Alibates Flint Quarries

About Alibates Flint Quarries

Alibates Flint Quarries National Monument preserves ancient quarries where Native Americans mined high-quality flint for over 13,000 years. The colorful Alibates flint was prized for making tools and weapons and was traded across much of North America. The monument protects both the geological formations and the archaeological evidence of prehistoric quarrying activities. Managed by the National Park Service, access is only available through guided tours to protect the fragile archaeological resources.
