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.

File contains photographs depicting close view of drill bits used in the Cassiar mine. The photos were taken for documentary purposes during an evaluation procedure in which the bits were tested and compared. 32 of the photos are adhered to three reports containing detailed analysis of the condition and function of the drill bits used. Reports were addressed to "E. Komperdo / Assist. Mine Superintendent, Production," and were sent by "Bob Clark / Industrial Engineer" and "E. Isaaks / Engineer Trainee." All of the photos are heavily annotated on verso and recto, often documenting the date, bit number, drilling depth, and notes on general condition.

Image depicts the Terzaghi Dam viewed from the downstream side near Bralorne B.C.

Image depicts the Lajoie hydroelectric generating station at the Lajoie Dam on the Bridge River (view of powerhouse and tailrace from top of dam).

Photograph depicts part of the vacuum dust control and removal system in the Cassiar mill building. Unidentified man can be seen at rotary air-lock, in which heavy blown dust would collect before dropping to plenum conveyor resting just above floor. From here, the dust would eventually be expelled at the tailings pile outside of the mill. Second unidentified man can be seen climbing steps in background. This section of the mill was located above the lab.

Photograph depicts Zora Ivanovska in safety gear, vaccuming asbestos dust from "hall screen" in mill (slanted vibrating tables with varying mesh sizes, used to separate different lengths of fibre). Mill General Foreman Tony Pinto is visible on far right, with unidentified man.

Photograph depicts three women wearing white aprons while conducting tests on asbestos fibre in lab area, miscellaneous equipment throughout room.

Image depicts the Lajoie Dam on the Bridge River, upstream side, showing part of Downton Lake and, in the foreground, the spillway intake.

Photograph depicts palletizer machinery, where bags of asbestos fibre were shrink-wrapped and made ready for shipping pallets. Palletizer was located near shipping (believed to be in mill building). Unidentified man visible in machinery on far left.

Photograph depicts Joseph wearing safety gear while standing at testing equipment on raised sampling station. Sign below Joseph reads "DO NOT DISTURB / SAMPLING IN PROGRESS / PROPERTY OF ENVIRONMENTAL CONTROL DEPT. / CASSIAR ASBESTOS LTD." Helen Joseph took air quality tests in the working areas and town (see item 2000.1.1.3.19.135). Power lines, unidentified building, and mountain base visible in background. Photo was taken during winter.

During the 1980s, Agriculture Canada pedologists Scott Smith (retired from Summerland Research Station, formerly based in Whitehorse) and Charles Tarnocai (retired from Central Experimental Farm, Ottawa) had a large field program which addressed the trends in soil development in the central Yukon. Across this region, particularly between Whitehorse and Dawson City, the land surfaces and surficial deposits vary greatly in age due to the differing extents of glaciations over the past ~2 million years.

Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr. Paul Sanborn, and this resulted in a student project published as:
Daviel, E., P. Sanborn, C. Tarnocai, and C.A.A. Smith. 2011. Clay mineralogy and chemical properties of argillic horizons in central Yukon paleosols. Canadian Journal of Soil Science 91: 83-93. https://doi.org/10.4141/cjss10067

This data set consists of transcribed data from lab data sheets, showing McQuesten-Dawson City paleosol data from the Tarnocai and Smith 1983 AAFC Yukon Paleosol Study. The data set includes chemical and particle size data for Tarnocai & Smith samples, as determined by the Ag Canada lab. Note that the “Site” column indicates the NTS topographic map sheet (e.g. 115P/13) for the sampling locations.
