USA - November 9th, 2010

The southern shores of Lake Michigan are lined by teal sediments, while the rest of the lake, particularly the eastern shoreline, appears navy blue and mostly sediment free. The southern tip of the lake is heavily industrialized.

The only North American Great Lake located entirely within the United States, Lake Michigan is bounded, from west to east, by the states of Wisconsin, Illinois, Indiana, and Michigan.

Lake Michigan is one of the five Great Lakes of North America, and the only one located entirely within the United States. It is bounded, from west to east, by the U.S. states of Wisconsin, Illinois, Indiana, and Michigan. Although this image focuses on the southern section of the lake, parts of all four states are visible. The city of Chicago is also situated on the southwestern shores.

The beaches of the lake’s western coast and the northernmost part of the east coast are rocky, while the southern and eastern beaches are sandy and dune-covered. This is partly because of the prevailing winds from the west which also cause thick layers of ice to build up on the eastern shore in winter. Here, ice can be observed along the southeastern coastline, while greenish sediments or algae border both the western and eastern shores.

The Laurentian Great Lakes are a chain of freshwater lakes located in eastern North America, on the Canada – United States border. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario (from left to right), they form the largest group of freshwater lakes on Earth.

The lakes are bound by the Canadian province of Ontario and the U.S. states of Minnesota, Wisconsin, Michigan, Illinois, New York, Indiana, Ohio, and Pennsylvania. Four of the five lakes form part of the Canada-United States border; the fifth, Lake Michigan, is contained entirely within the United States.

The Saint Lawrence River, which marks the same international border for a portion of its course, is the primary outlet of these interconnected lakes, and flows through Quebec and past the Gaspé Peninsula to the northern Atlantic Ocean.

These images were captured in early spring, after warmer temperatures had thawed much of the ice that frequently covers the lakes in winter. However, as can be observed in the close-ups, a patch of ice is still visible at the northernmost tip of Lake Erie, and in the marshy areas along the northern shores of Lake Huron.

Lake Erie has a substantial amont of greenish-yellow sediments clouding its waters from shore to shore. Lake Huron and Lake Michigan also have some sediments, though these are limited to their southern coastlines.
