| Summary | (Plain Language Summary, not published)
This guidebook highlights sensitive clay landslides at five locations situated just north of the Ottawa River within the municipalities of Pontiac,
Bristol and Clarendon, Quebec, to the west of Ottawa-Gatineau. The landslides form major geomorphic features in the landscape that are easily overlooked, but are readily apparent on shaded relief maps. The sites include the Quyon Valley landslide,
one of the largest sensitive clay landslides in eastern Canada. All five locations are easily accessed and viewed along roads without intruding onto private property. |
