USA – November 28th, 2012

Lake Michigan is the only one of the Great Lakes wholly within the borders of the United States; the others are shared with Canada. Twelve million people live along its shores, mainly in the Chicago and Milwaukee metropolitan areas. Here, Chicago appears as a grey area on the southwestern shoreline. Sediments line the southern shores and can be seen by Chicago.

Lake Michigan has a surface area of 22,400 square miles (58,000 km2), making it the largest lake entirely within one country by surface area, and the fifth largest lake in the world.

Although only the southern half is visible here, the lake is 307 miles (494 km) long by 118 miles (190 km) wide with a shoreline 1,640 miles (2,640 km) long. The lake’s average depth is 46 fathoms 3 feet (279 ft; 85 m), while its greatest depth is 153 fathoms 5 feet (923 ft; 281 m). It contains a volume of 1,180 cubic miles (4,918 km³) of water.
