Explore the world's largest exposed Devonian fossil beds, 390 million years in the making. The Falls of the Ohio National Wildlife Conservation Area, located in Clarksville, Indiana, on the banks of the Ohio River, offers a truly unparalleled journey through geological time and natural beauty. This 1,404-acre bi-state area preserves a prehistoric coral reef and significant natural habitats, offering stunning panoramic river views and a rich tapestry of both ancient and human history.
At the heart of the experience is the state-of-the-art Interpretive Center, which brings the story of the Falls to life through 3,000 square feet of interactive and immersive exhibits. Visitors can delve into the "Ancient Sea," discovering the diverse creatures like horn corals and crinoids that once thrived here, or explore "A Changing Land" to understand glacial impacts and early human history. The center also features a "Wildlife Observation Room" where various bird species, including the iconic Great Blue Heron, can be seen year-round. Outside, wander the Woodland Loop Trail, offering glimpses of native plants and potential sightings of diverse birdlife, from wading birds to majestic bald eagles and peregrine falcons.
A visit to the Falls of the Ohio is an unforgettable blend of education, outdoor exploration, and historical reflection. Whether you're marveling at the ancient fossil beds, observing diverse wildlife in their natural habitat, or tracing the footsteps of pioneers like George Rogers Clark and Lewis and Clark, the area provides a unique connection to millions of years of Earth's history and the vibrant ecosystems of today. Don't forget to bring the Snappit nature identification app along to scan local species.

Check River Levels
Before visiting, especially if you plan to explore the fossil beds, check the current Ohio River levels. Low water is crucial for optimal fossil viewing.
Wear Appropriate Footwear
The fossil beds can be uneven, muddy, and slippery, so sturdy, waterproof shoes with good grip are highly recommended.
Bring a Spray Bottle
If the fossil beds are dry, misting the rocks with water from a spray bottle can make the intricate fossil details stand out more clearly for viewing and photography.
Visit the Interpretive Center First
Start your visit at the Interpretive Center to gain context about the geological and historical significance of the area, which will enhance your outdoor exploration.
Stay on Designated Paths & Observe Rules: While exploring the fossil beds, remember not to remove any fossils from the site (unless from designated collection piles). Keep pets on a leash.
