About this map

Susitna Delta and the intricate alluvial landscape where the Susitna River meets the Pacific Ocean define this survey of the northern Cook Inlet coastline. The terrain is a complex network of tidally influenced waterways and wetlands, including the extensive Beluga Slough and the Ivan River. The presence of Indigenous Dena'ina place names like Susni Kaq', Yach'ditnu, and Qalnigi Denuch'dnel'ushtnu provides critical cultural and geographic context for the Matanuska-Susitna region, marking traditional landmarks alongside major landforms like Big Island and Barrel Island. This 2013 data illustrates a dynamic coastal environment where freshwater systems like Fish Cr and Stump Lake integrate with the shifting silt and channels of the delta.
