2024 Map of Cordova B-3 NE

About this map

Chugach National Forest land dominates this section of the Alaskan coastline, where the massive Copper River delta meets the Gulf of Alaska. The landscape is defined by a complex network of glacial meltwater and tidal flux, characterized by the shifting braids of Hotcake Channel and the convergence of the Martin River. The Copper River Highway skirts the northern edge of the map, providing a vital land link across this saturated terrain. The mapping reveals a transition from the forested slopes of the coastal range to the low-lying wetlands and sandbars of the delta, including distinct landmarks like Heart Island. This 2024 data represents the contemporary state of one of the most dynamic river systems in North America, where sediment deposition continually reshapes the drainage patterns of Sheep Creek and the surrounding marshlands.
