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.
