Twin Sault Ste. Marie Cities on St. Marys River, Canada and USA – October 1st, 201046.5N 84.3W
This images focuses on the area between Lake Superior (upper left quadrant), Lake Michigan (lower left corner), and Lake Huron (lower right quadrant). Lakes Superior and Huron are connected by the St. Marys River.
The river drains Lake Superior, starting at the end of Whitefish Bay and flowing 120 km (74.5 miles) southeast into Lake Huron, with a fall of 23 feet. For its entire length it is an international border, separating Michigan in the United States from Ontario, Canada.
A large grey area can be observed along the river. The part to the north is the city of Sault Ste. Marie, Canada, while the part to the south is the identically named Sault Ste. Marie, USA. The two cities are joined by the International Bridge, which connects Interstate 75 on the Michigan side and Huron Street on the Ontario side.
Shipping traffic in the Great Lakes system bypasses the Saint Mary’s Rapids via the American Soo Locks, the world’s busiest canal in terms of tonnage that passes through it. This record is achieved in spite of the locks being closed during the winter from January through March, when ice shuts down shipping on the Great Lakes. This image was captured in late summer and is therefore ice-free, although sediments can be observed in the rivers and bays.
