Salt marsh in southwestern Kazakhstan •

Last update: October 1st, 2020 at 2:00 pm

Today’s Image of the Day from the European Space Agency features the edge of a salt marsh near the Caspian Sea in southwestern Kazakhstan. 

The salt marsh was once a permanent gulf in the northern part of the Caspian Sea, which has the most salinity. 

Over the last few decades, the marsh gets occasionally cut off from the main body of water due to fluctuating sea levels.

The water appears to have evaporated in this image, leaving behind a white salty landscape.

The central part of the photo is dominated by rock formations, while the grey boundary between the land and salt marsh gets its color from sedimentary runoff mixing with the saltwater.
