Lake Superior's deepest point [4] on the bathymetric map. [1] Lake Superior has a surface area of 31,700 square miles (82,103 km 2), [7] which is approximately the size of South Carolina or Austria. It has a maximum length of 350 statute miles (560 km; 300 nmi) and maximum breadth of 160 statute miles (257 km; 139 nmi). [8]
Jeffrey Val Klump is an American limnologist.He was the first person to reach the deepest spot in Lake Superior, a depth of 1333 feet (733 feet below sea level), the second lowest point in the United States after Iliamna Lake, on July 30, 1985 while aboard the R/V Seward Johnson with the Johnson Sea Link-II submersible.

Therefore, mean depth figures are not available for many deep lakes in remote locations. [9] The average lake on Earth has the mean depth 41.8 meters (137.14 feet) [9] The Caspian Sea ranks much further down the list on mean depth, as it has a large continental shelf (significantly larger than the oceanic basin that contains its greatest depths).
The Grand Sable Dunes today form a five-mile-long sand slope that rises from Lake Superior at a 35° angle. The summits of the tallest dunes are as high as 275 feet (85 m) above lake level. Glacial melt during the last major advance/retreat called the Marquette Readvance created the conditions for the formation of the Grand Sable Banks.
Lake Superior National Marine Conservation Area covers roughly 10,000 km 2 (3,861 sq mi) of lakebed, its overlaying freshwater, and associated shoreline on 60 km 2 (23 sq mi) of islands and mainland. [7] The area is home to numerous species including herons, peregrine falcons, and bald eagles.
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag. The moment reminds his father of Patrick’s graduation from college, and he takes a picture of his son with his cell phone.
First lit in 1849, it was one of the first lighthouses on the shores of Lake Superior. [15] It is the oldest active light on the lake, standing at the point of land that marks the course change for vessels coming from the southern coast of Lake Superior, known as the "Graveyard of the Great Lakes", to the Soo Locks.
