Underwater Alien Base Near Saipan, April 28, 2014, UFO Sighting News.

Hey guys, was looking over Google Earth and came across this remarkable looking underwater anomaly. The massive walls seem to go for about 50 miles, but long ways is about 250 miles. Sure these anomalies could be an ancient Asian civilization that sank under the ocean long ago, but it also could be an underwater alien base. Its size and location would insure millions could use it and since its in such a secluded area, few humans will ever see their UFOs leaving/entering the water. SCW Feel free to us
