Umberto Cagni was a polar explorer and an admiral in the Royal Italian Navy. He is best known for his leadership in a probe, by dogsled, northward over the surface of the Arctic Ocean in 1900. While his party failed in their goal of reaching the North Pole, on 25 April 1900 Cagni and his men achieved the northernmost point achieved by exploration up to that time, 86° 34′ N.

The North Pole, also known as the Geographic North Pole, Terrestrial North Pole or 90th Parallel North, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole.

This pressure ridge at the North Pole is about 1 km long, formed between two ice floes of multi-year ice.
