 By the 1850s, there were some Basque sheepherders working in Cahuenga Valley (today Los Angeles, California).In the 1870s, the Los Angeles and Inland Empire land rush reportedly attracted thousands of Basques from Spain, Mexico and Latin America, but such reports do not bear out in a current census of Basque persons in the Southern United States where Basque persons are exceptionally rare in US census reporting.By the 1880s Basque immigration had spread up into Oregon, Utah, Montana, Wyoming, with significantly lesser numbers reaching the Southern states of Arizona, New Mexico, and Texas in the Southern most region.
