Ridge-and-valley Appalachians
The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian Highlands division. The physiographic province is divided into three sections: the Hudson Valley, the Central, and the Tennessee. The river valleys were areas of indigenous settlements for thousands of years. In the historic period, the Cherokee people had towns along many of the rivers in western South Carolina and North Carolina, as well as on the western side of the Appalachian Mountains in present-day Tennessee. Similarly, the Catawba people occupied areas along the upper Catawba River in Western North Carolina, to the east of Cherokee County. The ridge and valley system presents an important obstacle to east–west land travel even with today's technology. It was a nearly insurmountable barrier to European-American migrants who walked or rode horses traveling west to settle the Ohio Country, and ...

Valley And Ridge With Other Provinces Of Appalachian Highlands
A valley is an elongated low area often running between Hill, hills or Mountain, mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that m ...

Forbes Road
The Forbes Road, a historic military roadway in what was then British America, was initially completed in 1758 from Carlisle, Pennsylvania, to the French Fort Duquesne at the junction of the Allegheny and Monongahela rivers in what is now downtown Pittsburgh, via Fort Loudon, Fort Lyttleton, Fort Bedford and Fort Ligonier. The road, initially about 220 miles long, was named for Brigadier General John Forbes, the commander of the 1758 British-led expedition that built the road during the French and Indian War (also known as the Seven Years' War). The Forbes Road and Braddock's Road were the two main land routes that the British cut west through the wilderness during the war. The task was complicated by the Appalachian Mountains' steep northeast-to-southwest ridges, a generally broken terrain between the ridges, heavy forestation, and numerous swamps and rivers. Though the physical barriers of Braddock's and Forbes Roads seem mundane compared to later roads through the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Walden Ridge
Walden Ridge (or Walden's Ridge) is a mountain ridge and escarpment located in Tennessee in the United States. It marks the eastern edge of the Cumberland Plateau and is generally considered part of it. Walden Ridge is about long, running generally north-south. Its highest point is at Hinch Mountain (near Crossville), which reaches above sea level. Sometimes Walden Ridge is called the Cumberland Escarpment. Geology Sequatchie Valley, a long valley in the Cumberland Plateau, is located just west of the southern part of Walden Ridge. Being part of the Cumberland Plateau, Walden Ridge is also part of the Appalachian Plateau physiographic province. The Sequatchie River runs through the valley. To the east of Walden Ridge are the Ridge-and-valley Appalachians and the Tennessee River. Walden Ridge is significantly higher than the Cumberland Plateau, and its eastern slope, descending over from the plateau to the Tennessee Valley, is steep and escarpment-like. Geologically, Walden R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cumberland Mountains
The Cumberland Mountains are a mountain range in the southeastern section of the Appalachian Mountains. They are located in western Virginia, southwestern West Virginia, the eastern edges of Kentucky, and eastern middle Tennessee, including the Crab Orchard Mountains. Their highest peak, with an elevation of above mean sea level, is High Knob, which is located near Norton, Virginia.

Allegheny Front
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 (locally called the Allegheny 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 River, Ohio/Mississippi River, Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean. The Allegheny Front and the Eastern Continental Divide do not always coincide; for example, the Potomac River, North Branch of the Potomac River begins well west of the Front, at the Fairfax Stone Historical Monument State Park, Fairfax Stone near the southwestern tip of Maryland, about and across the actual divide from ...
