Description: Typical timber rattlesnakes measure anywhere from 36-58 inches (91-147 cm) in length with Klauber (1956) reporting the largest timber rattlesnake ever recorded to be 74  inches (189.23 cm) collected near New Orleans, LA in the 1940s. Timber rattlesnakes are the 2nd largest venomous snake found in the eastern United States.
3) This snake is unlikely to be 24 feet long. It is a lot closer to the camera than the back-hoe so our perception of size is skewed. My guess is the snake is 10-12 feet long. Still a big snake. 4) Bladen County, North Carolina isn't exactly ground-zero for giant rattlesnakes. The world's largest species of rattlesnake (up to about eight feet long), the Eastern Diamond-back Rattlesnake (Crotalus adamanteus), is known from North Carolina (see range map); historically they occurred in the coastal regions.
