Grand Theft Auto: San Andreas
The rock's formation resembles a phallus, with the two boulders at the base acting as testicles, and the tall, tapering rock representing the shaft and head of the penis itself, easily earning it the name Cock Rock. It is easily seen from the airstrip and in the high rock formations of El Castillo del Diablo and Arco del Oeste. It is an obscene Easter egg placed in the game purposely by Rockstar.
Grand Theft Auto: Chinatown Wars
While not obvious at first due to Chinatown Wars' top-down perspective, its representation of the male genitalia is one of a horizontal profile rather than a vertical protrusion. Shrubs dotting the northeastern outline of the formation act as pubic hair. The rock does not appear in Grand Theft Auto IV, but there is a more natural-looking formation in its place.
