"The breathtaking Fingal's Cave in Scotland gives you impression that someone has built it. The perfect hexagonally jointed basalt columns were formed during many years when the hot lava was cracked into perfect hexagonal patterns in a similar way to drying mud cracking as it shrinks, and these cracks gradually extended down into the mass of lava as it cooled and shrank to form the columns, which were subsequently exposed by erosion." -www.mediadump.com
Wow that does look like it was built! What a great find.
