Coronado International Memorial - August 18, 1941
Coronado National Memorial was established as a unit of the National Park System to commemorate Francisco Vásquez de Coronado's sixteenth-century expedition into what is now the United States. This is the only national park unit commemorating this event. The memorial's southern boundary is on the border between the United States and Mexico and offers extraordinary views of the San Pedro River Valley and an opportunity to delve into the first major exploration of the American Southwest by European explorers.
