This Landsat image from 9 September 2010 features the Clearwater
Lakes in Canada’s Quebec province. Located to the east of the Hudson
Bay, what appears to be two separate lakes is actually a single body of
water that fills two depressions. The depressions were created by two
meteorite impacts, believed to have hit Earth simultaneously up to 290
million years ago. The name 'Clearwater Lakes' comes from the clarity of
its water.
ESA supports the Landsat series as a Third Party
Mission, meaning it uses its ground infrastructure and expertise to
acquire, process and distribute Landsat data to users.

The larger of the two to the northwest is about 36 km in diameter and
has a ring of islands in the centre. The smaller is about 26 km in
diameter. A string of islands separate the two water-filled craters.
The name 'Clearwater Lakes' comes from the clarity of its water.
The surrounding terrain is dotted with smaller lakes and rivers. The
topography of this area, known as the Canadian Shield, was shaped by the
huge ice sheets and glaciers from the last ice ages covering the area
up to 15 000 years ago.
The Thematic Mapper on Landsat-5 is jointly managed by NASA and the US
Geological Survey. ESA supports the Landsat series as a Third Party
Mission, meaning it uses its ground infrastructure and expertise to
acquire, process and distribute Landsat data to users.
