Arkansas Metal Detecting Laws — Research Overview

An orientation to metal detecting and treasure hunting rules in Arkansas, covering federal land, state land, private property, and who to verify with. This page is general research information, not legal advice. The state-level summaries below are our own category-level orientation and are not sourced to a Arkansas statute, code section, or agency ruling. Rules change and differ by unit — verify with Arkansas State Parks before detecting.

Public and federal land in Arkansas [UNSOURCED SUMMARY — confirm with the managing federal unit]: National forest detecting permitted with restrictions; ARPA fully applies. Federal land is also governed nationally by the Archaeological Resources Protection Act (ARPA) and the Antiquities Act, which prohibit disturbing archaeological resources over 100 years old without a permit.

State land in Arkansas [UNSOURCED SUMMARY — confirm with Arkansas State Parks]: Crater of Diamonds State Park uniquely allows surface diamond hunting (keep what you find).

Permits, permissions, and best practices in Arkansas [UNSOURCED SUMMARY]: Confirm WMA-specific rules with Arkansas Game & Fish before any organized search. Always carry written landowner consent for private ground and photograph the permission document.

Terrain and productive regions in Arkansas: Steep Ozark ridges, sandstone overhangs, and river bottoms with strong LiDAR returns for foundations and trails. Top areas to research include Ozark National Forest, Crater of Diamonds State Park, Ouachita Mountains.

Documented cases relevant to legal research in Arkansas: Jesse James Ozark caches; Confederate paymaster cache (Pea Ridge); Spanish silver caches along the Arkansas River — legal status of any recovered items depends on land ownership at the moment of discovery.

Federal rules that apply in Arkansas regardless of state law: ARPA (16 U.S.C. 470aa-470mm) protects archaeological resources 100 years or older on federal and Native American land; NAGPRA (25 U.S.C. ch. 32) governs Native American remains and cultural items; and the National Park Service prohibits metal detector use in park areas under 36 C.F.R. 2.1. Treasure trove and lost-property doctrine are set by state law and are not summarized here.
