A secret base of Cronus in the USA. The entrance was hidden in a mesa, but deep underground lay one of the few remaining Relics on Earth; the Relic however was already dead and in a fossiled state. About 400 years ago, it was entrusted by Archanfel to the personal care of Hamilcar Barcas, who had the base constructed.
The base self-destructed in a nuclear explosion after a large attack on it by the Zeus' Thunderbolts; all that remained was an enormous crater.
