Class B First-hand BFRO #48777

Campers hear possible night-time responses near Aeneas Valley Road

23 May 2015 night, about 9:45 to 10:00, dark Tonasket, Okanogan County, Washington 7 witnesses

Account

The witness was camping with a group on a friend's undeveloped property and spent two nights riding ATVs to a remote spot to try imitation yells and tree knocks for fun. The group reported hearing responding knocks, high-pitched vocalizations, loud grunt-like growls from in front and behind, and a very loud tree-breaking sound, all from about 75 to 300 yards away. Nothing was ever seen, and the group left the hillside quickly after the close growls, later listening from camp.
