USA and Canada - August 15th, 2011

This image focuses on Lake Huron, one of the five Great Lakes of North America, and Georgian Bay (the large bay connected to the lake in the upper part of the image). Sediments can be observed along the southern shores of the lake, although most of the rest of the shoreline of the lake and bay is clear.

Lake Huron is bounded on the east by the Canadian province of Ontario and on the west by the state of Michigan in the United States. It is the second largest of the Great Lakes, with a surface area of 59,596 km2 (23,010 sq mi) making it the third largest fresh water lake on earth. It contains a volume of 3,540 km3 (850 cubic miles), and a shoreline length of 3,827 mi (6,157 km).

Georgian Bay is a large bay of Lake Huron, located in Ontario, Canada. The main body of the bay lies east of the Bruce Peninsula and Manitoulin Island. The Main Channel separates the Bruce Peninsula from Manitoulin Island and connects Georgian Bay to the rest of Lake Huron.

Smoke trails east-northeast from a wildfire burning northwest of the Canadian city of Greater Sudbury, in the province of Ontario, in the upper left quadrant of this image.

Several bodies of water can be seen nearby, the closest of which is Lake Wanapitei, which occupies a meteorite crater near Greater Sudbury. The crater is 5.2 miles (8.37 km) in diameter and the age is estimated to be 37.2 ± 1.2 million years.

East of Lake Wanapitei is the larger Lake Nipissing, with a surface area of 873.3 km2 (337.2 sq mi) and a mean elevation of 196 m (643 ft) above sea level. It is relatively shallow for a large lake, with an average depth of only 4.5 m (14.8 ft). The shallowness of the lake makes for many sandbars along the lake’s irregular coastline.

To the south of both lakes is Georgian Bay, is a large bay of Lake Huron (bottom left quadrant). The main body of the bay lies east of the Bruce Peninsula and south of Manitoulin Island, the largest island in a freshwater lake in the world.  The Main Channel separates the Bruce Peninsula from Manitoulin Island and connects Georgian Bay to the rest of Lake Huron.
