14. The Iceberg
The iceberg was 100 feet tall and came from Greenland. More interesting is the fact that the journey that it made from Greenland was very unlikely. It likely started life somewhere around 1,000 B.C. and after snowfall built up it would compact to become firn. Decades later it would become ice due to the weight of the snow that would top it. It would take centuries for the iceberg to break free and start its journey to infamy. After leaving the Greenland coast it probably went from Baffin Bay to Davis Strait, then to the Labrador Sea and finally the Atlantic.
Here is the crazy part of the whole story of the iceberg, though, of the 15-30,000 that break from Greenland each year, it is estimated that only about 1% ever make it to the Atlantic. Upon being hit, the iceberg would have lasted maybe another year at most before becoming just another freshwater addition to the Atlantic.
