“On these fine, clear, sunny days wonderful mirage effects could be observed, just as occur over the desert. Huge bergs were apparently resting on nothing, with a distinct gap between their bases and the horizon; others were curiously distorted into all sorts of weird and fantastic shapes, appearing to be many times their proper height. Added to this, the pure glistening white of the snow and ice made a picture which it is impossible adequately to describe.”

— Ernest Shackleton, South
