You'll need to turn your audio up a bit to hear this. According to the person making the video, at the time this was made Sasquatch sightings were rampant on the Umatilla Indian Reservation. While the sounds caught on video could be some animal howling out... they are pretty weird sounding and hard to place exactly what animal could be making them. Regardless of what is making all the ruckus, it'd be pretty scary to hear it at night. It's a weird world sometimes.
