How Could Lava Form Such Caves? - a photo on Flickriver

Last updated on Dec. 20, 2018
Above photo shows prehistoric artificial cave in American Aleutian Islands in the Pacific. If these columns had been formed by cracks in cooling lava, the columns should have fallen/broken during earthquakes long ago. The columns may have been held together by artificial cement. "Many of the columns (in the Giant's Causeway) fit together so closely that it is impossible to insert a knife blade between them. When viewed from above, the causeway looks like a man made street." (quoted from point 5 in primaryfacts.com/2517/giants-causeway-facts/)
The sea cavern in the Pacific was not formed by nature. The cave's roof and walls were made by prehistoric human beings with concrete columns. See proof in www.flickr.com/photos/fossil_lin/16775178946/in/album-721...
