Sailing Antarctica’s Iceberg Alley

One hundred feet tall, two hundred beneath the sea, the massive “cubes” that are the remnants of a massive ice shelf-turned-berg called B15 bob along the Antarctic Sound. Once 160 miles long and 40 wide, the berg has diminished over 14 years courtesy of wind and water. Remaining still are these bobbing cubes and a single impressive stretch measuring more than 10 miles long. Soon it will be even smaller yet, pierced by blue crevasses and scarred by the ravages of cold and current. How this slice has even worked its way into this narrow stretch of Iceberg Alley is a mystery. Says the captain, “It’s like trying to wallpaper your apartment through a keyhole.”
