"Another expression of the high morale which prevailed was a joint project which we pursued after hours, on our own time. Out of one huge spruce log we made a set of furniture using an axe and a crosscut saw. We made chairs, a table and a sofa." -- quote from Cedric W. Walker (1907-2003) in "An Early History of the Research Branch, British Columbia Ministry of Forests and Range" (p. 48)

Part of Cassiar Asbestos Corporation Ltd. fonds

File contains images of mine operations and construction, as well as a variety of other subjects.

  • Elements of the underground mine are depicted, including miners working, the marked rock face, yellow ducting and ventilation fan, the portal, mesh rockbolted onto adit walls, shotcrete being applied, and stacked mining construction materials.
  • Mining equipment depicted in this file includes underground ore haulage truck, Wabco ore haulage truck, jackleg drill, stoper drill, scoop tram, jumbo drill, conveyor, pickup trucks, unidentified mixing or grinding machine, a cable wagon and half constructed ore haulage truck in the shop, and a continuous miner (also known as alpine miner or roadheader).
  • A set of images show a dozer and a lowbed truck transporting a temporary building down the pit mine access road.
  • Several images depict drill core fragments, asbestos ore, and geological features of the mine.
  • Mining related process are depicted, including a young man sluicing and panning, a mine building under construction, and an unidentified steel frame structure with a hydraulic device suspended on a rail.
  • A set of images shows a railway or highway construction project, including stockpile of construction materials, rail cars, caboose, locomotive, front end loader, dump truck, concrete mixing trucks, semi-trucks, and a rail car with large steel drums which are speculated to be specialized for tunnel construction.
  • Further images show what is speculated to be tunnel construction.
  • A set of images at a high ceiling underground mine which is not Cassiar depicts a man in a suite by a underground ore haulage truck, and other mining vehicles including a crane.
  • A set of images depict an ungulate herd, possibly bighorn sheep, on a mountain side.
  • The file includes several images which depict personal life, presumably from a family vacation, and access to these images may be restricted. These images depict man with children on a fishing trip, adults and children around a pool, a woman on a motorcycle, and a house and kitchen. Several groups of images are contained in envelopes annotated with dates and “K. Minty”.

Part of Dr. Paul Sanborn fonds

The Sulphur stable isotope tracer study (E.P. 886.15) field experiment was installed in young lodgepole pine stands at two sites in the Prince George Forest Region in 2001, with fertilizer treatments applied in late 2002. These sites are designated as Kenneth Creek (east of Prince George) and Holy Cross (south of Fraser Lake). (The Kenneth Creek installation was established near plots of the older E.P. 886.13 in the same stand.) Full experimental details, including pretreatment soil and foliar date, were given in:

Sanborn, P., R.P. Brockley, B. Mayer, M. Yun, J. Prietzel. 2005. Sulphur fertilization of lodgepole pine: a stable isotope tracer study (E.P. 886.15): Establishment report. Tech. Rep. 020. B.C. Min. For., Res. Br., Victoria, BC. http://www.for.gov.bc.ca/hfd/pubs/Docs/Tr/Tr020.htm

The Kenneth Creek site was attacked by mountain pine beetle in 2006, resulting in at least 80% tree mortality. In 2013, the stand was levelled in order to enable replanting, and due to poor communications within the Ministry of Forests, the opportunity to salvage this installation was lost. The Holy Cross site was hit by a wildfire in 2010, and most of the research plots were destroyed.

Preliminary results from foliar analysis, sufficient to demonstrate that our stable isotope tracer approach could detect fertilizer uptake, were published in:

Sanborn, P.T., R.P. Brockley, and B. Mayer. 2011. Stable isotope tracing of fertilizer uptake by lodgepole pine: foliar responses. Can. J. For. Res. 41: 493-500. https://cdnsciencepub.com/doi/full/10.1139/X10-222
