Hanging Rock and Wabash Reef National Natural Landmark
Hanging Rock and Wabash Reef National Natural Landmark, Natural landmark in Wabash County, United States
The limestone structure rises 75 feet above the Wabash River, featuring a natural exposure of fossilized coral reef from the Silurian Period.
The 4-acre site received its National Natural Landmark designation in 1986, preserving a geological formation that dates back 420 million years.
Indigenous Miami people and European settlers utilized this prominent geological feature as a navigational reference point and observation location.
Visitors can access the 0.2-mile trail around the 200-foot-wide base of Hanging Rock from sunrise to sunset through Acres Land Trust management.
The river's erosion created an overhanging formation at the top of the rock, positioned 65 feet above the Wabash Valley floor.
