What makes the gray fox, Urocyon cinereoargenteus, stand out from other canine species? Its ability to climb trees! Gray foxes have been spotted in Red Rock Canyon not only on the ground near rocky terrain and shrubs, but also resting high up in trees. These creatures feast on a mixed diet of fruits, small mammals, and invertebrates and are primarily active during the evenings. Gray foxes are about the size of a small to medium dog. Try looking within the Willow Springs area to spot one of these creatures during dawn & dusk hours.
