Tibbitts can be heard on the video asking the woman to give the elk some space, but the elk had already begun charging at her.
Tibbitts said the woman wasn't actually hit by the elk, but she tripped and fell when she tried to step back as the animal came toward her.
"She fell down before the elk came close enough to hitting her, and when that happened the elk backed away," he said.
The woman can be heard saying, "It's been a long time since I've been here. It won't happen again."
"I'm sure it won't," Tibbitts said.

So here is a little better video of what happened on my trip in Yellowstone park today. It is classic at the end she says "that won't happen again" and I replied I bet it won't.Posted by Jody Tibbitts on Sunday, May 29, 2016
