Alert, Nunavut, Canada on the northern tip of Ellesmere Island is the northernmost inhabited community on earth. The North Pole is only 508 miles away.
The community was named after the HMS Alert, the first ship to reach the north end of Ellesmere Island in 1875. Originally an Inuit community, Alert now houses Canadian Forces Station Alert, a weather station, a Global Atmosphere Watch laboratory, and an airport. There are also five permanent residents.
