Episode 02: Endurance and the Patience of Cold
1916. Elephant Island. Antarctica. Twenty-two men live beneath two upturned lifeboats on a narrow strip of beach, the sea on one side and a vertical wall of rock and glacier on the other. Their clothes are damp. The only light comes from burning seal blubber. Their faces are permanently black from the smoke. Six of their crewmates left weeks ago in an open boat to fetch help from a whaling station eight hundred miles away. There is no way to know if they made it.
This episode is about the four months those twenty-two men waited, and what it took to keep each other alive. About Shackleton and the five men in the James Caird, sailing through the Drake Passage in winter. About the mountain crossing on South Georgia that ended in a controlled slide down a glacier. And about a different kind of moonshot — the one where the original mission has died and the only remaining job is to bring everyone home.
The book is Endurance: Shackleton's Incredible Voyage by Alfred Lansing (1959). Two hundred and eighty pages. Lansing interviewed the surviving men in their seventies, and the book is built from that primary material. Not a word too much.
Episode two of Contact Light: The Bookshelf. Travels in the country of ambition, between idea and reality. Hosted by Mark Zwinderman.
