Why am I Spooked?

I just found lost video footage of a trip I made to a place I nickname "Headless Raven". I was very spooked that day and could never figure out why. I was wearing shooter's earmuffs and apparently misinterpreted clacks or breaks I was hearing I guess. I didn't have any audio to review of that day until now. Quite a few clacks on this hike. It was early in my exploration of this place so I didn't know how active it was there yet!

Now I know why I was so uneasy!

Thanks for watching
