Albert Paddock Crary, was an American pioneer polar geophysicist and glaciologist. He was the first person to have set foot on both the North and South Poles, having made it to the North Pole on May 3, 1952 and then to the South Pole on February 12, 1961, as the leader of a team of eight. The South Pole expedition set out from McMurdo Station on December 10, 1960, using three Snowcats with trailers. Crary was the seventh expedition leader to arrive at the South Pole by surface transportation. He was widely admired for his intellect, wit, skills and as a great administrator for polar research expeditions.

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.
