The Yukon Delta is a river delta formed by the Yukon River as it drains into the Bering Sea. It is part of the larger Yukon–Kuskokwim Delta, which includes the delta of the Kuskokwim River. The Yukon River rises in British Columbia, Canada, and flows through Yukon before entering the U.S. state of Alaska. This August 2017 satellite image of the Yukon Delta shows how the river branches into numerous distributary channels that meander through the low-lying terrain on their way to the sea. The sandy colour of these channels and the coastal water is indicative of the marine sediment the river carries to the sea at this time of year.Photograph credit: European Space Agency / Sentinel-2
