Abstract

Contiguous catchments are linked by a pass at 1015 m asl, which represents the maximum elevation of the outburst conduit. During Cordilleran Ice Sheet decay, the normal meltwater drainage pathway to the south in Siverhope valley was blocked by a dead ice dam. Consequent catastrophic discharges flowed from Post Creek into Chilliwack valley. Radiocarbon ages from Chilliwack valley, and outburst sediments deposited against the distal side of the end moraine that dams Chilliwack Lake are used to infer that outburst occurred about 11.4 ka.
