Among the most technologically advanced Pre-Colombian Native American cultures were the Morozi Eskimos.

While most tribes in the region were living in igloos and developing the snowshoe, the Morozi had already invented the ice car, seen here behind one of the priests. Depicted here in ceremonial robes and a distinctive ritual cap, Priests were the only caste allowed to drive.

The Morozi were completely killed off for food during the Great Depression, when stockbrokers of New York emigrated to the north and resorted to cannibalism. Thus the secrets of the ice car were lost forever. If not for this mass genocide we may be a far more advanced civilization today, as it was rumored to run on cold fusion, which still eludes the scientists of today.
