Abstract

Glacial retreat and opening of Taan Fjord (an arm of Icy Bay, Alaska) in the last two decades drove a base level fall of 400 m at the outlets of 4 tributary valleys in the region of the current Tyndall Glacier terminus. Response in the tributary valleys to this base level fall includes evacuation of stored sediment, incision of slot gorges into bedrock, and landsliding on valley walls. Fluvial transfer of eroded bedrock, glacial deposits and stored nonglacial fluvial deposits after 1983 resulted in progradation of fan deltas toward the fjord centerline
