YESTERDAY (09/01/2024): Hikers hear chatter and whoops of a large animal in Founders Grove, 33mi SE of Eureka

The witness and a companion were hiking the Founders Grove loop just after sunset when the woods went quiet and they heard chattering vocalizations. They felt immediate dread and judged whatever made the sounds to be huge. As they retreated toward their vehicle they heard movement in brush going deeper into the woods, and when the witness whooped back the chatter answered again. They hurried back to their car.

Mattole River Watershed (Lost Coast region) resident reporting loud knocks and vocalizations

The witness reports waiting alone at dusk at the gated entrance to a remote conservation area when they heard a very loud unfamiliar wail/scream-like call from a wooded slope a few hundred meters away. After additional calls and a pause, a second similarly loud and unfamiliar call answered from a different direction a few hundred meters away. The witness interpreted the exchange as communication between two large unknown animals and doubted a prank due to the remoteness and solitary 45-minute wait.

Campers Hear Unusual Evening Sounds

Two campers spent a rainy night at a campground after noticing a skunk-like odor on arrival. Through the night they heard ape-like hoots, single-note whistles, repeated wood-on-wood whacks from several directions, heavy two-legged footsteps, and nearby rockslides. They saw nothing in the dark and left the next morning, noting the steep bowl-shaped hillside could carry sounds from far uphill.

The witness said the sound was unlike an elk, human, or bear, and later heard a published Bigfoot scream recording that matched it.

The witness and a friend were walking their dog on a trail when the dog lunged up a steep embankment toward loud crunching and branch-breaking sounds from above.
