South Georgia island was where Ernest Shackleton finally ended up.
He landed on the wrong side and had to scale a mountain range to get to the only inhabited spot, a whaling station. I saw this documentary recently on a research expedition to locate his ship, The Endurance in the Waddell sea.
800 miles in a little open boat from Elephant island/south Shetland islands through the roughest seas on this planet. And then he and his small crew had to climb over a mountain range. Conrad Anker, narrated. He's a multiple time Everest summiter. He traced the route. He was blown away by the technical nature, the limited resources they would have had
Shackleton made it. Then went back to Elephant island and rescued the rest of his crew.
The Waddell sea off of Anarctica is pretty much just a giant floating iceberg. Endurance spent 11 months trapped in pack ice there and drifted almost 300 miles before it was cruched like kindling and had to be abandoned.
