Identifying a Rattlesnake

As daily temperatures rise so does the likelihood of seeing snakes, including rattlesnakes, on trails. Snakes seek the warmth of rocks and pathways and are usually spotted after sunrise and up to late afternoon. In very hot weather, snakes will be most active in the evening and early morning hours when it's cooler, and will often seek shade from the hot sun.

A rattlesnake has a distinctive broad, v-shaped or triangular head and typically has a rattle at the end of its tail. The rattle sound is a warning by the snake which it uses to make its presence known. Rattlesnakes are venomous and a baby rattlesnake’s venom is just as powerful as that of an adult. These snakes play an important role in the environment by feeding on small rodents, rabbits, birds and any other wildlife that can be swallowed.

Stay Safe

Stay safe by staying on the trail and wearing sturdy boots and loose-fitting long pants. Remain aware of your surroundings and look ahead when possible to see that the trail is clear. If you’re walking with young children or dogs, keep them on the trail and away from tall grasses and brush near trails.

Snakes can be spotted on rocks, in the middle of the trail or off to the side of the trail. They won’t always warn with their rattlers. Do not pick up, disturb or corner a snake. Once you move away the snake will most often flee.

If Bitten. . .

If bitten, call 911 immediately. If you are on the trail, ask a companion or passerby to stay with you while someone else calls 911. Be as precise as possible about the trail you are on and the location.
