Arco, Idaho

The Devil Boat

Supposedly Satanic numbers adorn this preserved submarine sail. 

Located in the city of Arco, ID, the so-called Devil Boat (otherwise called the ‘Submarine in the Desert’) is actually the preserved sail of the submarine USS Hawkbill. The number 666 displayed on the sail was actually the boat’s hull number and, officially, has no connection to the occult. The monument was placed in the roadside Arco park to honor the city’s long association with the Navy and the nuclear fleet in particular.
