Ice-covered Antarctica is one of Earth's most hostile natural environments.
But a new find by the Antarctic Heritage Trust suggests it's no match for a 106-year-old British fruitcake.
Conservators found the elderly cake on Cape Adare, and believe it belonged to British explorer Robert Falcon Scott - known as Scott of the Antarctic.
Although the tin was rusted, the team said the cake was in "excellent condition" and smelled edible.
The New Zealand-based trust found it in Antarctica's oldest building, a hut built by Norwegian explorer Carsten Borchgrevink's team in 1899, and used by Capt Scott in 1911 during his Terra Nova expedition.
The polar pioneer was said to be fond of this particular cake, made by the British biscuit company Huntley & Palmers.
