NPS Photo All About Rocks
Alibates Flint Quarries National Monument has been renowned for over 13,000 years due to its valuable flint, a rock whose origins and characteristics are explored in greater detail on the Geology page link below. Historically, local tribes not only quarried this flint but also relied on the diverse regional plant life—such as mesquite trees, soapberry bushes, sages, and cacti—for food, medicine, and tools, a relationship studied through ethnobotany, with more insights available on the Ethnobotany page below. |
