Ground thermal data generated from an enhanced monitoring network have been summarized for the Mackenzie Valley corridor, Northwest Territories. The snapshot developed for 2007-09 provided a baseline against which future change in ground thermal conditions could be measured as well as providing essential information to support land use planning decisions in the region. Comparison of ground temperatures measured during 2012-14 to this baseline indicates some recent warming of permafrost has occurred with greater changes in ground temperature within colder permafrost in the northern portion of the corridor.
