“I hear the most beautiful sound in the world,” says Dr. Bruce Means. Referring to the call of a toad that he and his expedition team – North Face Climber Mark Synnott and NationalGeographic contributing photographer Joe Riis – travelled to the tops of the Tepuis of South America to find. Means has a hypothesis that he calls a paradigm and this little toad is the missing link. Braving the elements and first time repels into crevices will they find the illusive pebble toad. The expedition was made possible by National Geographic Expeditions Council.
