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.
The key results from the study were later published as:

This digital document is a scanned PDF of a Prince George Forest Region Forest Research Note #PG-12-1: "Experimental Project 660 - 30-year Progress Report - Buckhorn Installation".
"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.

This born-digital "Profile Descriptions" document provides descriptions of Williams Lake (Skulow Lake), Aleza 1 & 2, Log Lake, and Lucille Mountain pedons.
The BC Ministry of Forest's EP 1148 Long-term Soil Productivity (LTSP) study addresses two key factors— soil porosity and site organic matter—that potentially limit tree growth and site productivity in the timber-harvesting land base and that can be affected by forestry operations.
This establishment report for EP 1148, "The effects of soil compaction and organic matter retention on long-term soil productivity in British Columbia (Experimental Project 1148)", is accompanied by a floppy disk containing 12 data sets (see 2023.2.2.11.2).
This born-digital document provides a description of the Topley LTSP site pedon.
This document is a photocopy of a 1994 draft report prepared by Scagel, Hickling, and Evans for BC Ministry of Forests, Silviculture Branch. The document includes annotations by Lorne Bedford, BC MoF (ret.).
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.

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".
File consists of memoranda from Per Saxvik to Bell-Irving regarding "Fraser River Flow Analysis with Reference to Fish Passage Capacity through the Main Fishways at Hell's Gate". Also includes a "Fraser River Canyon Fish Passage Summary Report (June 1988) Updated October 1989" by Per Saxvik of SEP Engineering.
File is a Resource Folio of maps and accompanying information created by Northwood Pulp & Timber regarding Timber Sale Harvesting Licence A01847, Willow River Block, Willow River P.S.Y.U. Includes maps that depict ungulates, waterfowl, recreation areas, special influence areas, and timber types. Most of the sheets have a duplicate, some with very slight variations. The following maps are supposed to be included in the but were missing upon arrival at the Archives: fish & topography, cutting permits & roads, and soils.
Photographs are panoramas taken from the Churchill BC Forest Service Lookout, located at latitude 54°04' and longitude 122°16'. The photographs were bound together and include a transparent grid that was intended to be used for locating forest fires.

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.
