These massive icebergs were calved from Greenland's Jakobshavn Glacier, a massive frozen river that sends 11 cubic miles (45 cubic kilometers) of ice into the ocean each year, more than any other glacier in the Northern Hemisphere. "Jakobshavn is the biggest of the big," says photographer James Balog, founder of the Extreme Ice Survey. Balog and his research partners encountered faulty electronics, heavy equipment, and foul weather when they installed 26 solar-powered, time-lapse cameras at 16 glaciers in five countries. The few that Balog has revisited are operating well. "So far, so good," he says.
