Mythical Morrison cave closed over Doors-inspired graffiti

Fans of the band who have marked up a scenic cave on the California coast with psychedelic graffiti will have to find another place to spray out their love for frontman Jim Morrison.

The trend began with a social media myth that the singer wrote songs in Corral Canyon Cave in Malibu Creek State Park.

The problem is the combination of tags and hashtags, with people putting pictures of the "Jim Morrison cave" on Instagram, Twitter and Facebook, though he never wrote a known word there.
