Members of the expedition, including Matthew Henson (left), four local Inuits, and another man, possibly Peary, stand in front of their temporary structure at Cape d'Urville, Ellesmere Island. From 1891 to 1902, Henson and Peary trekked over 9,000 (14,500 kilometers) miles on dogsleds in seven years of expeditions through northern Greenland and Ellesmere Island.
