Just found this on Sunday, though I suspected something was there based on Google Earth images. Based on the impressive pedestrian bridge (now closed) that spans the gorge, this place was no secret 20 years ago and it isn't today. I arrived Sunday to find a parking area and a trail system had been put in after the Google Earth image was taken.
At close 1/2 mile, it's likely the longest gorge left in the area (the longest was destroyed by a quarry) and features some cascades and a pair of waterfalls. It's possibly the deepest gorge also, rivaling Hayden Gorge further south. I'll have to trig it out some time, I'm estimating as deep as 70ft.
Getting to the gorge floor wasn't safe, I'll have a rope next time. The trails make the rim very accessible, just find Shawan Falls Dr. in Dublin ohio and you'll find the parking area, the trails, and the falls.
Some pics:
Upper falls:
Lower falls, a bit dry:
Concrete T-beam bridge. Fenced on both ends, but you can still get out on it. I have some guesses why it's closed, but only guesses.
Looking down from the bridge at the lower falls:
Long way up:
Highly recomended stop since it's right int he area. It essentially forms an effective zombie barrier for the northwest of old Dublin proper. Easy to find, tough to explore.
Also, a teaser from another site in the area:

I was alone, so that's as far in as I went. There are 3 such cave in the area, I'm fixin to probe them.
