Abstract: Procedures are available in the literature for estimating subsurface thermal characteristics of foundation soils in cold regions using published climatic characteristics for a given area. However, the actual subsurface thermal regime can be affected by several factors in addition to the general climatic characteristics of the region. Such factors as vegetation, topography, soil properties, snow cover and drainage can have an effect on the local temperature (micro-climate) which in turn can influence the subsurface thermal regime. This paper presents actual temperature data obtained from thermistor strings monitored over several years within Cominco Alaska's Red Dog Project area in Northwestern Alaska. An interpretation of the data is also provided.
