AbstractParks Canada and the Geological Survey of Canada conducted a collaborative fi eld project in 2007 and 2008 at the York Factory National Historic Site of Canada to characterize current perma- frost distribution and support the development of management plans. Seven boreholes were drilled and instrumented to document the ground thermal regime. Ground electrical conductivity surveys were also conducted to further characterize permafrost throughout the site. The results indicate that the distribution of permafrost is discontinuous, and where present, it is generally less than 15 m thick and warmer than -1°C. Permafrost is present in areas where vegetation clearing has probably resulted in reduced snow cover. Permafrost is generally absent where re-establishment of willows has promoted deeper snow cover and higher mean annual ground temperatures.
