Sycamore Knoll
Open conclusionDocumented seabed formation, artificial-structure interpretation unverified
An older Google Earth view showed a broad, flat-topped seabed formation off Malibu. The image is documented, but does not establish an artificial structure or undersea base.
Updated
The file now distinguishes Sycamore Knoll from the Guadalupe Island location discussed by Danny Sheehan.
What is still missing
Full-resolution source bathymetry, independent sonar survey, agreed coordinates and physical material from the site.
