During a year away from studies in 1987-88, Dr. Paul Sanborn developed a successful grant proposal to the Science Council of BC (SCBC) to pursue a postdoctoral project with Dr. Tim Ballard in relation to sulphur-deficient soils in BC and prescribed fire. This project built on an existing broadcast burning study conducted by Macmillan Bloedel Ltd. near Port Alberni on Vancouver Island, led by Bill Beese (later at Vancouver Island University). Dr. Sanborn's work addressed sulphur forms and amounts in the soils at these sites, and the chemical processes influencing sulphur availability in relation to prescribed fire.

Only one part of this work was eventually published:
Sanborn, P.T. and T.M. Ballard. 1991. Combustion losses of sulphur from conifer foliage: Implications of chemical form and soil nitrogen status. Biogeochemistry 12: 129–134. https://doi.org/10.1007/BF00001810

The remainder of the work was documented in this Project Completion Report to SCBC, dated February 28, 1990, and entitled "Effects of Prescribed Fire on Sulphur in Forest Soils".

In the mid-1990s, Dr. Paul Sanborn worked with Dr. Lito Arocena of UNBC to assemble and interpret basic physical, chemical, and mineralogical data for typical soils at important long-term forestry research sites in central and northeastern BC. The key results were published as:

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.

This grew out of a field trip with Ministry of Forests range personnel to the Stikine and Tuya River valleys, near Telegraph Creek BC on August 27-28, 2007. (Two pedons were sampled in 2007, BC07-03 and BC07-04, but those results were not included in the paper.)

In August 2008, Dr. Paul Sanborn returned to the Stikine to sample pedon BC08-06, after field work in Yukon which collected the other two pedons used in the paper, from near Carmacks (Y08-39) and Kluane Lake (Y08-41). (An additional pedon from Kluane, Y08-43, was sampled and analyzed, but it was from a forested site and was not included in the paper.)

With the assistance of the Yukon Geological Survey, Dr. Paul Sanborn was able to visit the terminus of the Klutlan Glacier, a major outlet glacier which originates in the Alaska portion of the St. Elias Mountains. The stagnant terminus has a thick cover of debris, including a large component of White River tephra, providing enough soil material to support a boreal forest. Field work occurred on July 8, 2007, and results were published as:
