First of all, the snake is not dead. If it were dead, it would not be "curling". Second, if it were dead, he woud not be holding it that far away from himself. The snake is very much alive and he's being extra careful! Notice the bend in the pole from where he's holding it to where the snake is. BOY'S, I'M HERE TO TELL YOU, IT'S A BIG SNAKE!
The snake is being picked up by a pair of snake tongs that act kind of like a big set of pliers. The tongs barely fit around the snake. I blew this photo up and counted 14 buttons on the snakes tail. Anyone that knows about rattlers knows that buttons always break off towards the back.
The fact that the snake has 14 existing buttons means it's an old snake and it is most certainly approaching if not exceeding the 6 foot mark, and where I come from, that's a big snake. I've taken a few from the Sierra Vista/Fort Huachuca area while I was the game warden there,and yes, they do grow to 6 feet in length.
For a rattle snake to grow that large, there has to be plenty of moisture and rodents around. The largest snakes I retrieved were most always found near or around horse corrals where there was always quite a bit of feed around, thusly a large amount of mice and rats. Lotsa mice and rats=big snakes.
