The Mass Grave is a pit located at the foot of a mesa in El Castillo del Diablo, Bone County, northwest of the Restricted Area, southwest of the Verdant Meadows Airfield and just across the street from Snake Farm in Grand Theft Auto: San Andreas.


The pit, which takes the form of a large round hole, contains six body bags, and a Bobcat truck next to the pit.

It is unknown who the six people in the grave are, as the grave plays no role in the storyline and no explanation is given regarding its origins.
