The Greenbrier River in Marlinton

The Greenbrier River is a tributary of the New River, 173 miles (278 km) long,[4] in southeastern West Virginia, in the United States. Via the New, Kanawha and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 1,656 square miles (4,290 km2).[4] It is one of the longest rivers in West Virginia.[6]

Course[edit]

The Greenbrier is formed at Durbin in northern Pocahontas County by the confluence of the East Fork Greenbrier River[2] and the West Fork Greenbrier River,[1] both of which are short streams rising at elevations exceeding 3,300 feet (1,000 m) and flowing for their entire lengths in northern Pocahontas County.[4][7] From Durbin the Greenbrier flows generally south-southwest through Pocahontas, Greenbrier and Summers Counties, past several communities including Cass, Marlinton, Hillsboro, Ronceverte, Fort Spring, Alderson, and Hinton, where it flows into the New River.[7]

History[edit]

Along most of its course, the Greenbrier accommodated the celebrated Indian warpath known as the Seneca Trail (Great Indian Warpath). From the vicinity of present-day White Sulphur Springs the Trail followed Anthony’s Creek down to the Greenbrier near the present Pocahontas-Greenbrier County line. It then ascended the River to the vicinity of Hillsboro and Droop Mountain and made its way through present Pocahontas County by way of future Marlinton, Indian Draft Run, and Edray.

Uses[edit]

The Greenbrier is the longest untamed (unblocked) river left in the Eastern United States.[8] It is heavily used for recreational pursuits.[4] Its upper reaches flow through the Monongahela National Forest,[7] and it is paralleled for 77 miles (124 km) by the Greenbrier River Trail, a rail trail which runs between the communities of Cass and North Caldwell.[9]

It has always been a valuable water route, with the majority of the important cities in the watershed being established riverports. The river gives the receiving waters of the New River an estimated 30% of its water volume. Over three-fourths of the watershed is an extensive karstic (cavern system), which supports fine trout fishing, cave exploration and recreation. Many important festivals and public events are held along the river throughout the watershed.

In honor of the river's use in the state's logging history, the West Virginia State Park, Cass Scenic Railroad in Cass has a car called "The Greenbrier River."[1]

Variant names[edit]

Geology[edit]

Caves and karst[edit]

The unique karstlands of the Greenbrier River Valley — underlain by the Greenbrier Limestone Formation — constitute one of the world's densest sinkhole plains, with an average of 18 sinkholes per square kilometer. This green "moonscape" of collapsed craters is a unique problem for development as the ground is prone to subsidization. It is impossible to tell how large a cave system is by looking at the surface, and developers often build their structures too close to the open spaces beneath the ground. There is no current karst protection plan for any of the counties that are involved with this problem.[citation needed]

The aggregated caves and karst of the Greenbrier River Valley are among the world's Top Ten Endangered Karst Ecosystems as listed by the Karst Waters Institute in 2001.[10]

West Virginia State Fossil[edit]

American vertebrate paleontology arguably began in the sub-watershed of Second Creek, a Greenbrier tributary. Bones discovered by saltpeter miners in Haynes Cave close to the river in Monroe County were sent to (future President) Thomas Jefferson, who identified them as a previously unknown species. Without a skull for identification purposes, Jefferson used the eight-inch claws as an identifying mark, and named the skeleton, Megalonyx or "Great Claw". Later the bones were positively identified as that of a giant ground sloth. The name "jeffersonii" was later added to it in tribute. For years the sloth was mistakenly thought to be from another cave within the watershed, Organ Cave, but recent research indicates that Haynes Cave was the cave of origin. The Megalonyx jeffersonii is now the state fossil of West Virginia.

West Virginia State Gemstone[edit]

The West Virginia state gemstone is also part of the Greenbrier River watershed: The Lithostrotionella, a fossilized form of coral[11] that is found in the Hillsdale Limestone group in Pocahontas and Greenbrier counties. Not an official gemstone, it is a siliceous chalcedony. It is found almost exclusively within Greenbrier and Pocahontas counties.[12]

Ecology[edit]

The Greenbrier hosts one of the state's two endemic species of salamanders, the West Virginia Spring Salamander in Fort Spring. The other salamander, the Cheat Mountain Salamander lives in the mountains of the headwaters.

The Candy Darter of Knapp Creek (Finescale saddled darter) is a survivor to when the Greenbrier followed a more ancient drainage pattern with Teays Valley.

Threats to the Greenbrier[edit]

The river is vulnerable to Nonpoint source pollution and sediment from timbering and flooding. It has been on the WV List of Impaired Streams since 2006 for the contamination of fecal coliform bacteria. Algae is becoming a known nuisance upon the waters, primarily in warm weather, and there is a need to study how much water can be pulled out of the river to supply the needs of communities in a state that practices little in the way of water conservation, even in times of drought. The West Virginia Department of Environmental Protection and various concerned citizen groups are working to prevent further stresses upon the river.

On December 17, 2009 the West Virginia Department of Environmental Protection's James Summers released a report on its findings of algae in West Virginia rivers. The Greenbrier was deemed the most algae-affected river in the state, due to nutrient source tracking. Steps are currently being made to address this issue.[13]

Maps[edit]

The New River Atlas has successfully mapped the Greenbrier from Ronceverte to Hinton, West Virginia.[14] The Atlas shows the original batteau channels and historic man-made impacts.
