Erased from the pages of time, these cultures discovered and charted the heavens, developed earth-centric sciences and unleashed advancements that parallel and, in many cases, surpass our own.

Drawing inspiration from Charles Hapgood’s controversial crustal displacement theory, the author explores how shifts in Earth’s crust—not just plate tectonics or Milankovitch cycles—might explain glacial cycles, mass extinctions, and unexplained archaeological site alignments. Through detailed analysis of ancient site orientations, climate data, and geological processes, the book proposes a revised mechanism for pole shifts involving an interplay between mantle convection and tidal forces, the same forces that move Earth’s oceans. The work challenges mainstream geoscience and climate models, offering a bold, alternative view of Earth’s deep history and the cycles of civilization, catastrophe, and climate change. Mark Carlotto has over forty years of experience in space-related applications involving remote sensing, mapping, image processing, pattern recognition, machine learning, and related technologies. He received a Ph.D. in Electrical Engineering from Carnegie-Mellon University in 1981 and has written over one hundred technical and scientific papers and nine books. He was an assistant adjunct professor at Boston University from 1981 to 1983 where he taught courses in computer architecture and image processing.Outside of his occupation in the aerospace industry, Dr. Carlotto’s journey as an independent scientist began in 1985 when he first learned of the infamous Face on Mars in a newspaper article. His first book The Martian Enigmas examines the Face and other unusual objects on the Red Planet first imaged by a Viking orbiter spacecraft in 1976.
