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.
Fort Ancient is a name for a Native American culture that flourished from c. 1000–1750 CE and predominantly inhabited land near the Ohio River valley in the areas of modern-day southern Ohio, northern Kentucky, southeastern Indiana and western West Virginia. Although a contemporary of the Mississippian culture, they are often considered a "sister culture" and distinguished from the Mississippian culture. While far from agreed upon, there is evidence to suggest that the Fort Ancient Culture were not the direct descendants of the Hopewellian Culture. It is suspected that the Fort Ancient Culture introduced maize agriculture to Ohio. The Fort Ancient Culture were most likely the builders of the Great Serpent Mound. Recent archeological study and carbon dating suggests that Alligator Mound in Granville also dates to the Fort Ancient era, rather than the assumed Hopewell era. It is believed that neither the Serpent or Alligator Mounds are burial locations, but rather served as ceremonial effigy sites.
The Jeffers Petroglyphs site is an outcrop in southwestern Minnesota with pre-contact Native American petroglyphs. The petroglyphs are pecked into rock of the Red Rock Ridge, a 23-mile (37 km)-long Sioux quartzite outcrop that extends from Watonwan County, Minnesota to Brown County, Minnesota. The exposed surface is approximately 150 by 650 feet and surrounded by virgin prairie. "The site lies in an area inhabited in the early historic period by the Dakota Indians, and both the style and form of some of the carvings are identical with motifs that appear on Dakota hide paintings and their quill designs and beadwork. Others are foreign to this Plains Indian tradition and seem to be much earlier in origin." Several old wagon trail ruts traverse the site, one of which is believed to be the old stage coach route from New Ulm, Minnesota to Sioux Falls, South Dakota.

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.
