soils . Soils were classified according to the System of Soil Classification for Canada (1970) . The classification of perennially frozen cryoturbed soils was difficult because these soils are not adequately accommodated in the present Canadian classification system . The above system was, however, adapted to classify these cryoturbed soils using an asterisk (*) to indicate that,while they deviate greatly from the name assigned to them, they do have the basic characteristics of this group of soils .
3 . LITERATURE REVIEW Leahey (1947) studied some of the soils along the Mackenzie River and provided a brief analysis and description of soil samples from several locations along the route . Wright et al (1959) discussed the chemical, morphological and mineralogical characteristics of soils developed on alluvial deposits near the mouth of the Hay River, N .W .T . Day (1962) and Day and Rice (1964) provided some information concerning the characteristics of perennially frozen soils occurring along the Mackenzie River . Jeffrey (1964) provided valuable soil information relating to vegetation types occurring along the lower Liard River . A reconnaissance soil survey was carried out by Day (1966, 1968) along the Upper Mackenzie River and the Liard River Valley . These two reports provided detailed descriptions of soils and a soil map of an approximately 6,540,700 acre area along these two rivers . In the summer of 1971 Lavkulich (1971) carried out soil, vegetation and landform studies in the Fort Simpson area in cooperation with Dr . J .S . Rowe of the University of Saskatchewan, Dr . D .S . Lacate of the University of British Columbia and Dr . N .W . Rutter of the Geological Survey of Canada . Some soil information was provided by Janz (1971) for the eastern part of the Mackenzie Delta along with a vegetation study on selected sites . For the interpretation of organic soils the work of Zoltai and Tarnocai (1971) and Tarnocai (1970, 1972) was used . For the interpretation of cryoturbed subarctic and arctic soils, Mackay's work (1958) and papers published in the book "Soils of Eastern Siberia" edited by E .N . Ivanova, were found to be most useful .
