On this day 105 years ago, on February 20, 1920 (January 1, 1920 lunar calendar), American polar explorer Robert Perry died. In 1909, American explorer Robert Edwin Peary (1856-1920) claimed that he led a team from Cape Columbia, Canada, and covered a distance of 764 kilometers in 37 days to reach the North Pole. However, in such harsh climate conditions and geographical environment, people have always doubted how Perry and his party could reach the North Pole in 37 days. To verify the American explorer's feat, the British explorer Tom. Avery's five-man expedition set out again from Cape Columbia, Canada, on March 20, 2005, using the same equipment and trekking along Piri's route that year, and reached the North Pole on April 26, a period of 37 days. The same equipment and the same route On March 20, the Buckley Ultimate Arctic Expedition, led by Avery, set out from Cape Columbia, Canada, using the same equipment - Eskimo sled dogs and custom wooden sledges - all the way to the North Pole at 1 noon on April 26. This time they traveled slightly faster than Piri, and they were reported to be 11 kilometers ahead of Piri. The expedition, funded by the Buckley Fund, aimed to prove that the controversial trip to Perry was achievable. "Robert Perry is dead and his record is unproven, so the key thing was to prove that it was achievable," said a spokesman for the expedition. In addition to Avery, the expedition leader, the expedition has four members, one of whom is a female explorer. The four members are: Andrew Gerber of South Africa, Mattie McNair of the United States (female), George. Welsh and Canadian teacher and dog trainer Hugh. Dale Harris. The expedition team began preparations a year before departure. In order to overcome the harsh climate and geographical environment, they practiced the skills of dog sledding in the extremely harsh climate conditions of Baffin Island. During the journey, the expedition team overcame the cold of minus 45 degrees Celsius and conquered the ice floes that caused great trouble. Pioneers experienced three failures. Nearly a century ago, the British government set aside a fund to encourage Arctic exploration, preparing a prize for the first explorer to reach the North Pole. Many explorers are eager to take the crown of being the first to reach the North Pole and win this fascinating historical honor. Robert Perry, an American explorer with a good nature, began his bold plan to try. He has made years of preparations and accumulated a wealth of experience for the expedition to the North Pole. He first trained on the ice of Greenland on foot and on dog sledges, and learned from the failures of previous Arctic expeditions. Perry's Arctic expedition led a total of four expeditions to the North Pole, the first in 1901. The first three failed, but each made small progress and laid the foundation for the final victory. In 1909, Perry led a six-man expedition on five sledges, led by 40 dogs, from Cape Columbia in northwest Greenland, about 760 kilometers from the North Pole. On April 6, the expedition reached the North Pole.
