The bull snake had apparently fallen from the top of the canyon.
Bull snakes often exceed six feet in length and are harmless. We have many bull snakes in Arizona.
They are good to have around if you live in a ranch or in the desert because they go after rodents.
They are often confused by people for rattlesnakes and are unnecessarily killed. Part of the reason that bull snakes are confused as rattlers is that when they are threatened they go into a defensive posture of impersonating a rattlesnake. They will hiss, flare their face into a more triangular flattened shape, and they will take their tail and vibrate it against the bushes, trees or rocks to make a sound.
Rattlesnakes will elevate their tails to make a rattle sound; whereas, the bull snake will keep their tail down to make contact with bushes, trees or rocks to make the sound.
Bull snakes also seem to have an immunity to rattlesnake venom so they are being studied further for their antibodies.
Tomorrow we continue the photography tour into the slot canyons for some fabulous photos.
