Sound reports from resident in South Lake Tahoe

The witness reports hearing loud mournful screams and wails almost nightly for three months at a home south of South Lake Tahoe, often described as paired calls that converge then stop. Recordings were made mostly from a bedroom window between late evening and morning. The witness with a companion also backpacked, made all-night forest forays, and camped with bait to locate the source, finding tracks and bed-like structures with torn branches, while noting dogs refused some areas and little wildlife was seen.

"Unknown" Vocalization Sounds Heard and Broadcasted by a Group of Six Hikers, While Camping Overnight at Lake Shore Forest Service Campground

Six people camping at a forested lake campground heard a repeating whistle-whoop followed by an intense screech three times overnight, first from across a meadow, then from behind camp, then from very close to the tents. Each time they searched with flashlights and a spotlight but saw no eyes or movement apart from a small fox on the road. The next morning they found no tracks or other sign around the site and lake shore, and later doubted the fox could have made such intense sounds.

Screams heard in mountians near hwy 680

The witness and a visiting companion were awakened in the home in the middle of the night by a loud unnatural howling that seemed to pass the house and fade into the distance over about ten seconds. They stayed inside and assumed at the time it was dogs or coyotes. The witness later shared the account after reading similar descriptions while still doubting it was Bigfoot-related.

Truck driver has a short but memorable encounter

A semi-truck driver pulled over at a desert highway pullout at night and got out of the truck. He heard rocks falling, noticed a strong decaying odor that became gagging, and saw a large hairy biped cross the road in front of his headlights while making a loud grunt. Frightened, he got back in the truck and drove away.

Upright hair covered figure seen beside river

The witness parked by a river to fish for steelhead on a rainy winter afternoon and heard two loud whoop-like bellows. While wading downstream the witness saw two tall, hair-covered figures standing motionless across the river and noticed a cocoon-like bundle of grass on a root wad. After fishing back upstream the witness looked back to find the figures and object gone, and a return visit the next day was blocked by flooding.

Howl near Lytle Creek, California (1999)

The witness and his father were camping overnight in a canyon campsite. After dinner while sitting at the campfire they heard a distant loud howl from toward the canyon entrance that was answered by a whoop from behind camp. The two sounds continued in call-and-response for about 10-15 minutes and seemed to move closer and shift position, prompting them to load their guns. The sounds then stopped, and fresh snow overnight prevented any track search the next morning.

Shortly after graduation the witness and three friends camped overnight in a vacant house and were tormented by whistles and loud bangs on windows all night.

Fourteen inch by six inch tracks found

The witness was day-hiking alone in a remote wilderness area when they noticed a strong sickly-sweet, garlic-like odor they could not source. In the same area they heard a screeching vocalization they did not recognize as bear, mountain lion, or raptor. They also found large footprints near where they had eaten lunch, measuring about 14 by 6 inches, which they felt were not bear tracks but could not positively identify due to hard rocky ground.

Family has sightings and encounters in Santa Cruz mountains

In 2004 the witness was watching television in an outdoor covered porch at night and turned it off after hearing a noise. A very loud screaming roar was then heard close in front of the house, sounding three times while apparently moving along the driveway, with the last call ending in sounds like mimicked dog barks. The witness's parents also heard the sounds and nearby dogs reacted strongly.
