The eastern flank of the Mackenzie Mountains has a complex history of multiple glaciations by both the Laurentide and Cordilleran ice sheets, recorded in thick sequences of glacial sediments that were documented at 3 locations (Katherine Creek, Little Bear River, Inlin Brook) by:
Duk-Rodkin, A., R.W. Barendregt, C. Tarnocai, and F.M. Phillips. 1996. Late Tertiary to late Quaternary record in the Mackenzie Mountains, Northwest Territories, Canada: stratigraphy, paleosols, paleomagnetism, and chlorine-36. Canadian Journal of Earth Sciences 33 (6): 875-895. https://doi.org/10.1139/e96-066
Of the 3 sites, the exposure on Inlin Brook, a tributary of the Keele River, was the least well-documented, so in summer 2004 Dr. Paul Sanborn joined a field party of the Geological Survey of Canada (GSC) based at Tulita, NWT, and was given helicopter support to visit Inlin Brook (August 5-8). A brief visit was also made to the Little Bear River site.
On August 9-10, Sanborn joined Alejandra Duk-Rodkin (GSC) and Rene Barendregt (U Lethbridge) in helicopter-assisted field work at sites in the Franklin Mountains and elsewhere east of the Mackenzie River.

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Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr.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

"Mineralogy of clay and sand fractions of soils developed from till, glaciofluvial and glaciolacustrine deposits in central interior British Columbia" was a preliminary internal report that provides some background to Arocena and Sanborn's regional soil mineralogy study, as well as a compilation of the mineralogical data.
The key results from this work were later published as:
J.M. Arocena and P. Sanborn. 1999. Mineralogy and genesis of selected soils and their implications for forest management in central and northeastern British Columbia. Canadian Journal of Soil Science 79: 571-592. https://doi.org/10.4141/S98-07
This Ministry of Forests internal memorandum of 30 June 1997 from Paul Sanborn to Regional & Research Branch soil scientists provides comparison of Morgan's extractant and BaCl₂ for cations, using the 57 samples from the regional soil mineralogy study.
