I had not been back from the wilderness for even an hour this morning when the radio started to crackle. Soon I heard an ambulance racing up into the park, lights and sirens ablaze. A tour bus full of French visitors had stopped at Balanced Rock, one of our least dangerous and most innocuous locations. One unfortunate 63-year-old had stepped off the sidewalk by about fifteen feet to click a photo, and was bitten in the ankle by a rattlesnake. He was already having difficulty talking and had a pulse of 150. The local hospital couldn’t help him much, as antivenin is available only if one knows exactly which species inflicted the bite*, so he was helicoptered to Grand Junction, Colorado. I expect he’ll be in the hospital for a week or ten days and then have a long, slow convalescence. Kind of ruins his American vacation.
Was it one of our shy Midget Faded Rattlesnakes? They are nocturnal, except that sometimes the males are out scouting for new territory this time of year and perhaps one was just there to get stepped on. Or, perhaps it was an atypical species of rattler (not our small shy one) that was just passing through. It makes treating the victim difficult.
You don’t want to mess with our Midget Faded. Shy, yes; benign, no. Their neurotoxin is one of the most potent of rattlesnake venoms. The typical effect of a bite from a Crotalus species is similar to most viper bites with massive edema (swelling) and tissue destruction. I hope the man from France recovers fully and quickly.
This is only the second known venomous snakebite in our national park, but the maps around here are filled with place names like “Rattlesnake Canyon.” I guess if you come to Utah, you’re taking a risk…
