Over a decade ago, I visited Giants Causeway in Ireland and I was amazed with the thousands of hexagonal shapes that formed. I was so intrigued that I researched similar areas and found Devils Postpile in Mammoth Lakes, California. The monument features thousands of hexagonal basalt columns formed 100,000 years ago when a lava flow slowed and then cooled and cracked. It immediately went on my bucket list and yesterday I was finally able to cross it off.
Leaving from the village of Mammoth, I took a bus to Devils Postpile National Monument trailhead. The entire hike is only 1 mile but I added other interesting stops a little further down the trail.
When I arrived at the Postpile, I was as impressed with it as I’d hoped. This rare geological wonder is not to be missed. It’s columns stretch 60 feet high and a foot path allowed me to walk to the top to see the hexagonal pattern of unusual symmetry.
It looked like a professional craftsman shaped the columns. It’s hard to believe they were made by nature.
I walked down the other side of the columns and I was awestruck that on this side they jetted out from the cliff sideways.
Even with a detailed explanation of how it happened, I still feel like it’s a wonder that I don’t understand. Seeing it for myself helps but I’m still amazed at Devils Postpile.
If you love unexplainable geological features then I suggest you visit the Moeraki boulders if you ever make it to New Zealand. The spheres appear out of the dune cliff then ‘march’ across the beach until they disintegrate in the waves.

Was it in piles like this? I haven’t heard of other locations in the US. I’d love to look into it more.

Lesley, they are very similar but much shorter. As I understand it, it is the forward edge of a lava flow hitting a large glacier and cooling very quickly. My email address is [email protected]. If you’d like, email me and I will send you the pictures I took from a bike ride up to Sunrise visitor center in Rainier

The hexagon is a very efficient nesting mechanism that appears often in nature. Everything seeks the lowest possible energy state. No wasted space. It can be seen when ground freezes, basically what happened when the basalt at Postpile cooled.

Above is “frost heaving” of stones in tundra. Many of the best examples have to do with ice.
Above are some “ice postpiles” I photographed on the west side of Mt. Whitney.
The regularity of the hexagons depends on the crystallization time.
