Study says 'bottom-up' permafrost thaw led to two major N.W.T. landslides

New research investigates two massive landslides in the Sahtu and Dehcho regions of the N.W.T. that happened nearly a decade ago. Researchers found the landslides were caused by permafrost thaw deep in the ground, as opposed to closer to the surface, events put in motion by wildfires that burned decades before.
