Alibates Flint Quarries National Monument

Alibates Flint Quarries is an archaeological monument in Texas Panhandle with dozens of excavation pits scattered across the site. Indigenous peoples worked these pits over many centuries to extract high-quality flint for making tools and weapons.

Indigenous peoples mined flint here for over 13000 years, making it one of the oldest quarry sites in North America. Tools crafted from this material spread across the Great Plains through trade networks that connected distant communities.

The Antelope Creek people settled here between 1200 and 1450 and made the flint quarries central to their way of life. Their stone structures show how closely they lived with extraction and tool-making.

Visitors can only explore the quarry pits with guided tours led by knowledgeable staff at the site. Wear comfortable shoes and prepare for uneven ground and exposed areas with little shade.

The flint found only here displays distinctive patterns in shades of gray, red, and blue that appear nowhere else in the world. Archaeologists can trace tools discovered across North America back to this location by recognizing these characteristic colors.
