The Yana River Delta in northern Russia • Earth.com

Today’s Image of the Day from NASA Earth Observatory features the soggy Yana River Delta in northern Russia, where snow cover has retreated and exposed brown, swampy tundra.

The deeper lakes look white from floating ice, while other lakes appear greenish-yellow from decomposing vegetation and algae that have colored the ice.

This region contains evidence of mammoth hunting that took place 27,000 years ago, which represents the oldest known human presence in the Arctic.

The image was captured by the Operational Land Imager (OLI) on Landsat 8 on June 18, 2018.
