Life and death in Saguaro National Park

Behold a fishhook barrel cactus (Ferocactus wislizenii) in the eastern sector of Tucson’s Saguaro National Park as we saw it two years ago today:

Hardy as desert plants are, they all eventually meet their demise. Here’s what a barrel cactus look like then:

Oh, all right, it was Saguaro National Park, so I guess I’ll have to show you a saguaro cactus (Carnegiea gigantea). This one had two particularly enfolding “arms”:

And here are the stately remains of a saguaro with upraised “arms”:

Cholla cactus near sundown

How about this backlit cholla cactus in Tucson Mountain Park near sundown two years ago today?

Sunset Crater Volcano National Monument

Two years ago today we stopped at Arizona’s Sunset Crater Volcano National Monument, which we’d never heard of it till we were in the area.

The oozing, highly textured trunk of an aspen tree (Populus tremuloides) caught my attention there.

Two views of the Grand Canyon

Here are two pictures of the Grand Canyon, one for each of the years since our visit on this date in 2016.

Arizona sycamore

While visiting Montezuma Castle on October 18th last year I learned that there’s such a thing as an Arizona sycamore tree, Platanus wrightii. Like the better-known American sycamore, Platanus occidentalis, this one has bark that peels to reveal trunk and branches that shine white in the light of the sun, especially from a distance. A closer look, like the one below, reveals patterns and details.

From the cliffs of Montezuma

Let’s get two things straight about Montezuma Castle: Montezuma, the Aztec emperor, had nothing to do with it, and it’s not a castle. No, this cliff in northern Arizona shelters the 600-year-old remains of a cliff dwelling created by a people called the Sinagua. And let’s get a third thing straight: that wasn’t their name. No, Sinagua was a name created in 1939 from the Spanish words sin ‘without’ and agua ‘water,’ based on the scarcity of flowing water in the region.

The prominent plants in the foreground are four-wing saltbushes, Atriplex canescens. Here’s a closer look at some saltbushes bordering the parking lot:

Another look at the Grand Canyon

Here’s a look back from October 19th of last year at trees on the rim of the Grand Canyon. In harsh climates, dead limbs often adjoin living ones.
