Metal Detecting in Indiana

1. The rule, in full

Indiana – 312 IAC 8-2-10

Read from the Indiana Administrative Code, 2026 Edition, at iar.iga.in.gov, article 312 IAC 8 ("Public Use of Natural and Recreational Areas") in full. Checked 3 Oct 2026.

Rewritten 3 Oct 2026. The previous version of this entry quoted a reconstruction of the rule rather than its text – the lead-in and subdivision (7) folded into one reordered sentence – and omitted subdivision (10), which is the part a reader acts on. Recorded in SOURCING-AUDIT.md.

Operative text, 312 IAC 8-2-10, "Preservation of habitat and natural and cultural resources":

"Sec. 10. Except as authorized by a license, a person must not do any of the following within a DNR property:
(5) Damage, interfere with, or remove: (A) a work of art; (B) an artifact; (C) a rock or mineral; (D) a shipwreck; (E) an archeological site; (F) a historic site; (G) a building; or (H) a sign.
(7) Use a metal detector, except on a sand, swimming beach as approved by an authorized representative.
(10) Dig or excavate any material from the ground." Authority: IC 14-10-2-4; IC 14-11-2-1.

Subdivisions (7) and (10) have to be read together, and that changes the answer. Detecting is permitted on a sand swimming beach that an authorized representative has approved. Digging is not – anywhere within a DNR property, with no beach exception attached to (10). Subdivision (5) separately bars removing an artifact, a rock or a mineral.

So Indiana permits the sweep and bars the recovery, unless a license authorises it. A page that carried only (7) would tell a reader they may detect on the beach and leave them to discover the rest with a trowel in their hand.

Scope: all DNR property, which is why Indiana needs only one instrument. "DNR property" is defined at 312 IAC 8-1.5-6, and the article's own subdivision (4) enumerates the kinds: "(A) A state park. (B) A reservoir property. (C) A fish and wildlife area. (D) A state forest." That is internal evidence the article reaches all four, rather than an inference from the agency's name.

Determination: all Indiana DNR property – state parks, reservoir properties, fish and wildlife areas and state forests alike. Does NOT reach municipal parks. The forestry and wildlife sweep of 3 Oct 2026 found no separate instrument for any other class of Indiana state land, and none is needed: 312 IAC 8 reaches them all through one definition.

Statewide: IC 14-21-1, read from the Indiana Code

Read from the Indiana Code itself – IC 14-21-1-2, IC 14-21-1-26 and IC 14-21-1-29 copied from iga.in.gov by Jason Smith on 13 October 2026, each archived with its sha256. iga.in.gov serves the Code client-side and returned no section text to any automated route, so these sections were taken by hand. Nothing in this section now rests on a secondary compilation.

What counts, IC 14-21-1-2, "Artifact" defined:

Sec. 2. As used in this chapter, "artifact" means: (1) a feature that is: (A) nonportable evidence of past human behavior or activity; (B) found on or in the ground, including structural remains; and (C) formed before December 31, 1870; or (2) an object made, modified, or used before December 31, 1870.

So the test is a date, not an age. An object made, modified or used before 31 December 1870 is an artifact however old it happens to be, and nothing younger qualifies however historic it looks. IC 14-8-2-16 carries the same definition across the rest of title 14.

Digging in order to find artifacts, IC 14-21-1-26:

"Sec. 26. (a) A person who disturbs the ground for the purpose of discovering, uncovering, or moving artifacts, burial objects, or human remains must do so in accordance with a plan approved by the department under section 25 of this chapter or under IC 14-3-3.4-14 (before its repeal)."

"(b) A person who recklessly, knowingly, or intentionally violates this section commits the following: (1) A Class A misdemeanor, if the violation does not involve disturbing human remains. (2) A Level 6 felony, if the violation involves disturbing human remains."

