Hikers hear "weird vocal exchange" from unknowns near Lake Ann

9 September 2014 around 6:00 pm Winthrop, Chelan County, Washington 4 witnesses

Account

The witness and a companion were hiking toward Lake Ann in the evening when they heard a prolonged exchange of high-pitched, varied and eerie calls between two distant, inaccessible points across the valley. The exchange lasted several minutes. Shortly afterward they met two other hikers who had also heard the sounds and found them strange.
