USA – December 13th, 2012

Several fires can be seen in the southern USA (best observed upon opening the full image). In the upper left quadrant, a fire can be seen in the Ouchita Mountains, on the northern shores of Lake Ouchita, in Arkansas. The plume of smoke from this blaze is blowing due north. In the full image, at least five other fires can be seen in and near the mountains, in both Arkansas and Oklahoma.

In the lower half of the image, three fires can be seen between Lake Sam Rayburn (left) and the Toledo Bend Reservoir (right), in eastern Texas, with two other fires visible southeast of the Toledo Bend Reservoir, west and east of the city of DeRidder, Louisiana.

Several fires can be seen in southeastern Oklahoma and southwestern Arkansas, around the Ouachita Mountains. The range itself runs through west central Arkansas and southeastern Oklahoma, although its subterranean roots may extend as far as central Texas (in the full image, the city of Dallas can be seen to the southwest). The Ouachita Mountains form the U.S. Interior Highlands, one of the few major mountainous regions between the Rocky Mountains and the Appalachian Mountains.

The Mississippi River is the chief river of the largest river system in North America. It rises in northern Minnesota and meanders slowly southwards for 2,530 miles (4,070 km) to the Mississippi River Delta at the Gulf of Mexico (bottom). The river either borders or cuts through ten states. Here, it can be seen in Tennessee, Arkansas, Mississippi, and Louisiana. Formed from thick layers of this river’s silt deposits, the Mississippi River Valley is one of the most fertile agricultural regions of the country,

This orthorectified image shows part of the section of the Mississippi River called the Lower Mississippi River. This section runs from its confluence with the Ohio River to its mouth at the Gulf of Mexico. Measured by water volume, the Lower Mississippi’s primary branch is the Ohio River.

The widest point of the Mississippi River is in the Lower Mississippi portion where it exceeds 1 mile (1.6 km) in width in several places. Many rectangular fields can be seen on either side of the river, in the Mississippi River Valley. Formed from thick layers of this river’s silt deposits, the Mississippi River Valley is one of the most fertile agricultural regions of the country.
