I almost walked right past them.
We were walking along Soldier’s Pass Trail in Sedona, Arizona. It was an 80 degree day, and I was focused on what was ahead, not what was to the right or to the left.
Fortunately, a friend of mine noticed the tiny pools off the trail and led us there. These were known as the seven sacred pools.
I had to climb up onto a rock to see the first canyon tree frog – it, along with the others we saw, was just lying on the rock taking in the hot afternoon sun.

Photographing them was fairly easy – they didn’t seem to budge and weren’t frightened of us in the least. One looked straight at me the whole time I was photographing him or her.
It’s odd that they are called tree frogs, given that they are typically found in spots similar to the one where I found them, ie basking on rocks.
