SLIPPERY ROCK TWP, Lawrence County — A Butler County man was rescued Sunday afternoon after breaking his leg in a hiking accident at McConnells Mill State Park, authorities said.

Joseph Valensky, 34, of Franklin Township was hiking with friends about 2 p.m. when he fell from rocks about 15 feet.

Park officials were notified shortly after the accident.

“He had a severe compound break of the left leg,” Jake Weiland, assistant manager at Moraine State Park, said of Valensky.

Members of the Allegheny Mountain Rescue Group and volunteer firefighters from Slippery Rock Township and Volant were called and rescued Valensky.

He was taken by ambulance to Allegheny General Hospital in Pittsburgh for treatment. His condition was not known this morning.

“Despite Sunday’s fall,” Weiland said, “it’s been an extremely safe season for us.”
