Abstract
This report presents subsurface temperature measurements recorded to the end of August 1981 in the Yukon Territory. ... Data from 14 shallow boreholes (0-10 m), 28 intermediate depth holes (10-125 m) and 29 deep holes (greater than 125 m) have been compiled and presented as tables of temperature logs at each borehole and as graphs of temperature variation with depth. Maps showing mean ground surface temperatures, mean ground temperature gradients, permafrost occurrences and thickness have been prepared from the data. Mean annual ground surface temperatures approximated by extrapolation from the ground temperature profiles range from -9.7 degrees to 3.8 degrees C. Geothermal gradients, calculated from the data at the deep holes, range from 20 to 42 m/km. A map showing permafrost distribution indicates sites where permafrost was encountered and includes, whenever possible, the permafrost thickness determined from the borehole data. Permafrostoccurs sporadically and at attitudes above 1500 m in the south and continuously with a thickness of up to 200 m in the north.
