Gulf of Mexico Shipwreck In 2001, ExxonMobil was laying pipeline in the Gulf of Mexico when they ran into a shipwreck around 2,600 feet under the surface.Upon exploring the shipwreck, archaeologists believed it to be a terrible spell, as something would constantly go wrong when they went down to explore.
