The large tapestry and 3 smaller framed collages are concerned with the Glenrose Cannery, a salmon cannery built on top of an ancient village and archaeological site on the Fraser River. The title, “Pressure, Light, Oxygen: Glenrose Cannery,” refers to how the tapestry was made and also the conditions affecting the visibility of material at the site. Pressure: paint rubbings, Light: cyanotypes, Oxygen: hand dyed and found indigo. This small area of land was used more or less continuously for around 9,000 years and encompasses the full range of human presence on the Northwest coast, from First Nations hunters and villagers to European and Asian cannery workers. The cannery was torn down, the shoreline capped with boulders, and the midden covered by a highway as part of the South Fraser Perimeter Road development between 2011-2014.
