The Innuitian Mountains consist of numerous smaller mountain ranges. Some of these are the British Empire Range, the Princess Margaret Range and the United States Range, which is the world's second most northerly mountain range after the Challenger Mountains.
The Innuitian Mountains were first seen by European explorers in 1882 by the explorer Adolphus Greely from Lake Hazen.
Geology
The Innuitian Mountains' present form was shaped during the Innuitian orogeny in the middle of the Mesozoic Era when the North American Plate moved northward. The Innuitian Mountains contain igneous and metamorphic rocks, but for the most part are composed of sedimentary rock. They are younger than the Appalachians, so erosion has not yet rounded them significantly.
The Innuitian Mountains resemble the Appalachian Mountains in composition and contain similar types of minerals. The mineral resources have not been greatly exploited, due to the cost of developing such a remote region while cheaper alternatives are available elsewhere. The amount of resources in the Arctic Region is estimated to have 13% of all the world's oil and 30% of the world's gas reserves.
