I want to know the answer to the following question:
who thought the great plains were the locations of Quivira and Cíbola?
All the background I'm provided with is that "With the arrival of Francisco Vázquez de Coronado, a Spanish conquistador, the first recorded history of encounter between Europeans and Native Americans in the Great Plains occurred in Texas, Kansas and Nebraska from 1540-1542.". Is that enough to answer the question?
