When did the Navajo Indians first settle in Utah?

The Navajo Indians are believed to have migrated to the southwestern United States, including parts of Utah, around the late 1400s to early 1500s. They gradually settled in the region, particularly in the Four Corners area, where Utah, Arizona, New Mexico, and Colorado meet. The Navajo culture and way of life developed over centuries as they adapted to the landscape and formed their distinct identity.
