In 1948, scientists discovered a strange series of tracks embedded in rock along Spring Creek near Hallton. The rock was removed by paleontologists and taken to the Carnegie Museum of Natural History in Pittsburgh for study. Through the years it has been determined that the tracks had been made by a 7 foot-long relative of the modern scorpion 350 million years ago. A cast of the track resides at the Elk County Historical Society in Ridgway and the original is still displayed occasionally at the Carnegie Museum. The photo shows the scientists examining the tracks that were filled with plaster to make them more visible prior to their removal from the hill side.
