フランシスコ・バスケス・デ・コロナド
The area was named by the conquistador Francisco Vásquez de Coronado. His expedition of 1540 camped at the confluence of the two major arroyos (Escondido and the Aduana) of present-day Álamos and made reference to local geographical landmarks, including two large rock formations on Mount Alamos known as Los Frailes, 'the monks' in English.
