The landscape is dominated by massive polar ice fields, alpine glaciers, inland fjords, and large bordering bodies of water, distinctive of many similar arctic regions in the world. Although the terrain is infamous for its unforgiving conditions, humans maintained an established population of 1000 people – 80% of whom were Inuit. In addition, the landscape is 75% covered by ice or exposed bedrock, with a continuous permafrost that persists throughout the year, making plant and animal life somewhat scarce. The temperature of the Arctic Cordillera ranges from 6 °C in summer down to −16 °C in winter. Vegetation is largely absent in this area due to permanent ice and snow.
