Further European contact with Napuka Atoll only took place again two centuries later, in 1765, with British explorer John Byron. He named Napuka and Tepoto "Disappointment Islands" because he found the natives to be hostile toward him. The islands were also visited by the United States Exploring Expedition in 1839. No one can LIVE there. No one can stay forever on this island because it lacks fresh water. There's no life source flowing from the beautiful outcrop of rock in the middle of the ocean. ... If anyone decided to live on Disappointment Island they could only stay as long as their water supply continued.
