Giant Rock, as it is so aptly named, was the key factor in George Van Tassel’s contact with aliens and thus, the building on The Integratron. He had originally learned of the rock from Frank Critzer, who excavated under what was considered the world’s largest single boulder to create a dwelling of several small rooms. Critzer was a resourceful and shrewd man and reckoned since he didn’t have the resources to build a home, digging out a dwelling under the boulder was his best bet. The rock would get cold during the winter to keep it cool during the summer, and then absorb the heat in the summer to warm it during winter. This delayed thermal reaction was proved to be pretty spot on as it never got over 80 degrees in the summer or below 55 in the winter. In the 1950’s Van Tassel acquired the land and the 7 foot tall, 5800 square foot rock and began holding meditation meetings to contact aliens in the room beneath the rock. In August of 1953, a saucer landed from Venus (as the area next to the rock was conveniently ran as an airport landing strip) and invited Van Tassel on the ship, where he learned of cell rejuvenation and time travel. Even despite the UFOs, can you imagine living under a giant boulder? Those guys were crazy!
