For July 1-7, 2009, Dr. Paul Sanborn did the first soils field research at the Fort Selkirk volcanic field in central Yukon, with helicopter support and funding from the Yukon Geological Survey.

Initial findings were published in the 2009 edition of Yukon Exploration and Geology, but this paper did not include most of the laboratory data:

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.

For this Northern Rockies pedological study, Dr. Paul Sanborn conducted field work jointly with researchers from the Ministry of Forests and Agriculture Canada from August 21-24, 2012, at two clusters of sites along the Alaska Highway west of Fort Nelson: near the Tetsa River crossing at km 585, and ~4.5 km west of Toad River at the "Poplars" campsite.

The focus of the study was on soils currently or recently containing permafrost as well as associated soils on nearby sites with warmer microclimates, with a total of 6 pedons described and sampled. One of these, an Organic Cryosol (pedon BC12-08), was documented in a short paper:

Sanborn, P., C. Bulmer, M. Geertsema, and S. Smith. 2022. A proposed Folic subgroup for the Organic Cryosols. Canadian Journal of Soil Science 102: 811–816. https://doi.org/10.1139/cjss-2021-0182

Associated soil microclimate monitoring occurred at this site, and is documented in:
Hasler A., Geertsema M., Foord V., Gruber S., Noetzli J. 2015. The influence of surface characteristics, topography and continentality on mountain permafrost in British Columbia. The Cryosphere 9: 1025–1038. https://doi.org/10.5194/tc-9-1025-2015

Some of the data from both papers was presented as a poster at the Canadian Society of Soil Science annual conference in 2013.

The highlights of the 2022 paper were presented at an online meeting of the Soil Classification Working Group of CSSS on January 20, 2023.

The sequence of site numbers is BC12-08, -09, (-10 was not used), -11, -12, -13, -14, and -15. Note that BC12-13 was described and sampled, but not photographed. An additional pedon designated as BC12-13A was located within ~10 m of BC12-13 on the same terrace, and had what appeared to be a buried fire-reddened layer under a possible buried Ah horizon. This pedon was photographed but not described or sampled.

Fonds consists of the research and professorial records of Dr. Joselito Arocena, a founding faculty member of UNBC. Arocena was an internationally-recognized soil scientist and UNBC’s first Canada Research Chair. His records demonstrate his accomplishments as an academic and researcher, as well as his many and varied interdisciplinary research endeavours. Also included are selections from Arocena’s extensive photographic slide collection which illustrate his teaching, research projects, and personal interests.

The Kluane Lake area of SW Yukon was a continuing focus of Dr. Paul Sanborn's research for more than a decade, and generated several productive collaborations. Key themes included biological soil crusts in boreal grasslands, and interactions between aeolian sediment deposition, slope processes, and fire in boreal grassland and forest soils.

The 2003 field work with Darwyn Coxson was a pilot study to assess the types and distribution of biological soil crusts in boreal grasslands in the Kluane Lake area. Eight sites were visited at which the team sampled the crust and the uppermost A horizon immediately underneath it. Note that site numbers Y03-03, -04, -05, -06, -07, -09, -10 and -12 were indicated as sites 3, 4, 5, 6, 7, 9, 10 and 12 in Table 1 of Marsh et al. (2006). Additional crust sampling was conducted at two additional sites (“Peninsula”, “Silver City”) in 2004; details of sampling methods and site locations are in Marsh et al. (2006).

Results from 2009 field work were presented in Sanborn and Jull (2010), along with soil charcoal radiocarbon dates from 2003-2008 sampling which were used to reconstruct fire history in the Kluane Lake area. The 2003 (a single site at Silver City), 2004, and 2008 field work consisted of a reconnaissance of grassland and forest sites across a range of aspects and slope positions in order to recover buried soil charcoal.
