Saint Lawrence River Connecting Lake Ontario and Gulf of Saint Lawrence, Canada45.5N 73.5W
The medium blue body of water on the left side of this image is Lake Ontario, on the border of the USA and Canada. The northeastern tip of Lake Huron can also be seen just below, along the left edge. South of Lake Ontario are several long, thin, parallel lakes known as the Finger Lakes (best observed in the full image) in New York State, USA.
The Saint Lawrence River runs out of the eastern end of Lake Ontario and passes the cities of Montreal and Quebec City on its way to the Gulf of Saint Lawrence (upper right quadrant). There, it can be seen releasing tan sediments into the gulf.
The city of Ottawa can also be observed west of Montreal, on the Ottawa River, one of the Saint Lawrence’s tributaries. The two rivers converge by Montreal.
