Fall colors reflect in Mill Creek, Cataract Falls State Recreation Area, Indiana, USA.
Fall colors reflect in Mill Creek, upstream of Lower Falls in Cataract Falls State Recreation Area, an hour southwest of Indianapolis, near Cloverdale, Indiana, USA. Autumn foliage colors were brilliant but water volume was low for this photo in mid October 2015. The park's limestone outcroppings formed millions of years ago when the region was covered by a large shallow ocean.
