## Direct answer

A tightly defined Indiana collecting opportunity: rocks may be removed only from the designated quarry-material piles behind the interpretive center.

## Location and material

- State: Indiana
- Area: Falls of the Ohio State Park, Clarksville
- Category: Fossil collecting
- Collection status: Collecting allowed
- Expected material: Devonian coral fragments, Brachiopods, Common quarry-supplied fossils

## Authorization

Indiana DNR states that the collecting piles are the only place at Falls of the Ohio where rocks may be removed. The natural fossil beds and riverbank are strictly no-collection.

## Access

Check current park hours, parking, interpretive-center admission, river level, and whether the collecting piles are available.

## Tools, limits, and season

- Tools: Use gentle hand searching in the supplied piles unless staff post a different method. Do not hammer, pry, or remove material from the natural fossil beds.
- Limits: Only material from the designated piles may leave. Fossils embedded in the exposed riverbed must remain exactly where found.
- Season and current status: The park is year-round, while fossil-bed visibility depends on river level; pile availability and programs can change.

## Conditions

- Collect only from the marked piles.
- Remove nothing from the riverbank or fossil beds.
- Follow staff direction and posted limits.
- Keep children away from traffic and the river edge.

## Geology

The famous exposed beds preserve a Devonian tropical marine ecosystem about 390 million years old.

Quarry-supplied pile material lets visitors practice recognizing corals and other invertebrates without damaging the protected bedrock record.

## Field plan

1. Open the current official source and check alerts before leaving home.
2. Confirm the property boundary, parking location, and activity rules on arrival.
3. Begin with observation or surface searching and make the smallest possible disturbance.
4. Photograph context before handling any material that the current rules allow you to keep.
5. Pack out every item you brought and leave protected or uncertain material in place.

## Safety

- The Ohio River can rise quickly and cover the fossil beds.
- Wet limestone is slippery and summer rock can become hot.
- Remain out of closed river areas.
