Fortunately, as Tibbitts write on Facebook, the elk didn't actually launch the impolite selfie-snapper - she tripped and fell on her own. But things could have gone much worse.
According to National Parks Service spokesman Jeffrey Olson, there's a growing problem of people putting themselves at risk of being injured by an animal just to snap a photo.
"If you're going to do a selfie, you have to use the widest lens you can," he told ABC News. "There is just kind of an ignorant danger, and then there is a whole other level of the really self-obsessed selfie shooters - and what they do is try to close the distance between them and the animal."
In other words, keep your selfies to yourself.
