Seneca Rocks is one of the best-known landmarks in West Virginia. These rocks have long been noted as a scenic attraction and are popular with rock climbers. The rocks are a magnificent formation rising nearly 900 feet above the North Fork River. Eastern West Virginia contains many such formations of the white/gray Tuscarora quartzite. Seneca Rocks and nearby Champe Rocks are among the most imposing examples. The quartzite is approximately 250 feet thick and is located primarily on exposed ridges as caprock or exposed crags.
