Timber rattlesnakes and copperheads. The former species commonly reaches three feet in length, is thick-bodied with patterned markings of brown and black, and usually will buzz when it detects the approach of people. To avoid rattlesnakes, stay on trails and off rocky, warm slopes. Rattlesnakes are rarely found at the highest elevations or during the winter. Copperheads are scarce above 2,500 feet elevation. Rocky hillsides, stone fences, and abandoned buildings are likely places to encounter them. Neither rattlesnakes nor copperheads are aggressive and their presence should not prevent you from having an enjoyable visit. Like all native animals they are protected in the park, and should be left unharmed. If they are found in areas heavily used by people, they should be reported to park rangers.
