Vocalizations heard by expeditioners on Olympic Peninsula

October 2004 night, completely dark [Between Aberdeen And Forks], Jefferson County, Washington 4 witnesses

Account

On the first night of an October 2004 expedition, four participants walked a stretch of mountain road making wood knocks. They heard deep grunting sounds from the woods, then later heard two loud scream-like vocalizations from different sides of the road, one a few hundred yards away and one within about 50 yards. They stated the screams started as a low moan and rose to a high-pitched screech and were unlike any known local animal sounds.
