Another stop is a non "car view" scenic spot, "Blowhole Fountain Cave". It's a map of several Hawaiian islands on the ground outside the scenic spot. The Lann Island above is the one that Oracle's owner bought before. of course, the islands are now located in a place that has undergone tens of billions of years of erosion to this point, and there will be submarine volcanoes coming up in the future. Blowhole Fountain Cave, a coastal cave formed by volcanic lava, is also known as Blackstone Fountain. Because of long-term sea erosion, as long as there is sea water influx, it will spray 16 meters high water column spray into the air, accompanied by rumbling sound, which is very shocking. Of course, when we brush the camera in front of it, it becomes very lady, only a few wisps of smoke (water vapor) come out.
