SLIPPERY ROCK, Pa. (AP) — Authorities say a college student walking with friends at a state park in Lawrence County was injured when she fell about 80 feet from a cliff. The 21-year-old Pittsburgh woman was with four other people at McConnells Mill State Park in Slippery Rock when she fell Sunday afternoon from a cliff near Breakneck Bridge. The woman, who attends Slippery Rock University, had to be pulled up from the ledge in a rescue basket but was alert and conscious at the time. The woman suffered head and back injuries and was flown to a hospital. She’s expected to recover.
