VINCE, No geologist here but those are some interesting rock formations and not at all similar to Hawaii 'rocks".
I assume that 'island' was not formed by volcano activity.
Have any of the major motion picture companies ever used that terraine for any motion pictures we might have seen.
My nephew was involved in some of the major rustic scenes that were shot in New Zealand for those Lord of the Rings films which involved a lot of expensive helicopter flights, but now you can shoot those same scenes cheaply with a pro 'video' camera and a top notch drone.
Have you ever considered shooting 4K videos using a drone for that rustic terraine?
