Yes, Well, the cottonmouth I saw at AK (the park not the lodge) is poisonous so DO be careful.
And all snakes bite if threatened and the bite can get infected easily so even if you know the snake is not poisonous don't get close.
ETA - for anyone who is curious the snake was seen climbing the stairs at the EE viewing area on May 7th about 1:00. It went into the big ornamental rock area just beside the stairs and hid. About 15 other people that day saw the snake.
