This data set consists of elemental analysis data for selected B horizons from Wounded Moose paleosols sampled by Tarnocai and Smith. The file includes the original ALS lab report, additional panes showing comparison of replicates, and calculation of a weathering index.
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Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr.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:

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.

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).

Data set "Yukon-AK 2004 soils data (Lost Chicken).xls" consists of Pliocene Rego Humic Gleysol (peaty) data from the Lost Chicken Mine site.
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.
Undated 2-page memo to Dave [Carter?] [from Scott Smith?] with review comments on a draft manuscript; attached to a draft table with basic characterization data for 3 paleosol sequences at the Lost Chicken mine (profile numbers 91010, 91011, & 91013)

The Lost Chicken Mine, a placer gold mine in eastern Alaska, approximately 120 km west of Dawson City, Yukon, is an important fossil locality for the late Pliocene (approximately 2.5 – 3.0 million years ago). A comprehensive account of the stratigraphy and paleontology of this site was given by:
Matthews, J.V., Jr., J.A. Westgate, L. Ovenden, L.D. Carter, and T. Fouch. 2003. Stratigraphy, fossils, and age of sediments at the upper pit of the Lost Chicken gold mine: new information on the late Pliocene environment of east central Alaska. Quaternary Research 60: 9-18. https://doi.org/10.1016/S0033-5894(03)00087-5
Dr. Paul Sanborn visited the site on July 20, 2004, as part of a group led by Duane Froese (Professor, University of Alberta). The group concentrated on a single exposure (~ 2 m thick) straddling the Lost Chicken tephra, a volcanic ash bed (2.9 ± 0.4 myr) which is a major stratigraphic marker at the site. Sanborn described, photographed, and sampled this exposure, and obtained a basic set of characterization data. Intact samples were collected but thin sections were never produced.
