Why were coronado and soto disappointed?

Coronado and Soto were disappointed primarily because their expeditions failed to find the vast riches and prosperous civilizations they had been led to believe existed in the New World. Coronado searched for the fabled Seven Cities of Gold but instead encountered mostly barren lands and small, impoverished Native American settlements. Similarly, Soto's exploration of the southeastern United States yielded little in terms of treasure or resources, leading to frustration and hardship for both explorers and their men. Their experiences highlighted the stark contrast between European expectations and the reality of the American landscape.
