The first recorded non-indigenous person to see the San Joaquin River was Don Pedro Fages in 1772. Fages, accompanied by Father Juan Crespí, reached Mount Diablo near Suisun Bay on March 30 and there gazed upon the merging courses of the Sacramento, San Joaquin and Mokelumne Rivers. Another narrative does not mention Fages' name, but does say that Crespí was the one who reached Suisun Bay in 1772. During this visit, Crespí called the San Joaquin River "El Rio de San Francisco", a name that was not used widely due to the river's remoteness but persisted until the early 19th century.
