While there are at least 20 species of snakes living in the Blue Ridge Mountains, only two of them are venomous. However, both are shy and rarely encountered by humans.
Timber rattlesnakes can grow up to 72 inches in length with thick, heavy bodies. Because of their large size, these rattlesnakes can inject a lot of venom when they bite.
Copperhead snakes are relatively large snakes, measuring 36-48 inches long with copper-red heads and hourglass-shaped patterns on their backs and sides.
