A crate of whisky that lay frozen and undiscovered for more than 100 years beneath the hut of Antarctic explorer Sir Ernest Shackleton is being thawed to reveal its secrets.

The crate, left by Shackleton during his 1908 British Antarctic Nimrod Expedition and found this year, was brought back to the Canterbury Museum in Christchurch, where officials said it would be analysed.
