TOPIC: A PETROLEUM GEOLOGIST LOOKS AT THE FRANK SLIDE
More than 100 years have passed since the catastrophic Frank Slide at Turtle Mountain, Crowsnest Pass, Alberta. The visible engineering and mechanical aspects of the disaster (how it occurred) have been studied and explained by Professor Cruden and his students at the University of Alberta. However, interpretation of the internal geology of Turtle Mountain has changed little since the Geological Survey of Canada published its findings in 1912.
From the 1950's onward, petroleum exploration in the Alberta foothills has shown that the subsurface geology of structures like Turtle Mountain was very different from interpretations based on downward extrapolation of the visible characteristics. Turtle Mountain is similar to structures such as the Moose Mountain, Savanna Creek, and Waterton gas fields whose geological re-interpretation was based on drilling and seismic data. Re-interpretation of Turtle Mountain along similar lines alters our perception of why the Frank Slide happened.
Although mining was undoubtedly the immediate trigger for the slide, the blame does not necessarily lie with the mine's owners. Understanding of the internal geology of Turtle Mountain had yet to come. Current exploration for oil and gas will lead to a fuller understanding of the subsurface geology of the Crowsnest area, and with it, the internal structure of Turtle Mountain.
