9. Indian Cave Petroglyphs
In Harrison County, West Virginia, a small cave was explored in the 19th century. Inside this cave are a number of incredible prehistoric petroglyphs. These petroglyphs portray a number of animals, including rattlesnakes and fish. Indian Cave is unique for its incredibly preserved state and has been described by archaeologists as “virtually unchanged.” Its petroglyphs are unique for their curious use of the color red, which can be seen on a number of the figures.
Archaeologists have determined the petroglyphs to be the work of early Native Americans but cannot identify which culture. Pottery found within the cave suggests that it was occupied sometime between AD 500 and 1675. Similar to other petroglyphs, the motivation for their creation is unclear.
