In depth copperhead identification, very useful for many areas. Thank you for sharing. In Arizona the snakes are not user friendly and like you said, most will try to move away from people. A lot of venomous bites come from people scaling rocky cliffs and they are bit on the hands. Out of view and startled the snake has the advantage. Pulling yourself up a rocky ledge only to find being eye to eye with a coiled rattler is a sobering experience. Always use caution when out exploring in the Arizona desert.
