Re: Magnificent... with a click

It's Fingal's Cave on the island of Staffa in the Inner Hebrides in Scotland. The gaps are sea caves.


I managed to find a geological summary of the place. The light-colored rock on the bottom is volcanic tuff, which can be very fragile. With the top of that formation right at sea level, cracks would have been widened by surf and storm action, essentially boring a tunnel into the tuff. The basalt columns above are all actually independent, having gaps that can be microscopic in size, often with soluble minerals between that were deposited as the lava cooled and the columns formed. With the tuff foundation eroded, columns above the growing gap would have been without support, and as the minerals between them dissolved they would have subject to shattering from beneath. The top layer of rock is also basalt but is a jumbled layer of "volcanic debris" which since no real columns formed is more cohesive than the columnar formation, so it persists as a cap over the space vacated as columns collapsed.
