The birth canal, as it's called apparently. The entrance/exit to the Corral Canyon Cave, also known as Jim Morrison's Cave in the Santa Monica Mountains.

Still unsure how I feel about it (national park lands being graffitied), but still interesting to see! #SantaMonicaMountains #Malibu #hiking #CaveHunting #CorralCanyonCave #CorralCanyon #JimMorrisonCave #GraffitiCave (at Jim Morrison Cave)
