During Darwin's lifetime, many geographical features were given his name. An expanse of water adjoining the [[Beagle Channel]] was named [[Darwin Sound]] by [[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 (Andes)|Mount Darwin]] in the Andes was named in celebration of Darwin's 25th birthday. When the [[HMS Beagle|Beagle]] was surveying Australia in 1839, Darwin's friend [[John Lort Stokes]] sighted a natural harbour which the ship's captain [[John Clements Wickham|Wickham]] named [[Port Darwin]]: a nearby settlement was renamed [[Darwin, Northern Territory|Darwin]] in 1911, and it became the capital city of Australia's [[Northern Territory]].
