Alibates Flint Quarries National Monument is a decades-old archeological site in Texas, located 30 miles northeast of Amarillo, close to Borger, Texas. Alibates Flint Quarries National Monument was first established in 1965 and was later redesigned in 1978. The monument now occupies an area of 1,371 acres.
For centuries, people used to visit the red bluffs above the Canadian River for flint, which they needed to build their tools and weapons. Lucky for them, Alibates Flint was the best you could get. It started 12,000 years ago, when the natives of the Clovis Complex used to extract the rich in color and veined Alibates. They continued to extract flint until 1870. At the monument, you’ll also come across many ruined dwellings of the Plains Village Indians, who used to be residents of the area from 1150 to 1500 BC.
Most of the quarry pits are located on hills, directly above the Canadian River, and providing a very splendid view. Some of these pits are as small as only five feet across, others are as wide as twenty-five feet across. Their depth varies from four to seven feet.
The most in-demand flint in the area is the rainbow-hued flint of superior quality. There are a total of 250 shallow pits at the monument. Most of the vegetation here includes short prairie grasses.
