There are no trees in the Torngat Mountains because the mountains lie in an arctic tundra climate and are therefore above the tree line. Permafrost is continuous on the Quebec side of the border, and it is extensive but discontinuous on the eastern Atlantic side. The terrain is over 300 m (984 ft) above sea level and is predominantly rocky desert.
This is a hilly area that lies between the boggier Arctic coastal tundra to the north and the Brooks Range to the south, and stretching from the Chukchi Sea east across northern Alaska to the border with Canada's Yukon Territory. The Noatak River valley is the only forested area. [2]

According to the US Energy Information Administration, the arctic tundra holds an estimated 13% or 90 billion barrels of the world's undiscovered conventional oil sources. However, there are a number of challenges to oil exploration, drilling, and transportation in an arctic tundra environment that limits the profitability of the venture. [15]
Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
