During the 1980s, Agriculture Canada pedologists Scott Smith (retired from Summerland Research Station, formerly based in Whitehorse) and Charles Tarnocai (retired from Central Experimental Farm, Ottawa) had a large field program which addressed the trends in soil development in the central Yukon. Across this region, particularly between Whitehorse and Dawson City, the land surfaces and surficial deposits vary greatly in age due to the differing extents of glaciations over the past ~2 million years.

Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr. Paul Sanborn, and this resulted in a student project published as:
Daviel, E., P. Sanborn, C. Tarnocai, and C.A.A. Smith. 2011. Clay mineralogy and chemical properties of argillic horizons in central Yukon paleosols. Canadian Journal of Soil Science 91: 83-93. https://doi.org/10.4141/cjss10067

This data set consists of transcribed data from lab data sheets, showing McQuesten-Dawson City paleosol data from the Tarnocai and Smith 1983 AAFC Yukon Paleosol Study. The data set includes chemical and particle size data for Tarnocai & Smith samples, as determined by the Ag Canada lab. Note that the “Site” column indicates the NTS topographic map sheet (e.g. 115P/13) for the sampling locations.
