In some of the shallows the spring-run bottom was blackened by Black Toad Tadpoles
On the way eastward we again spiraled our way upward (stopping at just under 11,000 feet!) to see the forests of the ancient Bristlecone Pines. Some of these twisted yet stately trees are more than 4,000 years old. They survive, in fact thrive only, at altitudes and temperatures unsuitable for most other trees and mammals, but are visited (at least in summer) by Clark’;s nutcrackers, a raucous raven and jay relative.

Photos taken, we then descended to a less ear-popping elevation to look up Black Toads, Bufo exsul, a protected species. The BLM access to the spring fed flat on which the narrow spring run that was home to this population of toads, was rocky and uncomfortable. But along it we saw a Northern Desert Horned Lizard, Phrynosoma platyrhinos calidiarum and some beautiful cactus blossoms.

The black toad, a species that is active both diurnally and nocturnally, is aptly named, being black dorsally with varied marblings of white and gray and a white vertebral line. Ventrally the color is white with extensive and varied black smudging. Adults are rather small, often being a mere 2 to 2 ½” in length. We did see a few of the adults as well as hundreds of metamorphs and what seemed thousands of tadpoles. Unfortunately occasional flooding carries toads and tadpoles onto the not too distant salt flat where they quickly succumb. As untenable as this may sound, this population of the Black Toad has probably existed under these conditions for centuries. It was formally described in 1942.

The breeding call, seldom heard, is a high pitched repetitive “trill” that is best described as a rapid-chuckle. After photos were made we moved onward.
