Horned lizards (Phrynosoma) are a genus of lizards which are the type genus of the family Phrynosomatidae. The horned lizard is popularly called a "horned toad", "horny toad", or "horned frog", but it is neither a toad nor a frog. The popular names come from the lizard's rounded body and blunt snout, which make it resemble a toad or frog. (Phrynosoma literally means "toad-bodied".) The spines on its back and sides are made from modified scales, whereas the horns on the heads are true horns (i.e. they have a bony core).
Horned lizards use a wide variety of means to avoid predation. Their coloration generally serves as camouflage. When threatened, their first defense is to remain still to avoid detection. If approached too closely, they generally run in short bursts and stop abruptly to confuse the predator's visual acuity. If this fails, they puff up their bodies to cause them to appear more horned and larger, so more difficult to swallow. At least four species are also able to squirt an aimed stream of blood (see Autohaemorrhaging) from the corners of the eyes for a distance of up to five feet. They do this by restricting the blood flow leaving the head, thereby increasing blood pressure and rupturing tiny vessels around the eyelids. This not only confuses predators, but also the blood tastes foul to canine and feline predators. It appears to have no effect against predatory birds. To avoid being picked up by the head or neck, a horned lizard ducks or elevates its head and orients its cranial horns straight up, or back. If a predator tries to take it by the body, the lizard drives that side of its body down into the ground so the predator cannot easily get its lower jaw underneath the lizard. ~ Wikipedia
The true summit to Aspen Peak involves a climb up a steep boulder where a perch is rather precarious. A few of us did the climb then returned to terra firma for our snack break. Views of Mt. Charleston, Mt. Potosi and Mt. Humphries were blurred by dust, haze and glare but they were there. The weather on the peak was cooled by a nice breeze.
