The Soo Locks...

Here are four different webcams offering views of the Soo Locks in Sault Sainte Marie, Michigan, USA.

But, "What," you say, "are these Soo Locks?" The Locks are like an elevator for boats. Lake Superior and the Upper St. Mary's River are higher than the Lower St. Mary's River and Lake Huron. Most of the freighters on the river are bringing iron ore from the mines in Michigan's Upper Peninsula to the big cities along the southern parts of the Great Lakes, such as Chicago and Detroit. Without these "boat elevators," the freighters could not get through.

This first camera is the West approach to the Locks, facing the Upper St. Mary's River. https://webcam.crrel.usace.army.mil/soo/camera1.html

The second camera is the view looking west from the Admin building. You can see the International Bridge to Sault Sainte Marie, Ontario, Canada in the background. https://webcam.crrel.usace.army.mil/soo/camera2.html

The third camera shows the view from the Davis Building. https://webcam.crrel.usace.army.mil/soo/camera3.html

The forth and final camera shows the East view from the Admin building showing the Lower St. Mary's River. https://webcam.crrel.usace.army.mil/soo/camera4.html
