Description :
This paper deals with the glacial history of northern Baffin Island. Its main focus is the glacial bedforms and debris dispersal attributed to the Steensby Inlet flow event, which is interpreted as an ice stream. Antecedent conditions are illustrated based on recent mapping. The evolution of the ice cover, including its thickness, flow patterns, moraine construction, debris dispersal and inferred ice streams, is presented. The Steensby Inlet flow event and inferred ice stream are then discussed. Finally, the paper details the devolution of the ice stream into streams of decreasing size and discusses associated corridors of evacuation and lateral sliding scarps.
