GIO (Geological Investigation Outpost) is a mining outpost owned and operated by Shubin Interstellar on Baker IV, United Empire of Earth (UEE). GIO mostly consists of a vast network of interconnected mining tunnels deep underground, marked on the planet's surface by a group of utilitarian buildings. In 2945, Shubin held the Shubin Mine Rescue Challenge in GIO, an event in which participants competed to win prizes in categories such as angle vertical rescue, firefighting, and zero-G accident rescue.
