A 300-meter-thick section of Eureka Sound Formation beds north of Stanwell-Fletcher Lake, Somerset Island, contains well-sorted fine-grained quartz sandstone beds in which deformed crossbedding occurs. It is concluded that the deformation was caused by variable drag exerted on individual beds by flowing masses of sediment following current scouring action upstream. The gradational change in a single bed, from ordinary stream crossbedding at the base of the bed to an overturned fold at the top suggests that the sediment flow occurred at or just above standing water level.
