Report 63077: Camper hears Ohio howls at 4-5am near Rimrock Lake.

Heard at least four howls in the morning between 4-5 am at silver beach camp grounds. The sounds were about a mile away but could here clearly in the morning. Thought was wild life or maybe a person. Then looked up a video on YouTube of people using a parabolic sound dish recording Sasquatch vocalizing sounds when I arrived back home. Was able to recognize the sounds from the video to what I had heard. It was a terrifying sound. The best way to describe it was a howl sound between a man and a ape. This is the link to the video of the sounds I heard:  Hopefully this video helps or explains my experience.
