Abstract

Landslide-damming of Silver Lake in the Cascade Mountains took place about 1000 BP. Delta growth favoured the faulted west valley side. At the commencement of logging activity in AD 1946 the course of Silverhope Creek was diverted away from access roads. As a consequence, the channel shifted from the west side to the east side of the valley, forming a new delta. Six gravity lake cores and SCUBA surveys of lake sediments reveal changes in the depositional regime. In two cores, late Pleistocene-early Holocene sediments are preserved. Old delta abandonment, new delta growth, reorientation of turbidity channels and confluence zones are discussed.
