Status: metal detecting is subject to authorization requirements and potentially limited to specific lost-item recovery.
DCR bans metal detecting on its property by default, but park supervisors can give permission on a case-by-case basis for locating specific lost personal property - verbal OK on coastal/inland beaches, and verbal permission required in non-beach park/forest areas. Contact the individual park supervisor before detecting, and any historic item found (100+ years old) must be reported, not removed.

Check the specific property before detecting
A federal land overlay is a starting point, not permission. Check the managing office for the specific parcel, closures, detecting rules and restrictions on digging or removing objects. Never detect on archaeological sites or remove protected artifacts. ARPA protects archaeological resources over 100 years old on federal and Indian lands; other protections may apply to newer objects. National Park restrictions and state and local rules also apply. See our legal guidance.
Getting permission on private land
Use the county parcel office to identify the owner, ask before entering, and agree on where you may search and how finds will be handled. In the map, tap a location, check land information and save the spot. Use Asks to record permission requests and the letter tool to prepare an owner request. A saved spot or generated letter does not grant permission.
Using the map for research
- Open the state map and use Layers to show settlement records or beaches. Zoom in to explore individual markers.
- Compare historical maps with the current landscape. A GNIS historical designation does not establish that a location is abandoned or accessible.
- Check ownership and current rules before visiting. Named beaches are database records, not a verified list of public swimming or detecting areas.

No. Settlement and beach records are research leads, not public-access or detecting permission. Check the property manager, current restrictions and ownership before visiting. An empty federal-land result does not establish private ownership.
Massachusetts has 2,288 old and unincorporated settlement locations in federal records, including 51 marked historical in GNIS, plus 246 named public-record beaches. Old settlement sites, early schools and churches, old fairgrounds, and storm-scoured beaches are classic productive ground - with permission.
