Which indigenous people are known for their impressive cities built in the desert of the southwestern United States?

The Navajo

The Navajo, one of the most populous indigenous peoples in the United States, have a long history that spans several centuries in the Southwest, particularly in Arizona, Utah, and New Mexico. Known for their art, including weaving and silver jewelry, the Navajo maintain a deep relationship with their environment, which they consider sacred. Monument Valley, with its iconic rock formations, is one of the most symbolic sites of their ancestral territory.
