A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs, estimated to be 20,000 years old are classified as protected monuments and have been added to the tentative list of UNESCO's World Heritage Sites. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix petro-, from πέτρα petra meaning "stone", and γλύφω glýphō meaning "carve", and was originally coined in French as pétroglyphe.
The Youghiogheny River, or the Yough for short, is a 134-mile-long (216 km) tributary of the Monongahela River in West Virginia, Maryland, and Pennsylvania. It drains an area on the west side of the Allegheny Mountains northward into Pennsylvania, providing a small watershed in extreme western Maryland into the tributaries of the Mississippi River. Youghiogheny is a Lenape word meaning "a stream flowing in a contrary direction".
The Fort Ancient culture is a Native American archaeological culture that dates back to c. 1000–1750 CE. Members of the culture lived along the Ohio River valley, in an area running from modern-day Ohio and western West Virginia through to northern Kentucky and parts of southeastern Indiana. A contemporary of the neighboring Mississippian culture, Fort Ancient is considered to be a separate "sister culture". Mitochondrial DNA evidence collected from the area suggests that the Fort Ancient culture did not directly descend from the older Hopewell Culture.
In archaeology, rock art is human-made markings placed on natural surfaces, typically vertical stone surfaces. A high proportion of surviving historic and prehistoric rock art is found in caves or partly enclosed rock shelters; this type also may be called cave art or parietal art. A global phenomenon, rock art is found in many culturally diverse regions of the world. It has been produced in many contexts throughout human history. In terms of technique, the four main groups are:
Redstone Old Fort — or Redstone Fort or Fort Burd — on the Nemacolin Trail, was the name of the French and Indian War-era wooden fort built in 1759 by Pennsylvania militia colonel James Burd to guard the ancient Indian trail's river ford on a mound overlooking the eastern shore of the Monongahela River in what is now Fayette County, Pennsylvania, near, or on the banks of Dunlap's Creek at the confluence. The site is unlikely to be the same as an earlier fort the French document as Hangard dated to 1754 and which was confusedly, likely located on the nearby stream called Redstone Creek. Red sandstones predominate the deposited rock column of the entire region.
The Monongahela culture were an Iroquoian Native American cultural manifestation of Late Woodland peoples from AD 1050 to 1635 in present-day Western Pennsylvania, western Maryland, eastern Ohio, and West Virginia. The culture was named by Mary Butler in 1939 for the Monongahela River, whose valley contains the majority of this culture's sites.

The Prehistory of West Virginia spans ancient times until the arrival of Europeans in the early 17th century. Hunters ventured into West Virginia's mountain valleys and made temporary camp villages since the Archaic period in the Americas. Many ancient human-made earthen mounds from various mound builder cultures survive, especially in the areas of Moundsville, South Charleston, and Romney. The artifacts uncovered in these areas give evidence of a village society with a tribal trade system culture that included limited cold worked copper. As of 2009, over 12,500 archaeological sites have been documented in West Virginia.

Lake Monongahela was a proglacial lake in western Pennsylvania, West Virginia, and Ohio. It formed during the Pre-Illinoian ice epoch when the retreat of the ice sheet northwards blocked the drainage of these valleys to the north. The lake formed south of the ice front continued to rise until it was able to breach a low divide near New Martinsville, West Virginia. The overflow was the beginning of the process which created the modern Ohio River valley.
