Grand Theft Auto: San Andreas
Cock Rock is a rock formation found in GTA: San Andreas, west of Verdant Meadows and south of Las Payasadas in Bone County. It is in the shape of a penis, earning it its name. It is easily seen from the airstrip in Verdant Meadows and from high rock formations like El Castillo del Diablo and Arco del Oeste. Coincidentally there is an uncharted rock formation in Arches National Park east of The Great Wall that resembles a penis.
Grand Theft Auto: Chinatown Wars
A similar rock formation can be found in GTA: Chinatown Wars. However, it is not that noticeable, having a flatter appearance. The GTA: Chinatown Wars rendition is situated on the beach of Firefly Island. The rock is not officially known as Cock Rock, but has gained the term for its penis-like shape.
