Yukon Delta, satellite image. North is at upper left. Vegetation is green, water is dark blue, and ice is pinkwhite. The Yukon Delta has formed from sediments deposited by the Yukon and Kuskokwim rivers as they flow into the Bering Sea on the western coast of Alaska, USA. The delta supports a wide variety of wildlife on shore and offshore, where sheets of sea ice form during the coldest months of the year.
