In 1914 Ernest Shackleton and his crew set sail to be the first to cross the Antarctica continent from coast to coast. At 76??34'S pack ice closed around the Endurance in the Weddell Sea preventing the ship from ever approaching the continent. The Endurance was finally crushed almost 300 days later. They abandoned ship, making camp on the pack ice. They hauled their lifeboats until they could put them in water to sail to Elephant Island. Due to the condition of the crew, Shackleton decided that they could not winter on Elephant Island. He and 5 others set out for the closest inhabited island, South Georgia that was 800 miles away. After 4 attempts to save his crew, Shackleton finally made it to Elephant Island on August 30th 1917.
