There is no land at the North Pole, only water and ice that floats and moves. It's always a dangerous place, but winter is the worst time of the year. The sun doesn't come up for three months, and the temperature can be-400F 40°C. But Boerge grew up in Norway, and he loved skiing and climbing mountains. Mike Horn was a champion athlete from South Africa. They were ready for the challenge. The two explorers wanted to set out right away, but the ice was moving too fast. They were waiting in their tent when Boerge heard a strange noise. Mike, isthat you?" Boerge asked. Suddenly, the tent ripped open. It was a polar bear! While they were looking for their guns, the bear grabbed some of their food. They didn't sleep very well that night.
