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.

This work built on a pioneering study from the previous decade:
Foscolos, A.E., N.W. Rutter, and O.L. Hughes. 1977. The use of pedological studies in interpreting the Quaternary history of central Yukon Territory. Bulletin 271. Geological Survey of Canada, Ottawa. 48 p. https://doi.org/10.4095/103066

Tarnocai and Smith presented their results in two publications:
C. A. S. Smith, C. Tarnocai, and O. L. Hughes. 1986. Pedological investigations of Pleistocene glacial drift surfaces in the central Yukon. Géographie physique et Quaternaire, 40 (1): 29–37. https://doi.org/10.7202/032620ar
Tarnocai, C. and C. A. S. Smith. 1989. Micromorphology and development of some central Yukon paleosols, Canada. Geoderma 45 (2): 145-162. https://doi.org/10.1016/0016-7061(89)90047-5

Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr.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

Attached description: The thriving city of Prince Rupert is shown in this aerial picture. Prince Rupert has been enjoying a construction boom which includes the construction of the $80 million Skeena Kraft mill, hundreds of single-family homes, and hundreds of units in apartments, motels, and hotels. The construction of Skeena Kraft provided the stimulus for a population expansion to over 17,000. The Columbia Cellulose and Skeen a Kraft payrolls account for well over a third of the incomes of the city. Prince Rupert is, along with Terrace, the hub of a new economic region encompassing the Nass and Skeena valley regions.
