During Darwin's lifetime, many geographical features were given his name. An expanse of water adjoining the Beagle Channel was named Darwin Sound by HMS Beagle captain Robert FitzRoy after Darwin's prompt action, along with two or three of the men, saved them from being marooned on a nearby shore when a collapsing glacier caused a large wave that would have swept away their boats, and the nearby Mount Darwin in the Andes was named in celebration of Darwin's 25th birthday. Another Darwin Sound in British Columbia's Queen Charlotte Islands, between Moresby Island and Lyell Island, was named in 1878 by Canada's then-chief geographer George M. Dawson for Darwin. When the Beagle was surveying Australia in 1839, Darwin's friend John Lort Stokes sighted a natural harbour which the ship's captain Wickham named Port Darwin. The settlement of Palmerston founded there in 1869 was officially renamed Darwin in 1911. It became the capital city of Australia's Northern Territory.
