"The main objective of this report is to provide an inventory of current (intact or degrading) and old (completely degraded) lithalsas in a representative study area of the southern North Slave region between Behchoko and Yellowknife in the Northwest Territories. A lithalsa is an ice-rich mound of permafrost that causes the soil to settle downward and water to pond if the ice core thaws (thermokarst pond). Lithalsas, widespread in this region, are therefore very sensitive to thawing"--Abstract, page 1. Permafrost Northwest Territories. Pergélisols Territoires du Nord-Ouest.
