Pueblo Jar, also known as an OLLA, is a type of pottery that was traditionally used by the Pueblo people of the American Southwest. It is a rounded, bulbous jar with a wide mouth and a narrow neck, often decorated with geometric designs. OLLA is the Spanish word for 'POT' and is used to refer to this type of pottery. The Pueblo Jar is still used today for ceremonial purposes and for storing food and water.
