1'. S. Navy, Official White Tongues Lick Out from Dark Mountains and One Hangs Suspended in Air THIS small, unnamed glacier, its milky whiteness contrasting with the black peak in the fore ground, is one of a series flowing down parallel valleys from the west coast mountains. A few miles away is a similar narrow valley which is entirely free of ice. The glacier which once flowed through it has retreated, leaving only bare rocks. Why this should have occurred in one valley only is unexplained. Note the tongue of white hanging over the black wall of the valley on the left, like a waterfall sud denly frozen in space. This is a typical icefall, of which hundreds were found in the area. The glacier flows into the Ross Sea just west of Mount Erebus, which is visible in the background (page 476). Beaufort Island appears as a patch of white like a small iceberg on the skyline.
