Delta Bloom: The Lena River Tundra

A Frozen Wetland

The Lena River Delta is a sprawling expanse covering over 30,000 square kilometers in the Russian Arctic. For about 7 months of the year, it is a frozen, solid landscape. However, during the brief Siberian summer, the delta thaws and transforms into a lush wetland, its myriad streams and channels creating breathtaking patterns visible from space.
