in 1997 ]] The Arctic Cordillera is a mountainous region in and Mount Thor . GEOGRAPHY The Arctic Cordillera was uplifted in the middle of the Mesozoic Era when the North American Plate moved northward. The Arctic Cordillera contains Igneous and Metamorphic Rocks , but for the most part is composed of Sedimentary Rock . The Arctic Cordillera is younger than the Appalachians , and so erosion has not had time to reduce it to rounded Hill s. The mountains are also barren because Tree s can neither survive the extremely cold winter temperatures, nor grow during the short Summer s. Vast areas are covered by permanent ice and snow. The Arctic Cordillera resembles the Appalachians in composition and contain similar types of Mineral s. The mineral resources have not been greatly exploited, however, because the region's remote location makes development too costly when cheaper alternatives exist further south. The Arctic Cordillera is one of Canada's most inhospitable climates. During the Winter , the temperature is nearly -35°C and it is very dark and long. Only about 1,000 people live in the region, and most of the people who live in the region survive by Hunting , Fishing , and Trapping . SUB-RANGES NATIONAL PARKS |
