West Virginia is a U.S. state located in the Appalachian region of the Southern United States. It is bordered by Virginia to the southeast, Kentucky to the southwest, Ohio to the northwest, Pennsylvania to the north, and Maryland to the northeast.
Located in the Appalachian Mountain range, West Virginia covers an area of 24,229.76 square miles (62,754.8 km2), with 24,077.73 square miles (62,361.0 km2) of land and 152.03 square miles (393.8 km2) of water, making it the 41st-largest state in the United States. West Virginia borders Pennsylvania and Maryland in the northeast, Virginia in the southeast, Ohio in the northwest, and Kentucky in the southwest. Its longest border is with Virginia at 381 miles, followed by Ohio at 243 miles, Maryland 174 miles, Pennsylvania 118 miles and Kentucky at 79 miles.
West Virginia is located entirely within the Appalachian Region, and the state is almost entirely mountainous, giving reason to the nickname The Mountain State and the motto Montani Semper Liberi ("Mountaineers are always free"). The elevations and ruggedness drop near large rivers like the Ohio River or Shenandoah River. About 75% of the state is within the Cumberland Plateau and Allegheny Plateau regions. Though the relief is not high, the plateau region is extremely rugged in most areas. The average elevation of West Virginia is approximately 1,500 feet (460 m) above sea level, which is the highest of any US state east of the Mississippi River.
On the eastern state line with Virginia, high peaks in the Monongahela National Forest region give rise to an island of colder climate and ecosystems similar to those of northern New England and eastern Canada. The highest point in the state is atop Spruce Knob, at 4,863 ft (1,482 m), and is covered in a boreal forest of dense spruce trees at altitudes above 4,000 feet (1,200 m). Spruce Knob lies within the Monongahela National Forest and is a part of the Spruce Knob-Seneca Rocks National Recreation Area. A total of six wilderness areas can also be found within the forest. Outside the forest to the south, the New River Gorge is a canyon 1,000 feet (300 m) deep, carved by the New River. The National Park Service manages a portion of the gorge and river that has been designated as the New River Gorge National River, one of only 15 rivers in the U.S. with this level of protection.
Most of West Virginia lies within the Appalachian mixed mesophytic forests ecoregion, while the higher elevations along the eastern border and in the panhandle lie within the Appalachian-Blue Ridge forests. The native vegetation for most of the state was originally mixed hardwood forest of oak, chestnut, maple, beech, and white pine, with willow and American sycamore along the state's waterways. Many of the areas are rich in biodiversity and scenic beauty, a fact that is appreciated by native West Virginians, who refer to their home as Almost Heaven (from the song, "Take Me Home, Country Roads" by John Denver). Before the song, it was known as "The Cog State" (Coal, Oil, and Gas) or "The Mountain State".
The underlying rock strata are sandstone, shale, bituminous coal beds, and limestone laid down in a near-shore environment from sediments derived from mountains to the east, in a shallow inland sea on the west. Some beds illustrate a coastal swamp environment, some river delta, some shallow water. Sea level rose and fell many times during the Mississippian and Pennsylvanian eras, giving a variety of rock strata. The Appalachian Mountains are some of the oldest on earth, having formed over 300 million years ago.
