The Long, Long Night
A new berg that was going to give us some cause for anxiety made its appearance on the 14th. It was a big berg, and we noticed as it lay on the north-west horizon that it had a hummocky, crevassed appearance at the east end. During the day this berg increased its apparent altitude and changed its bearing slightly. Evidently it was aground and was holding its position against the drifting pack. A sounding at 11 a.m. gave 197 fathoms, with a hard stony or rocky bottom. During the next twenty-four hours the Endurance moved steadily towards the crevassed berg, which doubled its altitude in that time. We could see from the mast-head that the pack was piling and rafting against the mass of ice, and it was easy to imagine what would be the fate of the ship if she entered the area of disturbance. She would be crushed like an egg-shell amid the shattering masses.
Worsley was in the crow’s-nest on the evening of the 15th, watching for signs of land to the westward, and he reported an interesting phenomenon. The sun set amid a glow of prismatic colours on a line of clouds just above the horizon. A minute later Worsley saw a golden glow, which expanded as he watched it, and presently the sun appeared again and rose a semi-diameter clear above the western horizon. He hailed Crean, who from a position on the floe 90 ft. below the crow’s-nest also saw the re-born sun. A quarter of an hour later from the deck Worsley saw the sun set a second time. This strange phenomenon was due to mirage or refraction. We attributed it to an ice-crack to the westward, where the band of open water had heated a stratum of air.
The drift of the pack was not constant, and during the succeeding days the crevassed berg alternately advanced and receded as the Endurance moved with the floe. On Sunday, April 18, it was only seven miles distant from the ship.
“It is a large berg, about three-quarters of a mile long on the side presented to us and probably well over 200 ft. high. It is heavily crevassed, as though it once formed the serac portion of a glacier. Two specially wide and deep chasms across it from south-east to north-west give it the appearance of having broken its back on the shoal-ground. Huge masses of pressure-ice are piled against its cliffs to a height of about 60 ft., showing the stupendous force that is being brought to bear upon it by the drifting pack. The berg must be very firmly aground. We swing the arrow on the current-meter frequently and watch with keen attention to see where it will come to rest. Will it point straight for the berg, showing that our drift is in that direction? It swings slowly round. It points to the north-east end of the berg, then shifts slowly to the centre and seems to stop; but it moves again and swings 20 degrees clear of our enemy to the south-west.... We notice that two familiar bergs, the Rampart Berg and the Peak Berg, have moved away from the ship. Probably they also have grounded or dragged on the shoal.”
