South! The Story of Shackleton's Last Expedition, 1914-1917; Includes both text and audio files
before a breeze that only once attained the force of a gale and then for no more than an hour. The absence of strong winds, in comparison with the almost unceasing winter blizzards of the Ross Sea, was a feature of the Weddell Sea that impressed itself upon me during the winter months.
Another race took place a few days after the “Derby.” The two crack teams, driven by Hurley and Wild, met in a race from Khyber Pass. Wild’s team, pulling 910 lbs., or 130 lbs. per dog, covered the 700 yds. in 2 min. 9 sec., or at the rate of 11.1 miles per hour. Hurley’s team, with the same load, did the run in 2 min. 16 sec. The race was awarded by the judge to Hurley owing to Wild failing to “weigh in” correctly. I happened to be a part of the load on his sledge, and a skid over some new drift within fifty yards of the winning post resulted in my being left on the snow. It should be said in justice to the dogs that this accident, while justifying the disqualification, could not have made any material difference in the time.
The approach of the returning sun was indicated by beautiful sunrise glows on the horizon in the early days of July. We had nine hours’ twilight on the 10th, and the northern sky, low to the horizon, was tinted with gold for about seven hours. Numerous cracks and leads extended in all directions to within 300 yds. of the ship. Thin wavering black lines close to the northern horizon were probably distant leads refracted into the sky. Sounds of moderate pressure came to our ears occasionally, but the ship was not involved. At midnight on the 11th a crack in the lead ahead of the Endurance opened out rapidly, and by 2 a.m. was over 200 yds. wide in places with an area of open water to the south-west. Sounds of pressure were heard along this lead, which soon closed to a width of about 30 yds. and then froze over. The temperature at that time was —23° Fahr.
The most severe blizzard we had experienced in the Weddell Sea swept down upon the Endurance on the evening of the 13th, and by breakfast-time on the following morning the kennels to the windward, or southern side of the ship were buried under 5 ft. of drift. I gave orders that no man should venture beyond the kennels. The ship was invisible at a distance of fifty yards, and it was impossible to preserve one’s sense of direction in the raging wind and suffocating drift. To walk against the gale was out of the question. Face and eyes became snowed up within two minutes, and serious frost-bites would have been the penalty of perseverance. The dogs stayed in their kennels for the most part, the “old stagers” putting out a paw occasionally in order to keep open a breathing-hole. By evening the gale had attained a force of 60 or 70 miles an hour, and the ship was trembling under the attack. But we were snug enough in our quarters aboard until the morning of the 14th, when all hands turned out to shovel the snow from deck and kennels. The wind was still keen and searching, with a temperature of something like —30° Fahr., and it was necessary for us to be on guard against frost-bite. At least 100 tons of snow were piled against the bows and port side, where the weight of the drift had forced the floe downward. The lead ahead had opened out during the night, cracked the pack from north to south and frozen over again, adding 300 yds. to the distance between the ship and “Khyber Pass.” The breakdown gang had completed its work by lunch-time. The gale was then decreasing and the three-days-old moon showed as a red crescent on the northern horizon. The temperature during the blizzard had ranged from —21° to —33.5° Fahr. It is usual for the temperature to rise during a blizzard, and the failure to produce any Föhn effect of this nature suggested an absence of high land for at least 200 miles to the south and south-west. The weather did not clear until the 16th. We saw then that the appearance of the surrounding pack had been altered completely by the blizzard. The “island” floe containing the Endurance still stood fast, but cracks and masses of ice thrown up by pressure could be seen in all directions. An area of open water was visible on the horizon to the north, with a water indication in the northern sky.
The ice-pressure, which was indicated by distant rumblings and the appearance of formidable ridges, was increasingly a cause of anxiety. The areas of disturbance were gradually approaching the ship. During July 21 we could bear the grinding and crashing of the working floes to the south-west and west and could see cracks opening, working, and closing ahead.
