Collection consists of photographs and an accompanying notebook documenting Chambers’ and the BCMC’s pioneering mountaineering activities and exploration during the period 1947 to 1968. Unlike the Rocky Mountains of Canada, the Coast Mountains were late in being explored by mountaineers. During the period recorded in these photographs, much of the region remained little visited, and the exploration lasted into the 1980s. As a result, the photographic record of mountain exploration in the Coast Mountain region is relatively poor and fragmentary, especially for the period from the late 1930s through the 1950s. The Chambers collection fills several gaps in this record.

Chambers was meticulous in recording the details of each image he captured with his Zeiss Ikon camera – every slide is identified with the location, names of individuals, and the date. An accompanying notebook lists the photographs taken on each roll of film and includes additional technical information. Further documentation of many of these trips is available in BCMC newsletters and issues of the Canadian Alpine Journal.
