Matienzo was an Argentine research base on a small island 30
miles off the coast of the Antarctic Peninsula. It was surrounded by a vast
plain of white—a slab of glacial ice, 700 feet (215 meters) thick, that floated
on the ocean. That floating slab, called Larsen A Ice Shelf, covered an area of
water the size of San Francisco Bay. It had existed for a thousand years or
more. But this hot summer it looked strange. The men had to go onto the ice
shelf to collect snow for drinking water, and it made them uneasy.
The ice shelf was crisscrossed with narrow cracks—which the
men nervously jumped over—and dotted with deep blue melt ponds. It was there,
protruding from a melt pond, that they found the sled. It must have been
discarded by a British expedition that passed through decades before.
That old sled turned out to be an omen of disaster, like a
long-buried coffin that resurfaces when a city is ravaged by floods. It showed
that Larsen A had been quietly deteriorating for years.
