Arizona / Planchas de Plata
"Toward the end of last October, between the Guevavi Mission and the ranchería called Arizona, some balls and slabs of silver were discovered, one of which weighed more than one hundred arrobas (2,500 pounds), a sample of which I am sending to you, Most Illustrious Lord." Captain Juan Bautista de Anza to Bishop Benito Crespo, January 7, 1737.

"I say that Your Honor having ordered me to go impound the silver that was located in the place called Arizona, and Agua Caliente, from that which was found and discovered in the place called San Antonio, it has been done according to your instructions to me." Bernardo de Urrea to Juan Bautista de Anza, January 8, 1737.

Prospecters and miners rushed to the area of the great silver discovery of October,1736. It was given the name San Antonio de Padua by Justicia Mayor Juan Bautista de Anza when he arrived on the scene in November and ordered that all the silver that had been taken from the site be impounded and brought to Urrea's Arizona Ranch, some fifteen miles down the canyon. Because his escribano (scribe), Manuel José de Sosa, dated all the impounding documents at Arizona, people in faraway places like Guadalajara and Mexico City were soon referring to the silver as the "silver of Arizona." Thus, Arizona quickly became a household word associated with great and sudden wealth. Contrary to popular myth, however, the silver, or the area, were never referred to as Arizonac, even though both Arizona and Arizonac are viable Basque words. Arizona is simply singular (the good oak tree) and Arizonac is plural (the good oak trees).
"They found a piece of silver of 120 arrobas close to Arizona, a small village in the Pimería Alta." Father Bernardo Middendorf, Aus dem Tagebuche de mexicanischen Missiorarius, 1765.
Long before Arizona became associated with the United States of America, the area just south of the present international border at Nogales, and a particular ranching community within that area, was known as Arizona. The earliest known records of a place called Arizona date back to the spring of 1736.
