Rock Snake Hills
From Tardis Wiki, the free Doctor Who reference
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!)
