The two images show the same branch of the Mississippi River. On the top right, a nearby town is visible, noticeable by its traditional geometrical street grid. The river is almost entirely frozen and the nearby ground is covered in snow on the picture on the left, while the river is a dark blue and the snow has melted on the picture on the right. The stark difference in colours between the two seasons makes for a visually interesting comparison.

What a difference a few months make. Did you know the Mississippi river is the fourth largest river by drainage in the world? The word itself comes from the French rendering of the Anishinaabe name for the river, Misi-ziibi, which means "Great River".

The image of the river on the left was taken by Sentinel 2 (Copernicus program) on January 2017, the image on the right is from March.
