Wildfire North of Lake Huron in Ontario, Canada46.5N 81W
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.
