Wow! You are a brave soul. I hate heights. I had enough trouble walking up all the steps and inclines just to get this picture:
Our tour guide warned us against going beyond the safety zones, saying he'd be pretty ticked off if any of us fell, and he had to haul our suitcases all the way over to the cliff to throw them over after us.

So, did folks use those cool basalt rocks to build castles, etc.?

I never saw any castles in Ireland made out of basalt. Most of the castles were granite.

I just wondered since those basalt rocks were so regularly shaped. I wonder if they’d work for masonry?

Way cool
I’ve seen similar formations at Mt Rainier in Washington

Yep. As some pictures noted, Devil's Tower in Wyoming is also columnar basalt. So is Devil's Postpile National Monument. There are also examples in Yellowstone and the Palisades along the Hudson River.

Utterly amazing. They look so regular and symmetrical you would swear they were man made. Thanks for the geology lesson. Great thread.

it contracted in both directions.. however vertical contractions along with gravity just resulted in settling of the lava, where as horizontal contractions caused it to pull apart and crack. thats what i got from wikipedia anyway
