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.

Flowing upwards from the bottom right, the Weser River empties into the North Sea off the coast of Germany. To its right is another rivermouth, that of the Elbe, and to its left is the Jade Estuary, a bay known as Jadebusen in German.

About 180 km² (70 mi²) in area, the Jade was largely created by storm floods during the twelfth and sixteenth centuries. During this period it was connected in the East to the river Weser. This connection was closed between 1721 and 1725 by dikes reconnecting Butjadingen to the mainland as a peninsula.

The 452 km long Weser River passes by the historic port city of Bremen before emptying into the North Sea 50 km further north at Bremerhaven, which is also a seaport. On the opposite (west) bank is the town of Nordenham at the foot of the Butjadingen Peninsula. It is the longest German river whose course lies entirely in German territory to reach the sea.

Wispy clouds stretch across the central to southern part of Lake Baikal, in Russian Siberia. Framing the southern shore of the lake are the Hamar-Daban Mountains, which stretch for the distance of over 250 km. They receive the greatest amount of precipitation in the whole Baikal region.

Also of note along the shores of the lake is the Selenga Delta, surrounded by greenish waters. The Selenga River has a length of 992 km and carries 935 m³/s of water into Lake Baikal, comprising almost half of riverine inflow. The wide delta it forms has a surface area of 680 km².

South of the delta and the Hamar-Daban Range is Lake Gusinoye, meaning Goose Lake, a body of fresh water in the Russian republic Buryatia. It is located about 120 kilometers from Ulan Ude, the capital of Buryatia, and is close to the border with Mongolia.
