NASA’s Landsat 8 satellite captured Lake Saimaa, Finland. In April, melting of the ice has started.

Saimaa is a lake located in the Finnish Lakeland area in southeastern Finland. At approximately 4,279km2, it is the largest lake in Finland, and the 4th-largest natural freshwater lake in Europe. It was formed by glacial melting at the end of the Ice Age. Major towns on the lakeshore include Lappeenranta, Imatra, Savonlinna, Mikkeli, Varkaus, and Joensuu. About 6,000 years ago, ancient Lake Saimaa, estimated to cover nearly 9,000km2 at the time, was abruptly discharged through a new outlet. The event created thousands of square kilometers of new residual wetlands. An endangered freshwater seal, the Saimaa ringed seal, lives only at Saimaa. Another of the lake’s endangered species is the Saimaa salmon.
The local scenery on the ground is as follows.
