Alibates Flint Quarries
Plains Village, Clovis, 11000 BCE–1500 CE
The banded red, purple and white agatized dolomite of the Alibates outcrop was quarried from Clovis times, when it was carried to the Blackwater Draw kill sites, through the Antelope Creek villages that lived beside it. It is the type locality for one of the most recognisable toolstones of the Plains and the only national monument devoted to a quarry. Artifacts of Alibates material appear across the Great Plains and as far as the Mississippi valley.
