Colour-coded map dividing Northwestern British Columbia, the Western Northwest Territories, and the Yukon physiographically.

Map depicts the Gulf of Alaska, Pacific Ocean, Chicagof Island, Baranof Island, Alaskan Boarder, Yukon Territory Boarder, Telegraph Creek, Dease Lake and "Mount Brook" along the Graham Inlet.

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Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr.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 file consists of photocopies of 76 detailed soil description forms from the 1983 Yukon Paleosol Study by Tarnocai and Smith.

This file consists of photocopies of lab data sheets for Tarnocai & Smith Yukon soil samples from the Land Resource Research Institute, Agriculture Canada.

These lab data sheets were transcribed into an Excel spreadsheet (see item 2023.2.2.6.3).

  Soil 2
• 90% Ahk material, 2-10 cm thick
• Ahk – 10YR 3/2 d
• Bmk – 7.5YR 4/2 d
• less abundant carbonate than in paleosols & loess below
  Soil 3 - most of exposure has Ahk (2-5 cm thick) over Bmk (4-10 cm thick), with carbonates as for Soil 5
  Soil 4 - mostly Ahk (10YR 3/2 d) material 2-8 cm thick, some Bmk (10YR 4/2 d) < 2 cm thick, with carbonates as for Soil 5
  Soil 5
• complex intermixing of Ahk & Bmk material, charcoal most abundant in Ahk
• individual colour bands 2-10 cm thick
