Great Appalachian Valley
Encyclopedia
The Great Valley, also called the Great Appalachian Valley or Great Valley Region, is one of the major landform features of eastern North America
. It is a gigantic trough — a chain of valley lowlands — and the central feature of the Appalachian Mountain system. The trough stretches about 1200 miles from Quebec to Alabama and has been an important north-south route of travel since prehistoric times.
physiographic province
. There are many regional names of the Great Valley, such as the Shenandoah Valley. From a large perspective the Great Valley can be divided into a northern section and a southern section.
lowlands encompassing the 106 miles (170.6 km) Richelieu River

, then southerly in succession through the Hudson River Valley
, up the Newburgh Valley and Wallkill Valley
to Port Jervis, New York
crossing into the Delaware River
basin in the Kittatinny valley
(at the Delaware Water Gap
), Lehigh Valley

, and reaching the Potomac River
watershed and the northern part of the Cumberland Valley
.
A series of mountains bounds the valley to the east, including, from north to south, the Green Mountains
of Vermont
, the Taconic Mountains
, the Reading Prong
(which includes the Hudson Highlands
), the New York and New Jersey Highlands (including the Kittatinny Mountains
), Schunemunk Mountain
, and the Ramapo Mountains
), and South Mountain
of Pennsylvania
. There is a wide gap between Reading Prong and South Mountain, through which the Susquehanna River
passes, connecting the Great Valley with the Piedmont
region of southeast Pennsylvania. Some sources cite this gap as the dividing point between the northern and southern sections of the Great Valley.
Another series of mountains makes up a more impenetrable series of north-south oriented line of ridges and bounds the valley to the west. These are mainly the first major ridges of the Valley and Ridge Appalachians
and the eastern escarpments of the Allegheny Mountains
and Allegheny Plateau
. They include, from north to south, the Adirondack Mountains
; the Catskill Mountains
(specifically the Helderberg Escarpment
); and a long and nearly continuous mountain ridge with several names—Shawangunk Ridge
, Kittatinny Mountains
, Blue Mountain
—stretching from New York through New Jersey to Pennsylvania. This long mountain continues into Virginia with the name North Mountain
. These mountains on the west side of the Great Valley are broken by the gap of the Mohawk Valley
in New York, which connects the Hudson River Valley with the lowlands south of Lake Ontario
. The long Kittatinny-Blue-North Mountain is broken by a few narrow wind and water gap
s, such as Culver Gap, Delaware Water Gap
, Pennsylvania Wind Gap
, Lehigh River
Gap, Schuylkill River
Gap, Swatara
Gap, the Susquehanna River
Gap, Big Gap, and, farther south, the Potomac River
Gap.
, which extend north into Pennsylvania as South Mountain
. Regional names of the southern Great Valley include Hagerstown Valley
in Maryland
, Winchester Valley and Shenandoah Valley
in Virginia
and West Virginia
, the upper valley of the James River
, Roanoke Valley
, and New River Valley
in Virginia, the Holston River
Valley in Virginia and Tennessee
, and the East Tennessee Valley
extending from Virginia through Tennessee to Alabama
. Some sources describe the Coosa River
Valley as the southernmost part of the Great Valley. These southern portions of the Great Valley are sometimes grouped into two parts, the Valley of Virginia and the Tennessee Valley.
The southern Great Valley is bounded on the east by the Blue Ridge physiographic province, which includes, from north to south, South Mountain
in Pennsylvania, the Blue Ridge of Virginia, Holston Mountain
in Tennessee, and the Unaka Range
and the Great Smoky Mountains
of Tennessee and North Carolina. An important gap in these mountains occurs near Roanoke, Virginia
. Other gaps of note in the Blue Ridge of Virginia, connecting the Piedmont region with the Great Valley include Thornton Gap
, Swift Run Gap
, and Rockfish Gap
.
Another series of mountains bounds the southern Great Valley to the west, including North Mountain
and Great North Mountain
, the Allegheny Front
, Powell Mountain, Cumberland Mountains
, Walden Ridge
, and the Cumberland Plateau
. The Cumberland Gap
connects the Great Valley region with Kentucky
and Tennessee lands to the west.
Massanutten Mountain
lies in the middle of the Valley of Virginia portion of the Great Valley.
The Valley of Virginia is a region of karst
, with many sinkhole
s and cavern
s.
. In pre-colonial and early colonial times a major Indian pathway through the Great Valley was known as the Great Indian Warpath
, Seneca Trail, and various other names.
For white immigrants the Great Valley was a major route for settlement and commerce in the United States along the Great Wagon Road
, which began in Philadelphia. In the Shenandoah Valley the road was known as the Valley Pike
. The Wilderness Road
branched off from the Great Wagon Road at present-day Roanoke, Virginia
, crossed the Cumberland Gap
and led to Kentucky and Tennessee, especially the fertile Bluegrass region
and Nashville Basin
. Another branch at Roanoke, called the Carolina Road, led into the Piedmont
regions of North Carolina
, South Carolina
, and Georgia
.
The various gaps connecting the Great Valley to lands to the east and west have played important roles in American history. On the east side, the wide gap in southeast Pennsylvania became the main route for colonization of the Great Valley. By the 1730s the Pennsylvanian Great Valley west of South Mountain was open to settlement after treaty cessions and purchases from the Indians. The region drew a steady and growing stream of immigrants and became known as "the best poor man's country". Before long immigrants had thoroughly settled the Great Valley in Pennsylvania and were rapidly migrating and settling southwards into the Shenandoah Valley of Virginia. The entire region between southeast Pennsylvania and the Shenandoah Valley soon became famous as a "breadbasket", the most productive mixed farming region in America (Meinig, 1986:134). The road from Philadelphia west to the valley and then south through it became very heavily used and known variously as the Great Wagon Road, the Philadelphia Wagon Road, the Valley Road, etc. The Conestoga wagon
was developed around 1725 in the area of the wide opening between Philadelphia and the Great Valley. The Conestoga wagon became the main vehicle for transportation through the Great Valley until the railroad era.
Culver Gap near Culvers Lake in Sussex County, New Jersey, was an important route through the Kittatinny Mountain from about 10,000 years ago to present. The Gap is more than 400 feet below the top of the mountain. Lenape Native Americans used the gap to hunt and trade on both sides of the mountain. Early settlers from Pennsylvania used the water drop from Culvers Lake to Branchville for a wide assortment of mills. Turnpikes followed the route of Lenape trails through the gap.
By the 1750s the Great Valley was well-settled to the southern end of Shenandoah Valley. Immigrants continued to travel from the Philadelphia area south through the Great Valley beyond Shenandoah, to the vicinity of the modern city of Roanoke, Virginia. There is a wide gap in the Blue Ridge near Roanoke. A branch of the Great Wagon Road began there, crossing through the gap east into the Piedmont region of North Carolina and South Carolina. This road became known as the Carolina Road. During the 1750s the stream of migrants traveling south through the valley and into the Carolina Piedmont grew into a flood. At the time, the Carolina Piedmont region offered some of the best land at the lowest prices. Soon a string of towns appeared, including Salisbury
, Salem
, and Charlotte
in North Carolina. In the decades before the American Revolution
the Piedmont "upcountry" of the Carolinas was quickly settled, mostly by recent immigrants who had migrated from the north to the south via the Great Valley. Many of these immigrants were Scots-Irish, Germans from the Rhineland-Palatinate
area, and Moravians
. This "upcountry" population soon surpassed the older and more established "lowcountry" population near the Atlantic coast, causing serious geopolitical tensions in the Carolinas during the late 18th century (Meinig, 1986: 291–293).
On the west side, the Cumberland Gap became the main route for migration west from the southern Great Valley to Kentucky and Tennessee. In the north, the Mohawk Valley
became a major route for westward expansion, especially after the construction of the Erie Canal
, which linked New York City to the Great Lakes
region via the Hudson River of the Great Valley and the Mohawk Valley gap.
The Great Valley played an important role during the American Civil War
, especially the Shenandoah Valley, its Blue Ridge gaps and nearby Piedmont area, and its northward extension to the vicinity of Gettysburg
. Civil War era sites and events in this region include Harpers Ferry
, Antietam
, Manassas, Virginia
, Chambersburg, Pennsylvania
, the Valley Campaign
, the Valley Campaigns of 1864
, the Battles of Chattanooga
, and the Gettysburg Campaign
.
To the north, I-81 continues past Harrisburg, and along with sections of Interstate 476
, serves most of the Pennsylvanian regions in the Appalachian Valley. It eventually connects to Interstate 84
in Scranton. I-84 crosses the Delaware River near Port Jervis and continues to roughly parallel the northern reaches of the Valley, until its mid-Hudson junction at Newburgh with Interstate 87
, a highway which spends the rest of its length closely tracing the Hudson River and Lake Champlain valleys to the north. I-87 becomes Autoroute 15 at the Canadian border and continues to follow the Richelieu River valley north, through southern Quebec
to the Montreal area.

