–from Shackleton’s account “South”–
“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 stages’ 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.”
