I was thrilled to find my first round-tail in the desert while hiking not too far from our campground. When I came back to report to my wife and sister, I spooked up another one just a few feet from the campground's edge.
When in doubt, Round-tailed Horned Lizards tend to tuck themselves up and do their best rock impression, as seen in the first two photos here. Even when not in the tucked position, they are remarkably good at being overlooked.
