Roosevelt Range

The Roosevelt Range or Roosevelt Mountains (Danish: Roosevelt Fjelde) is a mountain range in Northern Greenland. Administratively this range is part of the Northeast Greenland National Park. Its highest peak is the highest point in Peary Land.

Located about 720 kilometres (450 mi) from the North Pole, the Roosevelt Range is the northernmost mountain range on Earth.

The mountain chain was named by Robert Peary after U.S. President Theodore Roosevelt, who would become one of the main backers of Peary's 1905 Arctic expedition.

During the first half of the 20th century the range was quite unexplored, except for the mapping from the coast in 1907 of the Daly Range by Johan Peter Koch, Aage Bertelsen and Tobias Gabrielsen, the northern team of the ill-fated Denmark expedition, as well as aerial surveys and mapping begun by Lauge Koch in the 1920s.

In 1953 a geological expedition crossed the range through the Polkorridoren pass from Frigg Fjord to Sands Fjord.

The highest peak, Helvetia Tinde was first climbed in 1969 by the members of an expedition of the British Joint Services during a topographic and geological survey of the northern part of Peary Land. The second ascent of the summit was made in 1996. Later expeditions also went to the northern foothills of the range, not far from Cape Morris Jesup, and sought to identify and climb the "northernmost mountain on earth".

The Roosevelt Range is an up to 1,929 m (6,329 ft) high mountain range in Northern Peary Land, formed by alpine-type mountains. The topography of the mountains is deeply eroded, with sharp, jagged ridges and precipitous cliffs. The area of the range is uninhabited.

Owing to a structural continuum in the mountains between Johannes V. Jensen Land in the east and Nansen Land in the west, American geologist William E. Davies called the wider range the "Nansen-Jensen Alps" in a work he published in 1972. The Roosevelt Range would be thus a subrange of a wider mountain chain with its westernmost foothills in Nansen Land, reaching all the way to Johannes V. Jensen Land in the east.
