Photographs of mountaineering and other mountain adventures in Garibaldi Provincial Park, the Cariboo Range, Coastal British Columbia, and the United States.
There is 1 slide that was removed from broken glass (0093) and another that is not a glass slide (0099).
These slides seem to be colour-coded through using tape to frame the slides:
Blue is the Garibaldi region.
Yellow or Red seem to be other areas in British Columbia, and possibly Washington, but for different years (red = 1949, yellow = 1950).
Green indicates areas in the United States, such as Arizona and Colorado.
There are some slides that have 2 different tape colours.
