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.
Western diamondback rattlesnakes are abundant at Cedar Hill State Park. The second largest measured western diamond back rattlesnake is a 92 inch specimen captured in Cedar Hill, Texas in 1949. However there is a report of another specimen beat the Cedar Hill record by only half an inch. unfortunately there are no known voucher specimens to verify either claim.