“The ice is rafting up to a height of 10 or 15 ft. in places, the opposing floes are moving against one another at the rate of about 200 yds. per hour. The noise resembles the roar of heavy, distant surf. Standing on the stirring ice one can imagine it is disturbed by the breathing and tossing of a mighty giant below.”
Early on the afternoon of the 22nd a 2-ft. crack, running south-west and north-east for a distance of about two miles, approached to within 35 yds. of the port quarter. I had all the sledges brought aboard and set a special watch in case it became necessary to get the dogs off the floe in a hurry. This crack was the result of heavy pressure 300 yds. away on the port bow, where huge blocks of ice were piled up in wild and threatening confusion. The pressure at that point was enormous. Blocks weighing many tons were raised 15 ft. above the level of the floe. I arranged to divide the night watches with Worsley and Wild, and none of us had much rest. The ship was shaken by heavy bumps, and we were on the alert to see that no dogs had fallen into cracks. The morning light showed that our island had been reduced considerably during the night. Our long months of rest and safety seemed to be at an end, and a period of stress had begun.
During the following day I had a store of sledging provisions, oil, matches, and other essentials placed on the upper deck handy to the starboard quarter boat, so as to be in readiness for a sudden emergency. The ice was grinding and working steadily to the southward, and in the evening some large cracks appeared on the port quarter, while a crack alongside opened out to 15 yds. The blizzard seemed to have set the ice in strong movement towards the north, and the south-westerly and west-south-westerly winds that prevailed two days out of three maintained the drift. I hoped that this would continue unchecked, since our chance of getting clear of the pack early in the spring appeared to depend upon our making a good northing. Soundings at this time gave depths of from 186 to 190 fathoms, with a glacial mud bottom. No land was in sight. The light was improving. A great deal of ice-pressure was heard and observed in all directions during the 25th, much of it close to the port quarter of the ship. On the starboard bow huge blocks of ice, weighing many tons and 5 ft. in thickness, were pushed up on the old floe to a height of 15 to 20 ft. The floe that held the Endurance was swung to and fro by the pressure during the day, but came back to the old bearing before midnight.
“The ice for miles around is much looser. There are numerous cracks and short leads to the north-east and south-east. Ridges are being forced up in all directions, and there is a water-sky to the south-east. It would be a relief to be able to make some effort on our own behalf; but we can do nothing until the ice releases our ship. If the floes continue to loosen, we may break out within the next few weeks and resume the fight. In the meantime the pressure continues, and it is hard to foresee the outcome. Just before noon to-day (July 26) the top of the sun appeared by refraction for one minute, seventy-nine days after our last sunset. A few minutes earlier a small patch of the sun had been thrown up on one of the black streaks above the horizon. All hands are cheered by the indication that the end of the winter darkness is near. . . . Clark finds that with returning daylight the diatoms are again appearing. His nets and line are stained a pale yellow, and much of the newly formed ice has also a faint brown or yellow tinge. The diatoms cannot multiply without light, and the ice formed since February can be distinguished in the pressure-ridges by its clear blue colour. The older masses of ice are of a dark earthy brown, dull yellow, or reddish brown.”
The break-up of our floe came suddenly on Sunday, August 1, just one year after the Endurance left the South-West India Docks on the voyage to the Far South. The position was lat. 72° 26´ S., long. 48° 10´ W. The morning brought a moderate south-westerly gale with heavy snow, and at 8 a.m., after some warning movements of the ice, the floe cracked 40 yds. off the starboard bow. Two hours later the floe began to break up all round us under pressure and the ship listed over 10 degrees to starboard. I had the dogs and sledges brought aboard at once and the gangway hoisted. The animals behaved well. They came aboard eagerly as though realizing their danger, and were placed in their quarters on deck without a single fight occurring. The pressure was cracking the floe rapidly, rafting it close to the slip and forcing masses of ice beneath the keel. Presently the Endurance listed heavily to port against the gale, and at the same time was forced ahead, astern, and sideways several times by the grinding floes. She received one
