This trail descends to Jackson Falls, a beautifully sculptured cascade that seems ageless. But it isn't. For thousands of years before the falls existed, Jackson Branch flowed into this high valley, isolated from the Duck River below.
Then, in a classic case of "stream piracy," Duck River captured the Jackson Branch. The flooding river and other erosional agents wore away at the bluffs, cutting a new channel through faults in the rock. At the site of Jackson Falls, the diverted stream slipped down into Duck River valley, abandoning its former course.
