This is a photo at Big Bend NP at sunrise. At the far left, you can see a formation called the Mule Ears. Why mule ears? It looks as much like many other animals. Personally, I see owl ears.
Mules were used for transporting supplies in the early 1900s in the area. So it makes sense that a mule would be the animal that came to mind.
For me a reminder, look for God in the familiar.
