Espenberg is a historic Iñupiaq settlement and present-day fish camp at Cape Espenberg, a peninsula composed of a series of dune-covered beach ridges on the Chukchi Sea coast of the Seward Peninsula that extends eastward into Kotzebue Sound, about 63 miles (101 km) east-northeast of Shishmaref and 43 miles (69 km) southwest of Kotzebue, Alaska.

Sudden Stream drains the Malaspina Coastal Plain, flowing generally south for 2 miles (3.2 km) from the outlet of Malaspina Lake, a proglacial lake at the terminus of the Malaspina Glacier, to a lagoon formed by a barrier spit called Schooner Beach on Yakutat Bay, about 207 miles (333 km) east-southeast of Cordova and 18 miles (29 km) northwest of Yakutat, Alaska.

The Elwha River starts from a perennial snowfield at an elevation of 4,763 feet (1,452 m) in the Olympic Mountains and flows generally north for 45 miles (72 km) to Angeles Point at Freshwater Bay on the southern shore of the Strait of Juan de Fuca, about 33 miles (53 km) east-southeast of Clallam Bay and 6 miles (10 km) west-northwest of Port Angeles, Washington.
