Class B First-hand BFRO #27978

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

Summer 1973 approximately 11:00pm North Liberty, Johnson County, Iowa 4 witnesses

Account

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.
