Edmund Hillary and the Three Poles Challenge

We all know of Sir Edmund Hillary of New Zealand as one of the first two to climb the world’s highest summit, Mt Everest. He also had another feather on his cap: He was the first person to have reached the three extremes – Mt Everest, the North Pole and the South Pole. Thus, the Three Poles Challenge was born.

What is glacial ice?

Glaciers are formed at the North and South Poles and in high mountains, such as the Himalayas. Glaciers are sometimes known as rivers of snow. The snow remains for more than a year and as more snow falls, the lower layers get compressed, forming ice. This ice is called glacial ice. Glacial ice can be more than 1,50,000 years old. About 70 per cent of the world’s fresh water is stored as glacial ice.
