South! The Story of Shackleton's Last Expedition, 1914-1917

"[...]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[...]".
