1909 American explorer Robert Edwin Peary is generally credited with having led the first expedition to reach the North Pole - at the age of 53. With temperatures falling to -50C, Peary writes: "The bitter wind burned our faces so that they cracked. The air was as keen and bitter as frozen steel." On his return he learns that his rival, Frederick Cook, is claiming to have reached the pole a year earlier. After an investigation, Congress rules in favour of Peary.

The Arctic ice-pack is moved by ocean currents, as proved by George De Long when his ship Jeanette drifted 310 miles in 21 months in 1880/81.

The Aurora Borealis, or Northern Lights, are caused by electrical solar discharges in the upper atmosphere and are visible at some time on every clear dark night within 20 degrees of the magnetic pole.

With other continents explored, the North Pole was alluded to by writers such as Mary Shelley as the site of the Garden of Eden.
