“Night was upon us, and for an hour we plodded along in almost complete darkness, watching warily for signs of crevasses. Then about 8 p.m. a glow which we had seen behind the jagged peaks resolved itself into the full moon, which rose ahead of us and made a silver pathway for our feet. Along that pathway in the wake of the moon we advanced in safety, with the shadows cast by the edges of crevasses showing black on either side of us. Onwards and upwards through soft snow we marched, resting now and then on hard patches which had revealed themselves by glittering ahead of us in the white light.”

— Ernest Shackleton, South
