Description :
The aim of this paper is to describe observations of the initiation and development of two active-layer detachments at Big Slide Creek, BSC, in August 2005. While one conformed to the pre-existing notion of almost instantaneous formation, the other did not. The progressive expansion of the latter failure over several days helps confirm the origin of some structural features previously observed within active-layer detachments and provides an indication of geotechnical conditions during failure.
