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 in size,〔 it is one of the largest deltas in the world. It is larger than the Mississippi Delta (which varies between ), and comparable in size to the entire U.S. state of Louisiana (). The delta, which consists mostly of tundra, is protected as part of the Yukon Delta National Wildlife Refuge. The delta has approximately 25,000 residents. 85% of these are Alaska Natives: Yupik Eskimos and Athabaskan Indians. The main population center and service hub is the city of Bethel, with an estimated population of around 6,219 (as of 2011).〔http://quickfacts.census.gov/qfd/states/02/0206520.html retrieved Nov 16, 2012〕 Bethel is surrounded by 49 smaller villages, with the largest villages consisting of over 1,000 people. Most residents live a traditional subsistence lifestyle of hunting, fishing, and gathering. More than 30 percent have cash incomes well below the federal poverty threshold. The area has virtually no roads; travel is by Bush plane, or by river boats in summer and snowmachines in winter. Bethel is the location of the Yukon Kuskokwim Correctional Center.〔(Alaska Dept of Corrections )〕 Image:YukonDelta ASTER 2002may26.jpg|False-color ASTER image of the Yukon Delta.
