 Although it is generally considered to be a naturally occurring geological feature, as a result of the unusual arrangement and shape of the stones, some believe that the formation is the remains of an ancient road, wall, or some other deliberately constructed feature.For example, articles published in "Argosy" (an American pulp magazine) and either authored or coauthored by Robert F. Marx, a professional diver and visitor to the Bimini Road, argued that the Bimini Road is an artificial structure.In a 1971 "Argosy" article, Robert Marx reported that Carl H. Holm, who was President (not "head geologist" as reported by Marx) of Global Oceanic, once a manager for North American Rockwell, a ship designer; and retired naval officer, stated that there was "little doubt" that the massive stone blocks were cut by people.
