The Carboniferous

Carboniferous means "coal-bearing" from the Latin root, carbo. During this period Earth experienced glaciation and low sea levels. Organic matter was laid down and would later become coal beds.

A pirate radio station is installed somewhere in the bowels of Cockatoo Island, broadcasting acoustic translations of carbon spectra. Using the enclosed Ground-Penetrating Radio Receiver, your task is to find the signal and decipher its code. You might just learn the coordinates of Gondwanaland’s largest, untapped coal bed.
