LocationsTOP SECRET SERIES—PART 26: Mysteries, Mountains, and Gateways (Patterns, Portals, and 3, 6, 9 — Part 2) Posted on April 10, 2021 by Administrator Mountains—and, in particular, volcanoes—have long been associated with portals. The Superstitious Mountains, covered in another section of this series, are but one example. The Cascade Range in the western United States is another. Mount Shasta, a stratovolcano, is one of Cascade’s mighty peaks, rising over fourteen thousand feet above sea level. Writer and adventurer Frederick Oliver wrote a book about the “sacred mountain” in 1884, claiming that beneath Shasta’s heights lay a massive network of tunnels and hallways where the descendants of Atlantis lived.
