pass connecting two glacial valleys running from North to South between the heads of Sands Fjord to the north and Frigg Fjord to the south. Its easternmost subranges almost reach the eastern end of northern Peary Land. The area near the Lincoln Sea coast, southwest of Cape Morris Jesup is known as Ulvebakkerne (Wolf Hills). Peaks Apart from its highest point Helvetia Tinde, not many peaks of the Roosevelt Range have been named. Other relevant mountains in the range are Paradisfjeld and Mary Peary Peaks (Mary Peary Tinder), located east of the Polar Corridor in a roughly central position, as well as Birgit Koch Peaks (Birgit Koch Tinder) and Rink Mountain (Rink Bjerg), a little further to the east. Subranges The H. H. Benedict Range (H. H. Benedict Bjerge), highest point Stjernebannertinde, and the Daly Range (Daly Bjerge), both located at the eastern end in Johannes V. Jensen Land, are subranges of the Roosevelt Range. Glaciers The valleys between mountains are filled with glaciers or icefields, none of which are very large. In the same manner as other features in this range many glaciers are unnamed. Thomas Glacier (Greenland) Raven Glacier A.

It is part of the belt Caledonian folding that extends eastward from north Ellesmere Island. The ages of rocks in the range area are from Precambrian to Upper Silurian, with low-grade marbles, psammites, sandstone, shales, quartzite and mudstones. Bibliography H.P.
