These first people are known as the Basketmakers and they lived in pithouses clustered into small villages usually built on mesa tops but sometimes in the overhangs of the cliffs. These hunter-gatherer people settled and began farming and using the bow and arrow, a weapon that was more efficient and accurate than the atlatl. By 750 AD, the people were building mesa-top villages made of adobe. By the late 12th century they began to build the cliff dwellings for which Mesa Verde is famous.
