The Allegheny Mountain Range, informally the Alleghenies, is part of the vast Appalachian Mountain Range of the Eastern United States and Canada and posed a significant barrier to land travel in less developed eras. The Allegheny Mountains have a northeast–southwest orientation, running for about 300 miles (480 km) from north-central Pennsylvania, southward through western Maryland and eastern West Virginia.
The Monongahela National Forest is a national forest located in the Allegheny Mountains of eastern West Virginia, USA. It protects over 921,000 acres of federally managed land within a 1,700,000 acres proclamation boundary that includes much of the Potomac Highlands Region and portions of 10 counties.
The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, eastern West Virginia, and western Virginia. The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau to its west. The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.
The Dolly Sods Wilderness is a U.S. Wilderness Area in the Allegheny Mountains of eastern West Virginia and is part of the Monongahela National Forest of the U.S. Forest Service.
The Northern California coastal forests are a temperate coniferous forests ecoregion of coastal Northern California and southwestern Oregon.
The Potomac Highlands of West Virginia centers on five West Virginian counties in the upper Potomac River watershed in the western portion of the state's Eastern Panhandle, bordering Maryland and Virginia. Because of geographical proximity, similar topography and landscapes, and shared culture and history, the Potomac Highlands region also includes Pocahontas, Randolph, and Tucker counties, even though they are in the Monongahela River or New River watersheds and not that of the Potomac River.
Mount Porte Crayon is a mountain in the Roaring Plains Wilderness of the Monongahela National Forest in the northeastern corner of Randolph County, West Virginia, USA. It rises to an elevation of 4,770 feet (1,450 m), the elevational climax of the Allegheny Front. The mountain is named for 19th century writer and illustrator David Hunter Strother (1816–88), known as "Porte Crayon", who produced a wide array of early West Virginia landscapes in his work.
The Appalachian mixed mesophytic forests is an ecoregion of the temperate broadleaf and mixed forests biome, as defined by the World Wildlife Fund. It consists of mesophytic plants west of the Appalachian Mountains in the Southeastern United States.
The Appalachian–Blue Ridge forests are an ecoregion in the Temperate broadleaf and mixed forests Biome, in the Eastern United States. The ecoregion is located in the central and southern Appalachian Mountains, including the Ridge-and-Valley Appalachians and the Blue Ridge Mountains. It covers an area of about 61,500 square miles (159,000 km2) in: northeast Alabama and Georgia, northwest South Carolina, eastern Tennessee, western North Carolina, Virginia, Maryland, and central West Virginia and Pennsylvania; and small extensions into Kentucky, New Jersey, and New York.
Ice Mountain is a mountain ridge and algific talus slope that is part of a 149-acre (60 ha) preserve near the community of North River Mills in Hampshire County, West Virginia, United States. It was designated a National Natural Landmark in 2012.
North Fork Mountain is a quartzite-capped mountain ridge in the Ridge and Valley physiographic province of the Allegheny Mountains, also known as the High Alleghenies or Potomac Highlands, of eastern West Virginia. Kile Knob, at 4,588 feet, is the mountain's highest point, and Panther Knob and Pike Knob are nearly as high.
The Silurian Tuscarora Formation — also known as Tuscarora Sandstone or Tuscarora Quartzite — is a mapped bedrock unit in Pennsylvania, Maryland, West Virginia, and Virginia, US.
Woody's Knob, at an elevation of 4,170 feet, is a summit or "knob" in the Blue Ridge Mountains and one of the highest points in the unincorporated village of Little Switzerland and in Mitchell County, North Carolina.
The Pennsylvanian Pottsville Formation is a mapped bedrock unit in Pennsylvania, western Maryland, West Virginia, Ohio, and Alabama. It is a major ridge-former in the Ridge-and-Valley Appalachians of the eastern United States. The Pottsville Formation is conspicuous at many sites along the Allegheny Front, the eastern escarpment of the Allegheny or Appalachian Plateau.
The Coast Range ecoregion is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in the U.S. states of Washington, Oregon, and California. It stretches along the Pacific Coast from the tip of the Olympic Peninsula in the north to the San Francisco Bay in the south, including Grays Harbor, Willapa Bay, and the Long Beach Peninsula in Washington, the entire length of the Oregon Coast, and the Northern California Coast. Named for the Coast Range mountains, it encompasses the lower elevations of the Olympic Mountains, the Oregon Coast Range, the Californian North Coast Ranges, and surrounding lowlands.
Laurel Hill, also known as Laurel Ridge or Laurel Mountain, is a 70-mile-long (110 km) mountain that is located in Pennsylvania's Allegheny Mountains. This ridge is flanked by Negro Mountain to its east and Chestnut Ridge to its west. The mountain is home to six state parks: Laurel Ridge State Park, Laurel Mountain State Park, Linn Run State Park, Kooser State Park, Laurel Hill State Park, and Ohiopyle State Park. The 70-mile-long (110 km) Laurel Highlands Hiking Trail runs the length of the ridge.
The Roaring Plains West Wilderness is a U.S. Wilderness Area in the Allegheny Mountains of eastern West Virginia, USA. It is part of the Monongahela National Forest and includes Mount Porte Crayon, the sixth highest point in the state.
Spruce Mountain, located in eastern West Virginia, is the highest ridge of the Allegheny Mountains. The whale-backed ridge extends for only 16 miles (26 km) from northeast to southwest, but several of its peaks exceed 4,500 feet (1,400 m) in elevation. The summit, Spruce Knob, is the highest Allegheny Mountain point both in the state and the entire range, which spans four states.
The Laurel Fork is a 15.7-mile-long (25.3 km) stream in Virginia and West Virginia, United States. The stream flows north from Highland County, Virginia, where its source and the majority of its length is located, to its mouth in Pendleton County, West Virginia. Laurel Fork is a tributary to the North Fork South Branch Potomac River, making it a part of the Potomac River watershed. The area surrounding Laurel Fork is home to several plant and animal species found nowhere else in Virginia, and is a prime example of a northern boreal forest in the state.
Appalachian bogs are boreal or hemiboreal ecosystems, which occur in many places in the Appalachian Mountains, particularly the Allegheny and Blue Ridge subranges. Though popularly called bogs, many of them are technically fens.
