Baffin Island, Nunavut - According to Downhomer Magazine, the largest iceberg in the Northern Hemisphere was spotted near Baffin Island in 1882. It was 13 km (8mi) long, 6 km (3.7 mi) wide, 20metres (65 ft) high, and would have weighed more than 9 billion tonnes. Icebergs of the north Atlantic are created from frozen fresh water that has calved off off glaciers. Each one starts as snow that has fallen thousands of years ago, and over time the snow compacts into a solid frozen mass and is pushed in to the ocean by ice that is created later. It's estimated that there would have been so much fresh water in an iceberg this size, it could have produced enough water for everyone in the world to drink a liter a day for four years.
