AbstractA terrain inventory in the Camsell Bend map area (NTS 95 J), southern Mackenzie River watershed, Northwest Territories, distinguishes among complex landslides involving bedrock and unconsolidated surfi cial deposits, landslides involving bedrock, landslides in surfi cial deposits, and landslides in earth materials containing permafrost. Geoscience data collected include the spatial distribution of surfi -
cial deposits and landforms, and the classifi cation, dimensions, physiographic setting, and age of landslide events. Dominant factors in triggering and velocity of landslides are slope, drainage characteristics, and water content of surfi cial material or bedrock. Other controls include distribution and intensity of wildfi res, local relief, orientation of bedrock structures, debris thickness, and distribution of ground ice, precipitation and vegetation. The outcome of applying knowledge gained through this work is an increased awareness and response to landslide geohazards, risks, and consequences, and improved decisions on regional development of infrastructure by geoscientists, engineers, ecologists, planners, emergency response offi cials, lawyers, and local communities.
