It has never really crossed my mind to consider how old the iceberg Titanic hit. Possibly as part of an intellectual exercise and a desire to alleviate boredom, scientists at Sheffield University crosschecked data on ocean currents and witness descriptions from 1912. And now they believe it was snow that formed glaciers 100,000 years ago in southwest Greenland that ended up being the infamous iceberg that collided with Titanic in 1912. And it originally was 100ft above the water and possibly 1,700ft long when first formed. By the time it hit Titanic it had shrunk a bit in size but still quite large.
