North Dakota Metal Detecting Laws — Research Overview

An orientation to metal detecting and treasure hunting rules in North Dakota, 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 North Dakota statute, code section, or agency ruling. Rules change and differ by unit — verify with North Dakota Parks and Recreation Department before detecting.

Public and federal land in North Dakota [UNSOURCED SUMMARY — confirm with the managing federal unit]: BLM and grasslands permit detecting outside protected sites.
