Answer:
Francisco Vazquez de Coronado.
Step-by-step explanation:
Francisco Vazquez de Coronado was a Spanish explorer whose most famous achievement was the discovery of parts of the southwestern United States such as the Grand Canyon. Coronado and his men sailed into the Gulf of Mexico in 1540 with the intention of finding the legendary city of Cibola, but the strains of the trip turned out to be greater than expected. Blacks imported as slaves fled, as did some of the Indians who served as guides. Many Spaniards also got tired of traveling and returned back to their homes in New Spain. Coronado continued to search for treasures with a smaller group, but they only found several Pueblo villages of 200 to 400 inhabitants.
