Class B First-hand BFRO #18584

Possible vocalization heard near Pyramid State Park

Fall 1975 about 10pm Pinckneyville, Perry County, Illinois 1 witness

Account

The witness was outside at a relative's rural farm at night when a loud, hair-raising vocalization was heard from across a lake. The witness ran to a shed where two relatives were working but had not heard the sound. Horses nearby became agitated and later avoided the area where the sound originated until daylight.
