This paper deals with mass movements resulting from hillslope instability and sediment yields of mass movements, derived from evidence of sedimentation rates in lakes. The purpose of this paper is to look into and compare different mass movement and lake sedimentation researches and to gain knowledge of the geomorphology of some mountain ranges in British Columbia, with an emphasis on the southern Coast Mountains. The paper will first present and discuss results of different articles which were examined. These articles dealt mainly with mass movements, especially debris flows and landslides in the Coast Mountains and sedimentation in lakes in southwest and south central British Columbia. Research on debris flows, landslides and lake sedimentation will be looked into separately. After this, two specific researches that were attended by the author will be described. One deals with landslide mapping in the Capilano Watershed north of Vancouver and the other deals with sedimentation rates in Green Lake near Whistler. These researches are both performed by graduate students from the University of British Columbia in Vancouver, Canada. Assistance for the fieldwork-part of these two researches was given by the author from June to October 2000, as part of the undergraduate program of Physical Geography studies at the University of Utrecht in the Netherlands. In the last part of the paper, the attended and studied researches will be compared with previous researches and discussed, followed by some conclusions.
