All around you the views of nature give the full glory of what Mother Nature does with her gardens." - Richard Chamberlin

Remnants of huge bridge, national engineering landmark
The Kinzua Viaduct is a National Engineering Landmark and on the National Register of Historic Places. When this viaduct was built in 1881, it was the world's highest and longest railroad bridge at 301 feet tall and 2,053 feet long. An excursion train travels through the Allegheny National Forest and to the bridge. The scenery is awesome during fall foliage. In 2003, a tornado knocked down much of Kinzua Viaduct.
"I grew up in this area, and visited this bridge way before it was designated as a PA Park. My grandparents owned a farm down the road, and my brother and I used to ride our bikes down to the bridge and that was before any restoration was done and it was a little scary then to cross it. I remember the airplane crash that happened in the 1960s and they went across the bridge for the rescue and recovery of the victims. This park holds a very special place in my heart and as my children were growing up, we made sure they too had their memories of this bridge and who would dare to cross it.
"My heart was broken when the tornado hit and took a large part of the bridge down, it was a silent moment for me to see it, and the surrounding area devastated by the destructive nature of the tornado. I'll still visit this park, whenever we're in the area, because it's part of me, it brings back old memories and I'll watch the regrowth of the beauty surrounding this bridge." - Linda L. Exley

Accustomed to the high-tech world, many are intrigued to learn how we harnass the power of Slippery Rock Creek to grind corn meal when we demonstrate the stone grinder. As a volunteer, I enjoy leading tours of this historic mill as well as assisting local and even international visitors to enjoy our beautiful 400 ft. gorge, a sight worth the trip alone." - Polly Shaw
