The unidentified arrowhead shaped plateau appears to be the Holy Grail researchers that have been looking.
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. The discovery was made by Maxwell, Dale Romero and Jimmy Church, host of FADE to BLACK on the Dark Matter Radio Network on Monday, May 12th 2014 and announced on Facebook, Twitter and Church’s radio program the following day. source
The support pillars to the entrance are over 600 feet tall. Malibu, California, is known the world over for its scenic beauty and as the playground of the rich and famous. Few people know that it is also the land of UFOs.
