Sediments in Lakes Huron, Erie and St. Clair, USA and Canada42.3N 83W
Sediments are present in the North American Great Lakes, turning their waters various shades of blue and green. Lake Huron (above) shows some bluish sediments along the southeastern coast and greenish sediments in a bay to the west, but the central parts of the lake are deeper and dark blue.
All of the visible waters of Lake Erie (below), on the other hand, are clouded by green and tan sediments, as are those of the smaller Lake St. Clair (between Erie and Huron). The city of Detroit, Michigan, USA, can be seen west of the lake.
