Abstract
In August 2008, reactivation of the Little Salmon Lake landslide occurred.
During this event, hundreds of conical mounds of variable size and
composition formed in the deposition zone. The characteristics of
these landforms are described and a potential mechanism for their
formation is proposed. A preliminary slope stability analysis of
the 2007 Mount Steele rock and ice avalanche was also undertaken.
The orientation of very high persistence (>20 m long) structural
planes (e.g., faults, joints and bedding) within bedrock in the source
zone was obtained using an airborne-LiDAR digital elevation model
and the software COLTOP-3D. Using these discontinuity orientation
measurements, kinematic, surface wedge and simple three-dimensional
distinct element slope stability analyses were performed.
