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.

Research results appeared in these publications:

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.
