.m., when we laid the ship alongside a floe in loose pack. Heavy snow was falling, and I was anxious lest the westerly wind should bring the pack hard against the coast and jam the ship. The Nimrod had a narrow escape from a misadventure of this kind in the Ross Sea early in 1908.
We made a start again at 5 a.m. the next morning (January 12) in overcast weather with mist and snow-showers, and four hours later broke through loose pack-ice into open water. The view was obscured, but we proceeded to the south-east and had gained 24 miles by noon, when three soundings in lat. 74° 4´ S., long. 22° 48´ W. gave 95, 128, and 103 fathoms, with a bottom of sand, pebbles, and mud. Clark got a good haul of biological specimens in the dredge. The Endurance was now close to what appeared to be the barrier, with a heavy pack-ice foot containing numerous bergs frozen in and possibly aground. The solid ice turned away towards the north-west, and we followed the edge for 48 miles N. 60° W. to clear it.
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.”
The Endurance lay under the lee of the stranded berg until 7 a.m. on January 18. The gale had moderated by that time, and we proceeded under sail to the south-west through a lane that had opened along the glacier-front. We skirted the glacier till 9.30 a.m., when it ended in two bays, open to the north-west but sheltered by stranded bergs to the west. The coast beyond trended south-south-west with a gentle land-slope.
“The pack now forces us to go west 14 miles, when we break through a long line of heavy brash mixed with large lumps and ‘growlers’ We do this under the fore-topsail only, the engines being stopped to protect the propeller. This takes us into open water, where we make S. 50° W. for 24 miles. Then we again encounter pack which forces us to the north-west for 10 miles, when we are brought up by heavy snow-lumps, brash, and large, loose floes. The character of the pack shows change. The floes are very thick and are covered by deep snow. The brash between the floes is so thick and heavy that we cannot push through without a great expenditure of power, and then for a short distance only. We therefore lie to for a while to see if the pack opens at all when this north-east wind ceases.”
Our position on the morning of the 19th was lat. 76° 34´ S., long. 31° 30´ W. The weather was good, but no advance could be made. The ice had closed around the ship during the night, and no water could be seen in any direction from the deck. A few lanes were in sight from the mast-head. We sounded in 312 fathoms, finding mud, sand, and pebbles. The land showed faintly to the east. We waited for the conditions to improve, and the scientists took the opportunity to dredge for biological and geological specimens. During the night a moderate north-easterly gale sprang up, and a survey of the position on the 20th showed that the ship was firmly beset. The ice was packed heavily and firmly all round the Endurance in every direction as far as the eye could reach from the masthead. There was nothing to be done till the conditions changed, and we waited through that day and the succeeding days with increasing anxiety. The east-north-easterly gale that had forced us to take shelter behind the stranded berg on the 16th had veered later to the north-east, and it continued with varying intensity until the 22nd. Apparently this wind had crowded the ice into the bight of the Weddell Sea, and the ship was now drifting south-west with the floes which had enclosed it. A slight movement of the ice round the ship caused the rudder to become dangerously jammed on the 21st, and we had to cut away the ice with ice-chisels, heavy pieces of iron with 6-ft. wooden hafts. We kept steam up in readiness for a move if the opportunity offered, and the engines running full speed ahead helped to clear the rudder. Land was in sight to the east and south about sixteen miles distant on the 22nd. The land-ice seemed to be faced with ice-cliffs at most points, but here and there slopes ran down to sea-level. Large crevassed areas in terraces parallel with the coast showed where the ice was moving down over foot-hills. The inland ice appeared for the most part to be undulating, smooth, and easy to march over, but many crevasses might have been concealed from us by the surface snow or by the absence of shadows. I thought that the land probably rose to a height of 5000 ft. forty or fifty miles inland. The accurate estimation of heights and distances in the Antarctic is always difficult, owing to the clear air, the confusing monotony of colouring, and the deceptive effect of mirage and refraction. The land appeared to increase in height to the southward, where we saw a line of land or barrier that must have been seventy miles, and possibly was even more distant.
Sunday, January 24, was a clear sunny day, with gentle easterly and southerly breezes. No open water could be seen from the mast-head, but there was a slight water-sky to the west and north-west. “This is the first time for ten days that the wind has varied from north-east and east, and on five of these days it has risen to a gale. Evidently the ice has become firmly packed in this quarter, and we must wait patiently till a southerly gale occurs or currents open the ice. We are drifting slowly. The position to-day was 76° 49´ S., 33° 51´ W. Worsley and James, working on the floe with a Kew magnetometer, found the variation to be six degrees west.” Just before midnight a crack developed in the ice five yards wide and a mile long, fifty yards ahead of the ship. The crack had widened to a quarter of a mile by 10 a.m. on the 25th, and for three hours we tried to force the ship into this opening with engines at full speed ahead and all sails set. The sole effect was to wash some ice away astern and clear the rudder, and after convincing myself that the ship was firmly held I abandoned the attempt. Later in the day Crean and two other men were over the side on a stage chipping at a large piece of ice that had got under the ship and appeared to be impeding her movement. The ice broke away suddenly, shot upward and overturned, pinning Crean between the stage and the haft of the heavy 11-ft. iron pincher. He was in danger for a few moments, but we got him clear, suffering merely from a few bad bruises. The thick iron bar had been bent against him to an angle of 45 degrees.
The days that followed were uneventful. Moderate breezes from the east and south-west had no apparent effect upon the ice, and the ship remained firmly held. On the 27th, the tenth day of inactivity, I decided to let the fires out. We had been burning half a ton of coal a day to keep steam in the boilers, and as the bunkers now contained only 67 tons, representing thirty-three days’ steaming, we could not afford to continue this expenditure of fuel. Land still showed to the east and south when the horizon was clear. The biologist was securing some interesting specimens with the hand-dredge at various depths. A sounding on the 26th gave 360 fathoms, and another on the 29th 449 fathoms. The drift was to the west, and an observation on the 31st (Sunday) showed that the ship had made eight miles during the week. James and Hudson rigged the wireless in the hope of hearing the monthly message from the Falkland Islands. This message would be due about 3.20 a.m. on the following morning, but James was doubtful about hearing anything with our small apparatus at a distance of 1630 miles from the dispatching station. We heard nothing, as a matter of fact, and later efforts were similarly unsuccessful. The conditions would have been difficult even for a station of high power.
