Volcanic Plug

[Colorado CJ]

Taken somewhere along the Arizona/Utah border.

These volcanic plugs are neat features, popping up all around the four corners area. They really look ancient in person and make you think of how much this landscape has changed.

Interesting formation. The purple in the sky looks very unatural - although the colors in the rock show no perceptible cast.

Nice - my favorite resource for figuring out what the volcanic events were and when they were formed in Utah is a book published by the Utah Museum of Natural History called "The Geology of Utah" by W.L. Stokes. I always carry a copy when I am wandering around in Utah.

This is a very neat image with lots of potential if you can figure out the purple, including the fringe around the rock.

Alan, thanks for the book tip.

They are striking structures. That one looks like Agathla Peak, aka El Capitan, along the road between Kayenta and Monument Valley!

Hey Andrew,

Yeah, I love those plugs! Of course Shiprock is the Granddaddy of them all, but there are many more that look just as cool.