The various gaps connecting the Great Valley to lands to the east and west have played important roles in American history. On the east side, the wide gap in southeast Pennsylvania became the main route for colonization of the Great Valley. By the 1730s the Pennsylvanian Great Valley west of South Mountain was open to settlement after treaty cessions and purchases from the Indians. The region drew a steady and growing stream of immigrants and became known as "the best poor man's country". Before long immigrants had thoroughly settled the Great Valley in Pennsylvania and were rapidly migrating and settling southwards into the Shenandoah Valley of Virginia. The entire region between southeast Pennsylvania and the Shenandoah Valley soon became famous as a "breadbasket", the most productive mixed farming region in America (Meinig, 1986:134). The road from Philadelphia west to the valley and then south through it became very heavily used and known variously as the Great Wagon Road, the Philadelphia Wagon Road, the Valley Road, etc. The Conestoga wagon

was developed around 1725 in the area of the wide opening between Philadelphia and the Great Valley. The Conestoga wagon became the main vehicle for transportation through the Great Valley until the railroad era.
Culver Gap near Culvers Lake in Sussex County, New Jersey, was an important route through the Kittatinny Mountain from about 10,000 years ago to present. The Gap is more than 400 feet below the top of the mountain. Lenape Native Americans used the gap to hunt and trade on both sides of the mountain. Early settlers from Pennsylvania used the water drop from Culvers Lake to Branchville for a wide assortment of mills. Turnpikes followed the route of Lenape trails through the gap.
By the 1750s the Great Valley was well-settled to the southern end of Shenandoah Valley. Immigrants continued to travel from the Philadelphia area south through the Great Valley beyond Shenandoah, to the vicinity of the modern city of Roanoke, Virginia. There is a wide gap in the Blue Ridge near Roanoke. A branch of the Great Wagon Road began there, crossing through the gap east into the Piedmont region of North Carolina and South Carolina. This road became known as the Carolina Road. During the 1750s the stream of migrants traveling south through the valley and into the Carolina Piedmont grew into a flood. At the time, the Carolina Piedmont region offered some of the best land at the lowest prices. Soon a string of towns appeared, including Salisbury
