I took some this this past weekend to visit a friend out in Iowa and during the time we took a little like over at the Whitewater Canyon overlook. The hike itself wasn't that interesting, mostly flat, cut down prairie leading towards the main attraction, the overlook.
The overlook itself was very pretty. We tried to hike down some to see if we could hit the little stream at the bottom, but the 3 different path that we attempted were all at various stages of blocked. So instead this is the best that we saw of it.
