A most Unusual Sight

Days 4, 5 & 6 of my road trip were spent at Devil's Postpile National Monument. I happened across it quite by accident, as my original destination was Yosemite. But, as I was not on a schedule, I figured I'd stop by and see what it was all about.

What an amazing sight! The Postpile is made up of thousands of basalt columns formed by an even cooling of lava over 400' deep. The formation occured less than 100,000 years ago, and only 10,000 years ago, a huge glacier eroded away one side of the Postpile, exposing the columns. It also sheared off the tops of the columns, evening and polishing the surface.

Why are the columns 6-sided? Same reason as in a bees nest. A 6-sided object has the most structural strength and stability in nature.

For those of you on the tour, the bus to Yosemite is now boarding! Come along with us!

    Interesting pages, Penny. That squirrel looks dangerous... just kidding, but now a hungry bear is another matter entirely! You sure are brave, travelgirl. ~Elaine~

    Reminds me of the many basalt lava formations in Wells Gray Park, and Lone Butte in B.C.
