The Saint Lawrence river flows from southwest to northeast out of Lake Ontario, forming the border between the Canadian province of Ontario (above) and the US state of New York (below). The river connects the Great Lakes with the Atlantic Ocean and is the primary drainage of the Great Lakes Basin.
Other lakes are visible near Lake Ontario, including the long, thin Finger Lakes (lower right quadrant) in New York State, the rounded Lake Simcoe (center left edge) and the northeastern tip of Lake Huron (bottom left corner). Away from the lakes, in the upper left corner, a wildfire can be seen releasing smoke towards the northwest.
