Massive Underwater Entrance Discovered Off The California Coast

A massive underwater entrance has been discovered off the Malibu, CA coast at Point Dume which appears to be the Holy Grail of UFO/USO researchers that have been looking for it over the last 40 years. The plateau structure is 1.35 miles x 2.45 miles wide, 6.66 miles from land and the entrance between the support pillars is 2745 feet wide and 630 feet tall. It also has what looks like a total nuclear bomb proof ceiling that is 500 feet thick. source
