Operation Bow-Athabasca

The Canadian Rockies, with their rugged mountain peaks and alpine meadows, are a major tourist attraction. The southern Canadian Rockies, which are designated as a UNESCO World Heritage Site, were the focus of a major Geological Survey of Canada research project during the summers of 1965 and 1966. Called Operation Bow-Athabasca, the goal was to systematically study and map the region’s geology. Its project leader Raymond Price was to go on to become the Survey’s Director General in 1982.

The use of a two-passenger helicopter to deploy ten geologists enabled the study and mapping of this huge area, which totalled about 27,000 square kilometres. This allowed the team to accomplish as much in the two summers’ work as could have been done in two decades using earlier-style packhorses and foot traverses.

Operation Bow-Athabasca produced 39 1:50,000 scale geological maps with cross-sections that explained the nature and evolution of the Canadian Rockies. It also provided insights into the formation of similar mountain belts found elsewhere.
