Next to snakes, frogs and other amphibians are some of the coolest creatures on the planet. They are cooler than most people in my opinion. Frogs are also thought to be good indicators of environmental conditions because they cannot tolerate very much pollution in the water. Leopard frogs are very common in the southern United States, but not all that common in the north.
These leopard frogs were found in a crystal-clear pool at about 7,000 feet elevation. The water was so cold that my hands went numb in just seconds when reaching for frogs.
