The former
Tongva/
Fernandeño (Native American) village in this area was called
Wixánga, which comes from the word
wixár (or "thorn" or "prickle" in English) in the Fernandeño dialect of the
Tongva language. Hence,
Wixánga meant something like "place/canyon of the thorns" in English, in reference to the abundant
prickly pear cacti naturally found in the area. This was later reflected in the
Spanish name for the area, or
Cañada de las Tunas ("canyon of the thorns" in English). Finally, this became La Tuna Canyon, and now Sun Valley. In 1874, California State Senator
Charles Maclay (for whom Maclay Street in
San Fernando is named) acquired 56,000 acres (230 km2) of land across the San Fernando Valley. The area extended from Sunland Blvd. all the way west to the Chatsworth Hills. East of Sunland was
Rancho San Rafael, a large land grant to
José María Verdugo by the Spanish Crown. By 1876, the Southern Pacific Railroad was constructed through the eastern San Fernando Valley, linking Southern and Northern California. A general store named Roberts Store was used as a post office and water-tank station; later the area's name was changed to Roscoe, reportedly after the name of a railroad crew member. In the 1920s, development began on the
Fernangeles tract (a blend of San Fernando and Los Angeles), with movie producer
Cecil B. DeMille among the developers. The current name of Sun Valley was chosen in 1950 by residents. ==Geography==
