Tafoni

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.

Probably the best-known sandstone formations at Nevada’s Valley of Fire State Park are the ones that people have nicknamed beehives. Here’s an example from our visit on October 24, 2016. Notice how one set of compact rock layers slices across many thicker layers.

Sometimes nature suggests human activity when there has been none.

Sometimes nature suggests human activity even where there has been none. As soon as I saw these natural patterns at the Valley of Fire State Park in Nevada on October 24th they reminded me of the petroglyphs you looked at last time.

Thanks to three commenters on that previous post, I now know that the darker markings on the stone shown here are likely to be desert varnish. The areas that tend toward black would have more manganese in them, and the reddish areas more iron. Live and learn.

What’s that on the flat rock?

As intriguing as the rocks themselves are at the Valley of Fire State Park in Nevada, when we visited on October 24th we found that some of them also offer up traces of human activity from bygone ages. Click the excerpt below for a much-magnified look at the details on the flat rock.

I wonder whether the ancient inhabitants darkened the surface of this rock so they could scrape it away to create those orange glyphs.

Not just reddish-orange

The reddish-orange sandstone so common at Valley of Fire State Park in Nevada serves as an excellent substrate for lichens of contrasting colors, as you see in these two photographs from our October 24th visit. You can click either picture to get greater size and more details.
