The key results from the regional soil mineralogy study were later published as:

While at the Ministry of Forests, Dr. Paul Sanborn carried out two retrospective studies which examined soil chemical properties at long-term silvicultural research sites where different vegetation types had been created, either as planned or unplanned experiments. These studies were Experimental Project (EP) 660 and a research project at the Archie Creek site.

In July 2009, Dr. Paul Sanborn undertook the first soils field research at the Fort Selkirk volcanic field in central Yukon, with helicopter support and funding from the Yukon Geological Survey. This document is a complete transcription of field notes, with
soil and site photographs.

File contains correspondence regarding funding for research project and computer generated maps.

Item is a "Soil Survey Report on Part of Aleza Lake Forest Experimental Station" by R.A. Fisher of the Forest Surveys Division, British Columbia Forest Service.

With support from the Muskwa-Kechika Trust Fund as a Seed Grant, Dr. Paul Sanborn carried out a pilot study of soils in relation to prescribed burning in the Northern Rocky Mountains, in collaboration with Perry Grilz, then a Range Officer in the Ministry of Forests. Sanborn and Grilz conducted 3 days of field work in July 2001. Sanborn wanted to test the utility of plant-derived opal (phytoliths) as a soil indicator of vegetation history, in the hope of distinguishing natural grasslands from those created by anthropogenic burning.

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.
