Kansas marks the endpoint of Coronado's expedition. The Spanish conquistador led an extensive exploration from 1540 to 1542, searching for the legendary Seven Cities of Cibola. After traversing present-day Arizona, New Mexico, and Texas, the expedition ventured into Kansas, where they encountered the Great Plains and its vast expanse. Despite their extensive travels, Coronado's expedition ultimately failed to locate the fabled cities of gold and silver.
