©Byrd Antarctic Expedition THIS JAGGED CLIFF OF SHELF ICE FORMING THE WEST CAPE OF THE BAY OF WHALESISTHOUGHT TO BE AGROUND A preliminary study of the ice soundings made in the vicinity of the cape, at the junction of the cliff cutting across the center ofthe picture and the water, indicates that the ice rests on submerged mountain peaks rising from the ocean's floor (see illustrations, pages 404, 442, and 443). Each winter, where the Ross Shelf Ice touches the sea, the water freezes against it, forming thinner ice (foreground). When warm weather comes, this ice, already cracked inseveral places, breaks outand floats tosea in mammoth flat chunks. Later in the season all of the ice in the foreground cleared out, leaving West Cape as a peninsula.
