Ice on Lake Superior
Ice floats on the surface of Lake Superior, the largest of the five Great Lakes of North America. As the ice breaks apart, the dark blue waters beneath become visible.
Lake Superior is bounded to the north by Ontario, Canada and Minnesota, United States, and to the south by the U.S. states of Wisconsin and Michigan.
It is the second largest freshwater lake in the world by surface area and is the world’s third-largest freshwater lake by volume.
Lake Superior has a surface area of 31,820 square miles (82,413 km2). It has a maximum length of 350 miles (563 km) and maximum breadth of 160 miles (257 km). Its average depth is 482 feet (147 m) with a maximum depth of 1,332 feet (406 m).
Lake Superior contains 2,900 cubic miles (12,100 km³) of water. In fact, there is enough water in Lake Superior to cover the entire land mass of North and South America with 1 foot (30 cm) of water.
The shoreline of the lake stretches 2,726 miles (4,387 km) (including islands). The lake’s elevation is 600 feet (183 m) above sea level.
Annual storms on Lake Superior regularly record wave heights of over 20 feet (6 m). Waves well over 30 feet (9 m) have been recorded.
