Across from Louisville, the Falls of the Ohio reveals an ancient sea floor

A short regional trip can lead to a much longer view of time. Across the river from Louisville in Clarksville, Indiana, Falls of the Ohio State Park preserves Devonian fossil beds about 390 million years old, remnants of an ancient environment very different from the Ohio River landscape above them today.

The park encourages visitors to observe and learn, but fossil collecting is prohibited on the beds and riverbank. Only designated collecting piles of quarry material near the interpretive center allow removal under the park's guidance. A loose-looking piece on the fossil beds is not an invitation to take it home.

Indiana DNR says August–October often provides the best exposure as river levels tend to be lower, but actual conditions determine what can be reached on a given day. Check current notices and speak with staff before heading onto the beds. Treat an archival low-water photograph as a historical view, not today's access report.

The park is at 201 West Riverside Drive. Current interpretive-center admission is $9 for ages twelve and older, $7 for ages five–eleven and free for younger children, with $2 parking. Its indoor exhibits offer another way to explore when conditions limit outdoor access. Bring a question about a visible shape or fossil pattern and leave the original in place for the next visitor.
