Paper Summary:

The following paper looks at the Lemieux landslide that unfolded near Casselman, Ontario, in June of 1993. In particular, the writer looks at the geo-morphological history of the region wherein the slide took place and what characteristics of the local landscape made the landslide possible. Furthermore, the paper discusses how the local topography has changed since 1993 and the extent to which the academic literature has been able to offer new insights into the characteristics of the curious Leda Clay that makes landslides in the region of Casselman, Ontario relatively commonplace. Finally, the paper delves into what sort of financial incentives might be propelling research into the stability of the Lemieux Landslide territory and what the likely prospects are for successful development.

From the Paper:

"Because Robinson's article pertaining to the Lemieux Landslide was penned less than three years ago, it remains worthwhile reading for those interested in how the site has changed in the intervening several years. To start with, Robinson informs his readers that there has been considerable erosion of the once-daunting sides of the crater, and re-vegetation has taken place on various spoil piles. Not to be overlooked, the South Nation River has carved an incision into the remaining debris. Despite these changes, one does not have to look for very long to see how many of the striking features of the original landslide - most notably its length and the considerable width of its destructive swath - remain conspicuous.
"At this juncture, some more time should be devoted to the Lemieux Landslide's history - or, to be more specific, the events that made the 1993 landslide possible. To begin with, Robinson's discussion of the curious Leda clay found in large quantities in the area deserves more elaboration."
