"Berta . . . dug out one more cell just under the ice surface, leaving a nearly transparent sheet of ice like a greenhouse roof; and there, alone, she worked at sculptures. They were beautiful forms, some like a blending of the reclining human figure with the subtle curves and volumes of the Weddell seal, others like the fantastic shapes of ice cornices and ice caves. Perhaps they are there still, under the snow, in the bubble in the Great Barrier."
