Report on the Great Landslide at Frank, Alta., 1903
30 April, 1903, a day after the Frank Slide, the Superintendent of
Mines in the Canadian Department of the Interior instructed two senior
staff of the Geological Survey of Canada (R.G. McConnell and R.W.
Brock) to investigate the catastrophe. Their report was published in
1904 and has been out-of-print for a long time. EGS decided to reprint
this report on the occasion of the centennial of the Frank Slide in
McConnell and Brock’s conclusion was that the slide was
due to a combination of causes the chief of which, the structure and
condition of the mountain, was aided by exceptional atmospheric and
other natural conditions. The condition of the strata before the slide
was affected by slight readjustments attendant on mining operations.
The careful contemporary account of the landslide's impact on Frank is
still one of the very few available for risk assessment studies. The
book is a must for anybody interested in landslides.
The book includes a reproduction of the original geological map.
