Contents

This report provides the methodology and results of identification and mapping of lithalsas, degraded lithalsas, and thermokarst from high resolution satellite imagery. We present an inventory of 475 intact lithalsas and 556 completely degraded lithalsas in the North Slave region. We also updated the elevation data for thermokarst features in the study area. The inventories and databases are prepared for assessment of the relations between elevation, surface geology and distribution of lithalsas, and the trajectory of thermokarst development in the region. The inventories included with this report can be used directly in a Geographic Information System (GIS)
