The (Canyon) Walls Have Eyes

During college, my husband and I made frequent backpacking trips to Big Bend National Park with our friends. On one trip, we hiked along an intermittent stream that ran through a small canyon. As I looked at the interesting rock layers of the canyon wall, I saw an eye looking back at me. It belonged to a sleepy little canyon tree frog whose colors perfectly matched those of the rocks. The frog was snuggled into its cool, damp, dark crevice hideaway to escape the heat of the day. Since canyon tree frogs are only 2 ¼ inches long, we were fortunate to see this one hidden among the rocks. After taking its photo, we left the frog in peace to resume its nap until nightfall.
