4. Trapped in the Ice
In January 1915, the Endurance became trapped in the dense pack ice of the Weddell Sea, halting the crew’s progress and confining them to the ship. The surrounding ice exerts immense pressure, causing the ship to twist and contort as the ice floes shifted. This relentless force eventually led to the ship’s sinking in November 1915. The dangers of Antarctic pack ice are profound, as it can crush and sink vessels, posing significant risks to modern ice-travelers. (smithsonianmag.com)
