Fox In The Arctic

The yacht Fox, under the command of Irish explorer Sir Francis Leopold McClintock (1819 - 1907), makes its way through arctic pack ice, circa 1858. McClintock is on his second mission to find the 1845 expedition of Sir John Franklin, which disappeared during a search for the Northwest Passage. The expedition is sponsored by Lady Franklin and by public subscription. (Photo by Hulton Archive/Getty Images)
