During the summer, numerous snakes may be seen crossing or warming themselves on the road.  Rattlesnakes, in particular, descend from their hibernation sites in the rocky slopes of the Ruby Mountains and the Maverick range to forage at lower elevations (including the refuge and surrounding valley).  After feeding, shedding, and perhaps mating during the course of the summer, the rattlesnakes will return to their hibernation sites in the fall.  Drive slowly on Ruby Valley Road to avoid hitting them.

Many people fear rattlesnakes, but they are not naturally aggressive.  Their rattle is, in fact, an acoustic warning device that allows them to say "Here I am.  Don't step on me."  Biting is a last resort, as rattlesnakes typically strike when retreat is not an option.  An injured or frightened rattlesnake will bite to defend itself.  The most common rattlesnake bites are on the hands and forearms, especially of teenage boys and men in their early twenties that just can't leave them alone!  Additionally, care should be taken when walking in brush not to step on one and dogs should be kept on a leash and under control in rattlesnake territory. Still, it is important to note that more people are killed in the Unites States each year by livestock and domestic dogs, even lightning strikes, than by rattlesnakes.

*Handling rattlesnakes requires knowledge and use of safety precautions as well as some specialized tools.  Even then sometimes the most experienced of herpetologists can occasionally be bitten.  Collecting of snakes for study also requires a permit from the state.  On the refuge, all reptiles and amphibians are protected.*
