2017 Map of Icy Bay D-1 NW

About this map

The Gulf of Alaska defines the western edge of this coastal environment, where glacial runoff and oceanic tides meet in a complex network of braided waterways. The landscape is dominated by the sprawling deltas of the Yahtse River and the Caetani River, which weave through low-lying wetlands and alluvial flats. Offshore, the isolated Gulf Island sits within the protective boundaries of the Alaska Maritime National Wildlife Refuge, highlighting the region's role as a critical habitat for migratory species and marine life. This 2017 survey captures a remote wilderness largely untouched by permanent settlement, where the shifting courses of the Yahtse River suggest a dynamic, ever-changing coastline shaped by the powerful forces of the North Pacific.
