This paper describes soils developed on calcareous bedrock with up to 60 cm of humus-rich A horizons from the Ogilvie Mountains in the Yukon Territory. These soils are of interest because they do not fit well into soil classification schemes and results from conventional analytical techniques are unreliable. Some of the unusual characteristics of these soils are: well-developed Ah horizons with high organic carbon contents, and high Ch/Cf ratios, on well-drained sites in a dry permafrost environment. We postulate that these soils are of polygenetic origin. They have developed under conditions where humic acid accumulation is greater than decomposition as a result of the limestone-rich environment, and where a portion of the organic component might be derived from residues of bedrock weathering.
