The long, cold slog

(Michael Becker, a doctoral student at McGill University, was a scientific diver on an expedition to Lake Untersee, Antarctica - this the third of 6 blog posts): There are no helicopters on this end of the continent. For someone as unenthusiastic about walking as I am, this news comes as a definitive blow to my goal of doing as little exercise as possible. But even an ultramarathoner would be chilled by the prospect of an 80-mile journey over treacherous glacial crevasses with several tons of gear. Back in the old days a similar journey might involve days of sledging and potentially eating a few of your dogs.
