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.
