A century ago today, Sir Ernest Shackleton and the crew of the 'Endurance' were camping on the ice after the sinking of his ship - crushed in the ice. They faced possibly the most incredible story ever told, as they proceeded to save the life of everyone involved, with a number of voyages including one in the James Caird to South Georgia.
Parts of the journey were documented by the expedition's photographer Frank Hurley, who managed to save just some of the images that he took.
An exhibition opens today at the Royal Geographical Society, which shows the images, which have been digitised directly from the original glass plates. It runs through to the end of February 2016. I shall be taking this in at some point when I next go to London.
See details about the exhibition, which is free to enter, and an online exhibition on the RGS website here.
You can see a few sample images on this BBC news article about the exhibition.
The RGS has also produced some resources linked to their collections.
And finally, check out William Grill's wonderful picture book of 'Shackleton's Journey' and the associated Activity Book which we have used to produce some interesting resources.
