Recently finished Bruce Chatwin's In Patagonia. Highly recommended.

On Magellan's 1519 - 1522 expedition.

"On the north shore a landing party found a stranded whale and a charnel-place of two hunded corpses raised on stilts. On the southern shore they did not land.
Tierra del Fuego - The Land of Fire. The fires were the campfires of the Fuegian Indians. In one version Magellan saw smoke only and called it Tierra del Humo, the Land of Smoke, but Charles V said there was no smoke without fire and changed the name.
The Fuegians are dead and all the fires snuffed out. Only the flares of oil rigs cast a pall over the night sky."
