A rainy day at the site of the 1736 silver discovery known as Planchas de Plata, about fifteen miles northwest of the original Arizona Ranch
The State of Arizona takes its name from a ranch started by
Bernardo de Urrea sometime between 1734 and 1736. The general area around his ranch was also known as
Arizona. He and a majority of the first explorers, settlers, and miners in the area were Basque and it is they who probably gave the Basque name
Arizona (the good oak) to the region. Oak trees are abundant both at the original ranch and the entire area between present-day Nogales, Arizona and Saric, Sonora. Bernardo de Urrea's
Arizona Ranch lies about 40 miles southwest of Tumacácori in what is today Sonora, Mexico.
