Saskatchewan averages about 430 wildfires a year which burn over an area of about 274 000 ha according to provincial records for 1960-85. Many fires occur in the Precambrian Shield region of the province. A small number of these fires have exhibited extreme fire behavior and subsequently developed into 'Class E' (i.e., >200 ha.) or campaign fires. In response to a concern expressed by local fire managers about certain so-called "unique" aspects of rating fire danger in the Shield country, a case study of wildfire behavior was recently completed by the first author, with particular emphasis on the associated climatic and meteorological conditions, and the applicability of the Canadian Forest Fire Danger Rating System (CFFDRS) (Alexander 1982a, 1985b, 1986a). This paper documents the results of the analyses. The 1980 Chachukew Fire occurred in the east-central region of the province, 6 km north of the town of Pelican Narrows (Fig. 1). This fire was selected for analysis because documentation was readily available from a review, completed shortly after the fire was declared out, by W. E. Dodds at the request of the Saskatchewan Department of Parks and Renewable Resources (SDPRR). The format of the case analysis is similar to that of Alexander et al. (1983).
