California is everywhere and everywhere is California

Via Sullivan and Edge of the American West, here's a wonderful 1927 map of California produced by Paramount Studios, suggesting filming locations throughout the state that looked convincingly enough like other parts of the world.

I'm sorry to see that, at least as of 1927, the studios weren't yet pushing the versatile Topanga Canyon Malibu Creek State Park as a shooting location.  It would later serve as Korea in "M*A*S*H," both Africa and Virginia in "Roots," and (spoiler alert) future Earth in "Planet of the Apes."  Topanga Canyon Malibu Creek State Park is the Meryl Streep of filming locations.
