One of the most famous sections of the ET&WNC RR is the "High wall" During the winter of 1900 there was a massive flood that came through the gorge, wiping out several sections of railroad track. The Railroad needed to get trains running again, and QUICKLY. So they decided to build temporary wooden trestles, and fill them in with iron mine debris from Cranberry and then cap those off with stone/concrete walls. These original walls still remain supporting the tracks through the gorge this one in particular is the largest, and most dramatic.
