Timber Rattlesnake
(Crotalus horridus)

Description: Tan/brown with dark stripes across back. Orange/brown line down middle of back. Unmarked head. 23-25 keeled scales. Black tail.

Dimensions: 88.9-189.2cm. (95-74 1/2")

Warning! Rattlesnakes, Copperheads, and Cottonmouths belong to a group of snakes known as pit vipers. These dangerous snakes have a heat-sensitive sensory organ on each side of the head that enables them to locate warm-blooded prey and strike accurately, even in the dark. The curved, hollow fangs are normally folded back along the jaw. When a pit viper strikes, the fangs rapidly swing forward and fill with venom as the mouth opens. The venom is a complex mixture of proteins that acts primarily on a victim's blood tissue. If you hear a rattlesnake shaking its rattle, back away. The snake is issuing a warning, and if the warning is ignored it may bite. There are many factors (temperature being the most important) that determine how a snake will react when confronted by a human. Venomous snakes should always be observed from a safe distance. Pit vipers are never safe to handle. Even dead ones can retain some neurological reflexes, and "road kills" have been known to bite.

Breeding: Breeds in spring, after hibernation. Alternative years. 5-17 live young. 25-33cm (10-13") long born August- October. Females breed at 4/5 years.

Habitat: Wooded hillsides and rocky outcrops.

Range: Maine through Florida. Minnesota and Texas.

Discussion: Hibernates in winter, active April-October. Often hibernate with Copperheads and rat snakes. Wait for prey, coiled up. Rats, squirrels and mice form diet. Motionless if approached even by prey until it strikes. Longest living over 30 years.

Location: Garvin Heights wildwood bike trail 7-14-19 and Holzinger wildwood bike trail above woodland cemetery. (Winona County)

Both were stretch across bike trail. One onto of Garvin Heights extremely aggressive and did not rattle until right on top of it. I was there to cut up a fallen tree across trail. Snake was in the tree and mad as hell.  Snake above cemetery was stretched across a trail that is heavily used by riders and walkers. Myself and wife and son passed by the snake twice within minutes and did not see until second time. This snake was not aggressive and did not rattle. And yes it also had rattles but was about 3 feet long and small head appeared to be a younger snake. At this point I think someone should be advising the city to possibly post signs so people can be aware. A lot of the joggers and walkers wear headphones and will never hear a rattle until it’s too late.
