Crossing ravines is a normal part of marking timber in the Driftless region, and sometimes the ravines are beautiful. This one was especially fun to see. Water cascades over the bedrock in several small falls. The drop of this falls is about eight feet, and there is a deeper pool worn into the rock. I think bits of rock eroded it away over the years. One thing that you can’t see clearly from the photo is that the rock around the small pool of water is undercut so the pool gets bigger in diameter below the rock surface.
