Investigator Linda Moulton Howe (earthfiles.com(1)) appeared in the first hour of Wednesday's program, reporting on a set of unusual megalithic stones found off the coast of Cuba that resembled architecture. They "can't be explained in natural geology," said Linda, who listed such shapes as triangles, pyramids and curved surfaces as showing up in the sonar images.
Linda interviewed Paul Weinzweig, co-owner of Advanced Digital Communications International, who was involved in the deep ocean bottom discovery. He told her that National Geographic had expressed interest in a preliminary survey of the structures before they would commit to a more extensive examination.
