Lake Superior depth map (nautical chart)

The map shows the depth and marine chart of Lake Superior, which is located in North America on the border of the USA and Canada. The nautical chart shows the deepest places and helps to pave the route to the desired places for fishing or navigation. Lake Superior is the deepest of the five Great Lakes.

The average depth is 483 ft (147 m), the maximum is 1,333 ft (406 m). The coastline is severely indented. There are several large bays. The southern shores are predominantly sandy and low-lying; the northern shores are characterized by a high altitude (up to 400 m) and a rocky relief. The main effluent goes to Lake Huron, across the St. Marys River.

The northern shore of Lake Superior (at the end of the 16th and beginning of the 17th centuries) was the site of a temporary settlement of the Ojibwe Indians.
