Ephemeral Lake Carnegie, in Western Australia, fills with water only during periods of significant rainfall. In dry years, it is reduced to a muddy marsh.

The Lena River, some 2,800 miles (4,400 km) long, is one of the largest rivers in the world. The Lena Delta Reserve is the most extensive protected wilderness area in Russia. It is an important refuge and breeding ground for many species of Siberian wildlife.

A 150-foot-deep meltwater channel carves its way through the Greenland Ice Sheet, a vivid sign of the glacial melting affecting the vast Arctic island.
Photographer James Balog’s assistant stands above the channel, whose black bottom is composed of cryoconite, made up of silt and soot blown from afar.

Hurricane Sandy After Landfall (October 30, 2012)
Hurricane Sandy made landfall along the southern New Jersey coast on the evening of October 29, 2012, the U.S. National Hurricane Center reported.
As the storm came ashore, it continued to pack strong wings—roughly 85 miles (140 kilometers) per hour. Tide gauges recorded storm-surge heights of 12.4 feet (3.8 meters) at Kings Point, New York.
The Geostationary Operational Environmental Satellite 13 (GOES-13) captured this natural-color image of Hurricane Sandy at 1:45 p.m. Eastern Daylight Time (17:45 Universal Time) on October 28, 2012.
Note how a line of clouds from a continental weather system runs south to north along the Appalachian Mountains, approaching from the west to meet the offshore storm.
