Rock River Falls, photo by gkretovic.

Regular readers of Michigan in Pictures know that  Go Waterfalling is the source for Michigan waterfall information. Their Rock River Falls entry says:

This wild waterfall is hidden in the Rock River Wilderness Area north of Chatham. Reaching it will require you to drive down some old logging roads and hike a mile or two along some ill defined trails, but if you are looking for a good waterfall adventure it is worth it.

Rock River Falls is in the Rock River Wilderness Area in the Hiawatha National Forest, which is just north of Chatham. This area is not well marked, but finding the falls is not too hard.

There’s detailed directions at the link above there and Greg also has this photo on his map. See it bigger along with a few other views in his slideshow
