If you go east in the Delta Rio Wanay region which is in the northeast area of Solis Island, you'll find a derelict structure that resembles the velociraptor enclosure in the film "Jurassic Park". You can even find a cow in the enclosure on occasion which is a reference to what they were fed. If you turn the power on and interact with the control console, you'll hear someone say "Ah, ah, ah. That's not the magic word." This is a reference to Dennis Nedry's virus 'Whte_rbt.obj' which locked his computer when Ray Arnold tried to access it.
