The westward journey of the mighty Yukon River takes it from its headwaters in Canada’s British Columbia straight across Alaska. The river has many stories to tell, of generations of Indigenous people hunting on its banks and fishing in its waters, of paddle-wheeled boats and gold panning and pipelines.
Where it meets the Bering Sea, the river fans out into an intricate delta resembling cauliflower lobes of river channels and ponds. The delta has a story to tell, too — that of an increasingly green Arctic.
A composite image of the delta’s northern lobe, taken May 29 by the U.S. Geological Survey’s Landsat 8 satellite, shows willow shrublands lining river channels as they wind toward the sea. Farther inland, tussock grasses carpet the tundra. Grasslike sedge meadows populate low-lying wetlands, punctuated by ponds left behind by springtime floods along the riverbanks from snow and ice that have melted upstream.
