Yukon–Kuskokwim Delta

The Yukon–Kuskokwim Delta is a river delta located where the Yukon and Kuskokwim rivers empty into the Bering Sea on the west coast of the U.S. state of Alaska. At approximately 129,500 square kilometers (50,000 sq mi) in size, it is one of the largest deltas in the world. It is larger than the Mississippi Delta (which varies between 32,400 and 122,000 square kilometers (12,500 and 47,100 sq mi)), and comparable in size to the entire U.S. state of Louisiana (135,700 square kilometers (52,400 sq mi)). The delta, which consists mostly of tundra, is protected as part of the Yukon Delta National Wildlife Refuge.
