Possible vocalizations on Little Si Trail outside North Bend

Two people hiking in the morning heard a repeated loud alarm-like holler ending each time in a strange ape- and human-like vocalization. The witness imitated the sound a few times, and both listeners concluded it could not be human or a wolf/coyote due to lung capacity and lip-like articulation. Believing the source sounded closer and could be a large unknown animal, they ran back to the car without seeing anyone else on the trail.

An investigator later visited the area and reported a possible large footprint on the hillside.

Hiker Hears Loud Vocalizations and Thumps

The witness sat near a swamp waiting for frogs to resume and heard rapid deep thumping from a hillside across the swamp, followed by a second similar series some distance away on the same hill. Shortly after, a short constant hollow call came from each thumping area in turn. The witness stated the sounds were not woodpeckers and asked whether such thumping indicates proximity.

Family hears a howl while camping in the front yard

The witness reports camping with family in the front yard late at night when they heard prolonged loud moaning from up the hill. The unfamiliar sound was frightening and the group eventually went indoors to sleep. Years later the witness felt the sound matched a Bigfoot vocalization heard on television.

Late night encounter by young campers in Maple Valley Wa

A youth camping group spent the night in a clearing near dense blackberry brush. Late at night the reporter and companions heard movement approaching through the brush, then retreated to sleeping bags.

At dawn no footprints were found on dry ground.

Loud vocalizations heard near Stevens Pass

The witness was walking alone on a spring morning near Scenic, Washington when an extremely loud sound was heard three times from about half a block away near old railroad bunkhouses. The sound was described as starting like a roar and rising to a shrill pitch, repeated with short pauses. The witness did not see the source and could not identify it as any known local animal.
