Across the vast landscape of the Northwest Territories (NWT), cold climates and permafrost have preserved large amounts of ancient ground ice for thousands of years. However, recent climate warming is beginning to dramatically alter some of these landscapes. The Northwest Territories Geological Survey (NTGS) is taking a proactive approach to learning more.
A recently-published study in the high-profile journal Geology, titled Climate-driven thaw of permafrost preserved glacial landscapes, northwestern Canada, describes some of the research efforts and findings. Steve Kokelj, a Permafrost...

Permafrost Thaw Causes Lake Drainage and Flow of Debris, Peel Plateau, Northwest Territories, Canada
Permafrost thaw in the northwestern Northwest Territories has caused development of very large thaw slumps. Individual thaw slump disturbances can impact over 30 ha of terrain, displace millions of cubic metres of sediments to reconfigure slopes and impact downstream environments. One particular thaw slump about 20 km northwest of Fort McPherson has been growing for about a decade. It has caused gradual hillside collapse, resulting in the rapid, partial...Pages
