Photos from Fall Creek Gorge near Attica, Indiana.
This is a small Nature Conservation area (the parking lot only provides parking for 6-8 cars) in located along Fall Creek which passes through sandstone cliffs.
The action of the water along the narrow bed has cut deeply into the cliffs and has created numerous small basins called the Potholes. These potholes range from about a 1 foot wide to as much as 6 feet wide and have depths of 4 - 5 feet.
At the end of the pothole section the river bed levels out where you can walk upstream to a small waterfall.
