Motorist observes a dark shaggy figure running on the road in daylight near Ogden

The witness was driving west on a paved rural road after collecting a child from camp when a dark upright figure was spotted walking on the gravel shoulder well ahead. As the vehicle closed the distance, the figure looked toward the vehicle, ran along the shoulder, cut across into the opposite lane while moving uphill, then turned off onto a tractor access and vanished into a cornfield and woods about 100 yards away. The witness's son in the vehicle also saw the figure, while the daughter did not, and the witness described it as dark and shaggy with a fast, unusual motion that left doubt about whether it was human.

After a smaller, more distant figure gave piercing screams and a closer figure answered with a guttural grunt, the figures started moving toward each other and the witnesses left for their truck.

Hunter experiences eerie silence, foul odor and possible wood knocking in the Cardinal Marsh Wildlife Management Area

Roughly an hour later he heard paired thudding sounds like logs or a log hitting a tree, which repeated again after about another hour from the same location. The woods around his stand were unusually quiet, while his companion farther upstream reported normal wildlife activity.

Hunter encounters freakishly large tracks in a field south of Cresco

The witness was hunting on public land in northeast Iowa just before dark when they found large single-file tracks in snow crossing an alfalfa field.

The tracks were estimated to be a few days old and were heading east.
