Describe the great pueblo period.

The Pueblo III Period (AD 1150 to AD 1350) was the third period, also called the "Great Pueblo period" when Ancestral Puebloans lived in large cliff-dwelling, multi-storied pueblo, or cliff-side talus house communities. By the end of the period the ancient people of the Four Corners region migrated south into larger, centralized pueblos in central and southern Arizona and New Mexico.

Pueblo III Period is roughly the same as the "Great Pueblo Period" and "Classic Pueblo Period" (AD 1100 to AD 1300).
