Alibates Flint Quarries National Monument, TX
National Park Service
Hikes are by reservation, involve one mile of walking, an elevation gain of 170' and take two hours. The monument protects a mesa covered in a lithic scatter carpet of flint, so thick you cannot walk without stepping on human generated flakes of Alibates flint. The quarries were dug, by hand, 1,000 years ago. However, gathering of flint from the mesa has been taking place for 13,000 years.
