All of these explorers entered present-day Oklahoma except __________.

Friar Marcos de Niza’s 1539 expedition explored areas of present-day Arizona and New Mexico, but did not reach present-day Oklahoma. Coronado and Friar Juan de Padilla traveled into the region during the search for the cities of Cíbola and Quivira, and Juan de Oñate’s expedition also crossed parts of Oklahoma. So the exception is Friar Marcos de Niza.
