This is the second edition of the antimimeticisomorphism series…
When a thick lava flow cools it contracts vertically but cracks perpendicular to its directional flow with remarkable geometric regularity – in most cases forming a regular grid of remarkable hexagonal extrusions that almost appear to be made by man. One of the most famous such examples is the Giant’s Causeway on the coast of Ireland (shown above) though the largest and most widely recognized would be Devil’s Tower in Wyoming. Basalt also forms different but equally fascinating ways when eruptions are exposed to air or water.

I wasn’t overly convinced by the “moving rocks” in your first example of nature’s antimimeticisomorphistic behaviour (the skeptical side of me showed its colours) but I’m flabergasted by this example!
Why hexagons? I’ve studied civil engineering too, like you, (although I now practice construction law) and geology has always fascinated me, but this!…. this is amazing!!!
