Abstract
The 30 M m3 rockslide that occurred on the east face of Turtle Mountain
in the Crowsnest Pass area (Alberta) in 1903 is one of the most famous
landslides in the world. In this paper, the structural features of
the South part of Turtle Mountain are investigated in order to understand
the present-day scar morphology and to identify the most important
failure mechanisms. The structural features were mapped using a high
resolution digital elevation model (DEM) in order to have a large
overview of the relevant structural features. At the same time, a
field survey was carried out and small scale fractures were analyzed
in different parts of southern Turtle Mountain in order to confirm
the DEM analysis. Results allow to identify six main discontinuity
sets that influence the Turtle Mountain morphology. These discontinuity
sets were then used to identify the potential failure mechanisms
affecting Third Peak and South Peak area.
