Campers get visited in the middle of the night and hear vocalizations.

The witness and a companion were camping in separate tents. Around 2:55 a.m. the witness was awakened by footsteps circling the tent and stopping behind his head, then realized the companion was still inside his own tent. When the witness moved to go outside, the unseen visitor crashed away through trees toward the river. Neither camper saw anything, and both reported feeling watched all night.

Campers hear loud scream at close range near Wapsipinicon River

The witness and a companion were camping overnight in a tent near a river when, about 15 minutes after turning in, they heard an extremely loud primal scream from very close range. The witness estimated the sound came from several feet off the ground and within a few dozen yards and remained in the tent out of fear. No visual contact or physical traces were reported.

Man recalls observing possible tracks and being screamed at on his paper route in Eldridge

As a paperboy delivering newspapers in Eldridge in early February 1981, the witness found very large human-like footprints in snow crossing the town from northeast to southwest, and found a second set retracing the route in reverse the next morning. Several days later, while delivering Sunday papers with his father driving, the witness tossed a paper against a door and immediately heard a loud scream from beside the house that he attributed to the same creature. The witness never saw the animal itself.

Possible approach to homes at night near the Des Moines River outside Saylorville

The witness was awakened at night by distressed dogs and heard a heavy, bipedal-sounding walker moving in dry reeds behind the house. Two large neighbor dogs repeatedly charged into the dark toward the sound and yelped as if struck, retreating to the porch light. The disturbance lasted about an hour and was also watched by family and neighbors. Days later the witness found reeds smashed flat along the fenceline and a large mashed area, but no identifiable footprints.

Possible tracks found in snow near Albia, Iowa

On a January 1976 afternoon the witness walked alone to a country club hill to sled. At the top he found bare footprints in snow with clear toe and heel outlines, sunk deep and spaced about three of his strides apart, running north to south into trees. He felt uneasy, sledded once, felt scared and as if watched while leaving, and headed home.

Memory of a possible encounter as young girls riding horses at night near the Coralville Reservoir

Four girls were riding horses on a moonlit night when their horses stopped and focused on a hilltop ahead. They heard a loud guttural growl mixed with vowel-like sounds and wood snapping, which frightened them. They galloped back to the farm where they were staying. The next morning they found a small wooden corral they had built on that hilltop broken apart.

Memory told of being chased off by frightening thumps and scream while hiking in Pikes Peak State Park

In September 1970 the witness and her husband were hiking a deserted trail in Pikes Peak State Park toward the Mississippi River overlook. From behind trees they heard extremely loud thumping sounds followed by an unfamiliar loud scream, without seeing the source. Frightened, they ran back to the ranger station to report what happened. Years later after watching television programs, the witness concluded the sounds were likely made by a bigfoot.

Two men remember hearing bone-chilling scream while parking at lookout point in Stone State Park

In summer 1970 the witness parked at a Stone State Park overlook at night with three companions. While he lay on a blanket with his date near bushes, a very loud scream erupted from very close by.

Scream
1 August 1959 Graf, Dubuque County, Iowa Class B #36817

Screams and stalking at a Girl Scout camp 13 miles west of Dubuque

In the summer of 1959 the witness was working as a counselor at a wooded Girl Scout camp. Over roughly two weeks, staff repeatedly heard footsteps moving through the tent area after dark, saw a dark figure near a hut, and found a director's tent ransacked, with deputies searching each day without finding anyone. On the final night the group heard extremely loud screams that moved from near a remote tent toward a pond and creek and found a large maple branch freshly broken off, leading the witness years later to wonder if the visitor had been a Bigfoot.
