Seven Pillars of the Mississinewa: Scenic Hoosier Landform (GM-32)
"The Cliffs," or "Seven Pillars," about 3 miles southeast of Peru in Miami County along the Mississinewa River, is a little-known but scenic natural feature in northern Indiana. For many centuries, weathering along the well-developed jointing and thin bedding of the Liston Creek Limestone, and scouring action of the river waters have carved rounded buttresses and grotto-like alcoves in the north bluff of the river. The famous Frances Slocum Trail on the north side of the river passes along the tops of the "Pillars," but to get the greatest impact of its scenic beauty, you must observe this feature from the opposite side of the stream. The bluffs, or pillars, are about 25 to as much as 40 to 50 feet above low water.
