Norton Sound is an inlet of the
Bering Sea on the western coast of the
U.S. state of
Alaska, south of the
Seward Peninsula. It is about 240 km (150 mi) long and 200 km (125 mi) wide. The
Yukon River delta forms a portion of the south shore and water from the Yukon influences this body of water. It is ice-free from June to October.
