I’m traveling far from home for a month or so, during which time there’ll understandably be only sporadic posts. You’re welcome to comment but it might take me a while to reply.

Here’s a look back at some of the famous red rocks of Sedona (Arizona) as we saw them on October 20th last year.

Skull rock again

with 11 comments

For some unknown reason the e-mail version of the Skull Rock post didn’t go out this morning, so I resent the post and succeeded the second time.

A popular formation at Joshua Tree National Park is Skull Rock. This photograph from November 5th, 2016, shows you the pareidolic reason the boulder is called what it is.

Tafoni

with 10 comments

rock-with-tafoni-4038

From my big Southwest tour I learned the geological term tafoni, a plural noun that refers to “small, rounded, smooth-edged openings in a rock surface, most often found in arid or semi-arid deserts. They can occur in clusters looking much like a sponge and are nearly always on a vertical or inclined face protected from surface runoff.” Such formations have also been called “honeycomb weathering” and “swiss-cheese rock.” The example above is from Arizona’s Wupatki National Monument on October 21st of last year.

The formation shown below from Nevada’s Valley of Fire State Park on October 24th represents a different sort of tafoni that you can imagine inspiring the practitioners of Art Nouveau.

To learn more about tafoni and see many more instances, check out Kuriositas or Wikipedia.

At California’s Muir Beach on November 1st of last year the white veins in some of the rocks intrigued me.

Wupatki National Monument

Continuing north in Arizona from Sunset Crater on October 21, 2016, we soon came to Wupatki National Monument, which we, like most people, visited for its Indian ruins. As a photographer, I appreciated the place for its desert landscapes as well.

On a horizontal rock surface at the site I found a feature that could pass as the inspiration for Rorschach inkblots. What does it say of me if I see this as the fossil of a spiny fish? Chime in if you’d like to say how you see it.
