Valley Region of the Appalachian Mountains and Subsequent Karst Regions in the State of Virginia
This map which appears on page 402 of Process Geomorphology (1995), written by Dale
F. Ritter, Craig R. Kochel, and Jerry R. Miller, serves as the basis of my report on the
formation of the Appalachian Mountains and its subsequent karst regions in along the
Atlantic side of the United States particularly in the state of Virginia. The shaded areas
represent generalized karst regions throughout the United States.
The state of Virginia is divided into five major physiological regions based on
similar landscapes and relatively static climates, each region being as diverse as the next.
From the east to west they are respectively named, the Tidewater which stretches from
the Atlantic Ocean to the fall line, the Piedmont which lies east of the Blue Ridge
Mountains, the Blue Ridge Mountains which exclusively extends to the eastern
Appalachian Mountains, and finally the Ridge and Valley region of the Appalachian
Mountain chain. In this paper I will pay particular attention to the formation of the
Appalachian Mountains and the subsequent karst regions in the western part of the state.
“Ordovician mountain
building events in eastern North
America are collectively termed
Tactonic Orogeny (Stanley,
318).” In short, there were three
such orogenic events that helped
form the current-day
Appalachian Mountains. This was the first of three orogenic episodes occurred when
Laurentia, the North American craton, part of the continental crust, collided with the
Iapetus which is composed of oceanic crust. The resulting impact caused mountains to
rise up in the east. Over thousands of years, through the process of physical and chemi...

The Shenandoah Valley is located in the western part of Virginia. The valley lies between the Allegheny Mountains, Shenandoah Mountains and the Blue Ridge Mountains with the Potomac River being the northern boundary to the valley. The Valley offered two tactical advantages to the Confederates with the Union having knowledge of this. The first is a Northern Army invading Virginia would be vulnerable to a Confederate flanking attacks pouring through the many winding gaps across the Blue Ridge Mountains. The other is that the Valley offers a sheltered avenue that would allow any Confederate army to head north into Pennsylvania uncontested. The Shenandoah Valley also contains twelve bridges that are of significance to any maneuvering army of the day and the valley is only 25 miles wide. The valley represented to the Army of the Potomac (Union) a direct approach to the CSA capital of Richmond, Virginia during the Civil War (Keeg...

In order to define the music of Appalachia, one must first define the area in which the Appalachians encompass. This mountainous area extends 1500 miles and covers an area that extends from Maine to Georgia. There are eighteen states which make up the Appalachians. According to most Europeans, they consider the Appalachians to be only the southeastern region of the United Stated. However, the Appalachians are actually a combined combination of states that include all eighteen states. During the 1920’s these areas were considered 1“Back Country” areas.
...the only major geologic event in the history of the Appalachians. Several glaciers have covered parts of the Northern Appalachians over the last three million years. (Appalachian tales) The mountains have been there ever since and that is how they were formed.

Introduction The Chesapeake Bay is a large estuary located on the east coast of the United States. The bay is over 200 miles long and goes through Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia. The bay has much to offer the locals. Many locals have made a career out of harvesting the bay's sea food.
