Tarnocai and Smith recorded their site locations on NTS topographical maps, and provided a set of scans of these maps.

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Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr.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

This file consists of photocopies of 76 detailed soil description forms from the 1983 Yukon Paleosol Study by Tarnocai and Smith.

Original Land Resource Research Institute soil description detail forms prepared by Scott Smith for 3 locations, annotated on covers as follows:
SS91010 Lost Chicken Regosol Paleosol 26/6/91
SS91011 Lost Chicken Ash in Felty Peat 27/6/91
SS91013 Lost Chicken Mine “Up the Creek” ash site 28/6/91

Each of the three forms contains an attached annotated Polaroid photograph depicting each site.

File consists of photographic slides from the Arocena & Sanborn 1999 regional soil mineralogy study.
