Saint-Jean Lake and Saint Lawrence Estuary, Canada – May 24th, 201147.9N 68.8W
The Saint Lawrence River can be seen here, traversing the Canadian province of Quebec. Sediments drain from the river into the Gulf of Saint Lawrence, one of the largest estuaries in the world.
Another river, the Saguenay River, can be seen draining into the estuary from Saint-Jean Lake, a large, relatively shallow lake in the Laurentian Highlands of south-central Quebec. The lake, which is frozen in this image, covers an area of 1003 km² (387 sq. mi.), and is 63 metres (207 ft) at its deepest point.
Another frozen lake, the ring-shaped Manicouagan Reservoir, can also be observed near the top edge, covering an area of 1,942 km². The lake’s distinct annular shape is because it lies within the remnant of an ancient eroded impact crate.
