Washed Away

A foothill palo verde with its roots exposed in a wash at Lost Dog Wash in McDowell Sonoran Preserve

As you hike through the desert you’ll sometimes cross a wash, an area that is normally dry but where water runs after a storm. I’ve not seen a wash run, it doesn’t take long for the water to stop flowing and the monsoons usually arrive in the evenings when I’m not on the trails due to the heat. I’ve seen the aftermath though in the scouring of the trails, I wonder if the roots of this foothill palo verde were recently exposed due to erosion after a summer storm. Most of the shallow roots have been stripped of earth and are angled downstream save for one still plugged into the surviving bank.

It may not look like it but this little tree has leafed out, the trees have tiny leaves that you can see along the thorns if you look at the top of the tree set against the darker green of the larger trees behind it. You can also see the green bark, the palo verde can photosynthesize its food from both the little leaves when they are present and from the green bark and thorns year round. I’m curious to see if it survives or if it will fade away now that its roots are exposed, and perhaps wash away in a future storm. But for now it is holding on, literally.

Rib Cage

Supporting the massive weight of a saguaro is a circular skeleton of woody ribs that sometimes remains standing after the cactus dies. I photographed this lovely example in the soft light before sunrise near the start of the Chuckwagon Trail in McDowell Sonoran Preserve. Hiking the Chuckwagon to the Watershed Trail and up to the Cholla Mountain Loop Trail to see The Amphitheater and Cathedral Rock has become one of my favorite desert hikes, although I’ll mix it up with the Latigo, Vaquero, and Maverick trails too.

I Have Departed and I Will Remain

Most of the branches have broken off this long-dead tree but still it reaches for the sky. In life it wouldn’t have approached the heights of the massive saguaros that dominate the landscape but it would have provided welcome shade for young plants trying to gain a foothold in the desert. In death it can provide some shade and shelter, every little bit helps as while the hills and vegetation behind me are providing some protection from the sun at this early hour, as the sun rises there will be little escaping its glare. Yet life flourishes in this desert, it is not the emptiness of sand and rock I imagined in my youth.

Seeing Red in the Desert

Fruit begins to ripen atop a saguaro on the Vaquero Trail in McDowell Sonoran Preserve in Scottsdale, Arizona

I knew even before setting foot in Arizona that my pictures in the desert would draw heavily from a palette of browns rather than the green of the Pacific Northwest. I didn’t know that there would occasionally b red in the desert too, such as the red racer, the house finch, and the northern cardinal. However, for a month or so at the end of spring and the start of summer red explodes across the desert in the fruit of the saguaro.

Here near The Amphitheater in McDowell Sonoran Preserve a ripe fruit bursts open, exposing the pulp and seeds inside. The fruit is chockfull of seeds, according to the National Park Service there are about 2000 seeds per fruit. Few will develop into a seedling and fewer into an adult saguaro in the harsh desert climate but its not for lack of trying. I noticed multiple birds eating the fruit but mostly it was white-winged doves, who apparently digest the seeds rather than passing them in their waste like some other birds. They end up with so much juice and pulp and seeds on their faces that I imagine some of the seeds will fall to the ground as they preen, so perhaps all is not lost.

As the fruit continues to ripen on the saguaro, even the outside turns red. The dried stalk above them is all that remains of the flowers that grew atop them, the ripened fruit results from flowers that were pollinated. Most of the fruit grows at the top of the saguaro or the ends of its arms but some grows on the sides like the one below that has been cleaned of most of its contents by the denizens of the desert, only a few of the tiny black seeds remain inside.

Do Not Adjust Your Sets

The early morning light falls on one of my favorite saguaros, I love its wavy pattern and look for it whenever I’m hiking Brown’s Ranch Road. If you’re too young to understand the reference in the title and never experienced adjusting horizontal and vertical hold on a television, consider yourself lucky. In my day …

Disappearing Act

This ocotillo had just started leafing out in the middle of July with the arrival of summer thunderstorms in the Sonoran Desert. The white-winged dove perched in the morning light is one of thousands I have seen, they are not only the bird I see most in our backyard but out in the desert as well, never more so when seemingly one or two or three were atop every saguaro as they devoured the ripening fruit. But after a self-imposed two week ban to allow a knee to heal, I returned to the trails twice last weekend and didn’t see a single one. Not one!

From what I’ve read, the white-wings arrived in the desert about the time I did and will be leaving this fall. So I suppose in a month or so they will be gone from our backyard as well. The smaller mourning doves and much smaller Inca doves will appreciate it, the larger white-wings are more aggressive, but our cats and I will miss them.
