Hikers are startled by unusual sounds in Staunton State Park

The witness and a companion were resting quietly on a rocky outcropping during a daytime hike when they heard a low growl-like exhalation immediately followed by a higher-pitched whoop from the forest below. The sounds were attributed to a single unseen animal about 30-40 yards away that seemed startled by a passing mountain biker. They searched the area a few minutes later but found nothing and heard nothing further.

Woman describes vivid early morning sighting just below Independence Pass
