McLaren in 1962.〔Belyea, H.R. and McLaren, D.J., 1962. Upper Devonian formations, southern pan of Northwest Territories, northeastern British Columbia and northwestern Alberta. Geological Survey of Canada, Paper 61-29.〕 ==Lithology== The Kakisa Formation is composed of silty and dolomitic limestone. 〔 〕 Reef builders such as corals and stromatoporoids can be identified in the formation.
