English: This image, acquired on 19 April by one of the Copernicus Sentinel-2 satellites, depicts Lake Saint Clair, one of the Great Lakes of North America. During the winter months, the lake's climate is shaped by cold air masses from the Article Circle, resulting in the formation of sea ice in the lake's waters and heavy snowfall in surrounding areas. As spring arrives and the thawing process begins, Lake Saint Clair transforms. The increased water turbidity resulting from the snow and ice melting leads to the formation of stunning patterns, with swirls of blue and purple blending together in a hypnotic display.
