The Great Lakes. View from the International Space Station (ISS) of the Great Lakes of the USA and Canada. North is towards upper right. Here, the ISS is over a point to the southeast of Nova Scotia. Sunglint is seen on Lake Ontario (lower right) and Lake Huron (upper right). Lake Erie is at upper left. Much of central Canada (across top) is obscured by extensive cloud cover, whereas a smaller grouping of clouds obscures the Appalachian mountains and Pennsylvania (lower left) in the USA. The thin blue envelope (haze) of Earth's atmosphere is visible above the curved limb across top. Photographed by an Expedition 31 crew member on 14 June 2012.
