Make lots of noise. Talk to your companions, sing to yourself, wear bells, or whistle. Noises will alert snakes to your presence and encourage them to move on rather than risk a meeting neither you nor the snake wants.
Listen to the noises around you. You can often hear the movement when snakes slide through dead grass or dried leaves.
Carry a long walking stick with you and use it to comb through tall grass, dead leaves and huckleberry bushes. If you do inadvertently disturb a snake, it is much better to have a few feet of walking stick between you and the offended reptile.
Never put your hands and feet anywhere you cannot see. Step onto obstacles such as fallen logs or large rocks rather than over them, putting your foot down only after checking the far side of the object for snakes.
Give any snakes you do encounter a wide berth. Do not attempt to catch or move them. If one is coiled in the huckleberry bush you were heading for, choose a different bush rather than disturb the snake. If you do startle a snake, hold perfectly still until it moves on, or slowly back away. Avoid dead snakes as well as live ones – recently deceased snakes often experience muscle spasms and may still be able to bite.
