| Abstract | Investigations of alpine permafrost in the Western Cordillera of Canada were initiated in 1974 on Plateau Mountain located in the front ranges of the Rocky Mountains 80 km southwest of Calgary, Alberta. Thermocouple and thermistor cables to measure ground temperatures were installed in boreholes to depths of 15 to 30 m on the summit above treeline at 2519 m elevation and down the forested mountain side to 2103 m elevation. Monthly observations on these cables and temperature checks in an ice cave confirm the existence of permafrost (-1.0 to -1.5 degrees C). The mean annual air temperature at the summit is -4.1 degrees C and strong winds remove most of the snow. Temperature measurements indicate that permafrost extends to a depth of possibly 100 m or more, the upper portion having adjusted to the present climate and the lower layers being relic. |
