Metal Detecting Laws in Indiana
Indiana State Parks emphasizes preservation of natural and cultural resources, and official property materials such as Brown County State Park expressly prohibit metal detectors. Fish and wildlife properties such as Willow Slough also list metal detecting as prohibited. Do not use a detector on DNR property unless the property gives explicit written authorization.

Local complication
Indiana Dunes State Park is separate from Indiana Dunes National Park, but neither name creates detector permission. The national park follows NPS prohibitions; the state park protects dunes and cultural resources under Indiana rules.
Private property
Obtain written owner permission covering the exact boundary, tools, restoration and division of valuable finds. The owner cannot waive laws protecting burials, human remains, archaeological resources, utilities or environmental features.
Federal and tribal land
National parks, forests, refuges, Corps projects, BLM parcels, military installations and tribal lands use separate authorities. Identify the parcel before interpreting a state rule.
Do not confuse access with detecting permission
| Location | Required check | Common mistake |
|---|---|---|
| Indiana state park or managed site | Read the current rule and obtain any site permit or manager approval. | Assuming an entrance pass authorizes detecting and digging. |
| Beach or reservoir | Confirm the sand zone, season, hours, water boundary and recovery tools. | Extending a narrow beach exception into dunes, uplands or adjacent federal land. |
| Wildlife or conservation land | Use that division’s rules rather than the state-park rule. | Assuming all state-owned land follows one policy. |
| Federal land | Identify NPS, USFS, BLM, refuge or Corps jurisdiction and local orders. | Treating public access as permission to remove objects. |
| Private land | Get written owner consent and a finds agreement. | Ignoring protected burials, archaeology or utility hazards. |
Four checks before you unpack the detector
1. Confirm the parcel
Save the agency map or parcel record. Shorelines and reservoirs often contain several managers within walking distance.
2. Separate four permissions
Ask separately about possessing the detector, operating it, excavating or scooping, and keeping the object.
3. Record the conditions
Keep the permit, email or name of the official, together with dates, hours, boundary, depth and tool restrictions.
4. Stop at protected context
Do not disturb burials, artifact clusters, foundations, battlefields, shipwreck material, ordnance or culturally sensitive features.

Leave the site better than you found it
Where detecting is authorized, use only the approved recovery tool and the smallest practical opening. Replace plugs, remove sharp trash, stay out of planted and restored areas, and do not interfere with visitors or facility operations. A signal is not proof that an object may be kept.
If the target may be human remains, ordnance, a burial object, an archaeological deposit or a component of a historic structure, stop. Do not clean or reposition it. Back away, record the location safely and notify the manager or law enforcement as appropriate.
