Rock Snake Hills

The Rock Snake Hills were a series of hills on Mars.

In either June of 2067 (PROSE: Capt. Black Mars Expedition Lost!) or 2087, (PROSE: Rogues Gallery) Black commanded a Zero X expedition to Mars in order to investigate the "strange radio signals" (PROSE: Capt. Black Mars Expedition Lost!,  'Jinx Ship' Blasts Off For Mars) received from the Rock Snake Hills area over the previous year. (PROSE: Capt. Black Mars Expedition Lost!)
