Anasazi Petroglyphs
Petroglyphs are images incised in rock. They were an important form of pre-writing symbols. These petroglyphs are thought to have been made almost 1,000 years ago.
There are more than 100 ancient Anasazi sites in Monument Valley. The petroglyphs, along with the Anasazi ruins, are mostly located in Mystery Valley in the restricted area.
They were the ancestors of the modern Pueblo people, today about 20 communities living in New Mexico and Arizona. There is extensive literature available about the culture of modern and historic Pueblo people.
There never was an "Anasazi tribe", nor did anyone ever call themselves by that name. Anasazi is originally a Navajo word that archaeologists applied to people who farmed the Four Corners before 1300 AD.
This Navajo word means ancient enemy (or old-time stranger, alien, foreigner, outsider) and is considered an ethnic slur by modern Pueblo peoples, although it has been in common use for about about 70 years.
