An old #railroad #bridge along the #WestPennTrail. This bridge was originally much higher. When they built a nearby dam, this valley was flooded. These days you have to check the water level before you go out, because it sometimes gets submerged.
The main trail network was well-maintained gravel, but there were dozens of dirt paths cutting through the thick woods. I saw a lot of what looked like art installations in the woods too -- I'll have to go back.
