While the Mississippi River winds its way down the left side of this image, a pair of other distinctive bodies of water is visible to the right. These are Kentucky Lake (left) and Lake Barkley (right). The brown land between them is part of the Land Between the Lakes National Recreation Area, in the US states of Kentucky and Tennessee.

The Tennessee and Cumberland Rivers flow very close to each other in the northwestern corner of Middle Tennessee and Western Kentucky, separated by a rather narrow and mostly low ridge.

This area where they are only a few miles apart had been known as “Between the Rivers” since at least the 1830s or 1840s. After the Cumberland River was impounded in the 1960s and a canal was constructed between the two lakes, Land Between the Lakes became the largest inland peninsula in the United States.

Downstream from this area, the courses of the rivers then diverge again, with the result being that the mouth of the Cumberland into the Ohio River is approximately 40 mi (64 km) from that of the Tennessee.

Ridges, Valleys and a Wildfire in the Area of Knoxville, Tennessee, USA

The city of Knoxville in the state of Tennessee, USA, is visible as a greyish circular area in the lower left quadrant, near a series of hills and ridges. These are part of the Appalachian Ridge-and-Valley Province, which consists of a series of elongate and narrow ridges that traverse the upper Tennessee Valley.

Also of note in this image is a wildfire in the upper left quadrant, the smoke from which is blowing northeast. The fire is located in the state of Kentucky, not far from the Tennessee border.

The most substantial Ridge-and-Valley structures in the Knoxville area are Bays Mountain, which runs along the Knox-Blount county line to the south, and Beaver Ridge, which passes through the northern section of the town. The Great Smoky Mountains— a subrange of the Appalachian Mountains— are located approximately 20 miles (32 km) south of Knoxville.

In the southeast part of the city, the French Broad River joins the Holston River to form the Tennessee River. Knoxville is centered around a hilly area along the north bank of the river between its First Creek and Second Creek tributaries.

Two lakes are visible northeast of Knoxville. The first, Douglas Lake, also called Douglas Reservoir, is an artificial lake created by an impoundment of the French Broad River by Douglas Dam. The dam was built by the Tennessee Valley Authority in the early 1940s to control flooding in the Tennessee Valley and provide electricity to rural areas in the region. The lake, easily identified by it’s snakelike bends, is situated only a few miles from the Pigeon Forge/Gatlinburg area and the Great Smoky Mountains National Park.

The second body of water, just north of Douglas Lake, is the Cherokee Reservoir, also known as Cherokee Lake, formed by the impoundment of the Holston River behind Cherokee Dam, which was built for hydroelectric generation and flood control. The reservoir has a surface area of about 28,780 acres (11,650 ha), a flood-storage capacity of 749,406 acre feet (924,379,000 m3), and nearly 400 miles (640 km) of shoreline. In a normal year, the lake water level fluctuates over a range of about 27 feet (8.2 m).

The  Mississippi River, appearing greenish brown, winds its way almost vertically across the left side of this image of the USA. The tan terrain around it is part of the Mississippi River Alluvial Plain, which includes parts of seven states.

Moving eastward, another river is visible in the Tennessee Valley by the Blue Ridge Mountains (part of the greater Appalachian Mountains): the Tennessee River. Here, it appears golden yellow from sediments and sun glint; this coloration makes it easier to observe various reservoirs created by dams along its course.
