Bigfoot Sighting American Fork Canyon near Tibble Fork Reservoir

From Witness: I was up American Fork Canyon near Tibble Creek Reservoir. I thought I saw something a few minutes before when I was a little further away. It kinda scared me but I figured it was probably just a moose, elk, or maybe a bear. The area is pretty forested and I wasn't quite sure where the animal was. I only saw it for a second before it dissapeared behind some trees. I had to walk through some snow and trees to get to where I start the recording. I saw movement in the trees and that's when I move the camera to capture whatever it was. I was scared already but when it stepped into the clearing outside of the trees I was absolutely terrified. I only saw it for a second before I ran. The video captured more than I can remember. I only remember it being the most massive animal I have seen and I can't think about it without shaking. I don't want to say that it is for sure a bigfoot or sasquatch, but I don't know what else it could be. I spend a lot of time outdoors hiking etc, and I have never seen a bigfoot or even believed that they could be possible.
