Myriad Mouths of a Nameless Glacier Yawn to Swallow the Unwary W HAT appear to be ridges are enormous cre vasses, many of them more than 100 feet wide. Some would hardly be apparent to an observer on the ground, since they would be covered with snow bridges. An experienced explorer, however, would note parallel ridges, which would warn him of his peril. Such an area is impassable, even for dog teams or men on foot. Badly crevassed regions like this were heartbreaking to earlier explorers, such as Shackleton and Scott, who crept like ants across the trackless white. Admiral Byrd's trail parties, too, had to find a way around them. This danger area is in an unnamed glacier which originates on the slopes of Mount McClintock, on the western shore of the Ross Shelf Ice. The glacier enters the shelf beyond the black rocks at the top of the photograph.
