Like most predators, snakes aren't interested in confronting humans unless they absolutely have to. They're just trying to hunt and survive, much like we may be when we encounter them. However, snakes are also masters of disguise, so hikers and campers often inadvertently surprise these animals. The resulting snakebite can result in serious injury or death.

It's generally wise to avoid snakes altogether in the backcountry, but there are circumstances when that might not be possible. You may come across one in your campsite, or you may be desperate for food — if you're able to safely kill and cook a snake, it can provide much-needed protein and energy during a survival situation. No matter the circumstance, it's helpful to know what sort of snake you're dealing with.