Note what section 26 does not say. It carries no land qualifier – no distinction between state and private ground on its face – and it does not define "disturbs the ground". Whether a particular method of searching amounts to disturbing the ground is not something the section answers.

Finding something while digging for another reason, IC 14-21-1-29:

"Sec. 29. (a) A person who discovers, uncovers, or moves an artifact or burial object while disturbing the ground for a purpose other than the discovery, uncovering, or moving of artifacts or burial objects shall do the following: (1) Immediately cease disturbing the ground and the area within one hundred (100) feet of the artifact or burial object. (2) Notify the department within two (2) business days after the time of the disturbance."

"(c) A person who violates subsection (a) commits a Class A infraction."

Sections 26 and 29 divide by purpose, and that is the whole architecture. Section 26 governs ground disturbed in order to find artifacts and requires an approved plan in advance. Section 29 governs an artifact that turns up while the ground is being disturbed for a purpose other than finding artifacts, and imposes a duty afterwards: stop within a hundred feet, notify within two business days. The hundred feet and the two business days belong to the second case only.

Subsection 29(b) then lets the department authorise the work to continue, with or without conditions, or require an approved plan – and that plan power lapses: "this subdivision does not apply after ten (10) business days from the date that the department receives notice."

Determination: an artifact is anything formed, made, modified or used before 31 December 1870. Disturbing ground in order to find one requires a plan approved by the department under section 25, on pain of a Class A misdemeanour, or a Level 6 felony where human remains are disturbed. Finding one while digging for something else carries the stop-and-notify duty in section 29 and a Class A infraction for failing it. Section 26 states no land limit.

2. Cities in Indiana that publish a rule

6 cities in Indiana publish a rule we can quote, out of 84 checked.

Of the 84 checked, 45 had pages on the city’s own site that we found and read. For the other 39 we could not locate a municipal source, so nothing is claimed about them either way.

3. County rules

County rules exist in Indiana, and they govern county land only. 3 county rules surfaced while checking cities in this state. Each was read and then set aside, because a county park rule does not answer whether a city park allows detecting, and it is not the state rule either. They are listed because their existence is the useful fact: if you are in a county park, a separate rule probably applies to you.

0 of these 3 name their county in the text that was read; the rest name only “county park” or “county parks”, so the source is given instead of a county name. A county is never inferred from a web address.

4. Cities checked - no published rule

76 cities in Indiana were checked and have no published rule on this page. Of those, 73 returned no rule, and 3 did return something that has not been published – mostly rules that turned out to govern county land, which are in the county section above. A city here is not a city where detecting is allowed. It is a city whose own published material did not answer the question.

All 76 were checked on 13 September 2026, in one sweep, so that date applies to every row.

6. Land this page does not cover

This page answers for Indiana state land, and for city and county land where the state rule reaches it. Several other kinds of ground are not covered here, and naming them is more honest than letting a reader assume the page is complete.

Tribal land. This directory does not cover it, and will not.

There are 574 federally recognised tribal nations. Each is a sovereign jurisdiction with its own law, its own permitting, its own enforcement and its own cultural-resource provisions, and none of them is answered by a state's code or by any federal rule quoted on these pages. A one-line instruction to "get tribal permission" would be worse than this paragraph, because it implies one process and one authority where there are 574. If you are on or near tribal land, the governing law is that nation's, and the place to ask is that nation's own offices. Nothing on this page applies there.

BLM land is covered, partly, in its own place. The Bureau of Land Management holds about 245 million acres and the federal rule names metal detectors and permits them, which is the opposite of the national park rule. See BLM land: the detector is named, and permitted. That page covers the base regulation; it does not yet cover the supplementary rules individual BLM State Directors issue for particular field offices.

Named and not examined. These are recorded so their absence is visible rather than silent. No claim is made about any of them:

• Military withdrawn land, including ranges and training areas.
• Bureau of Reclamation land, which surrounds a great many reservoirs.
• Water district and irrigation district land.
• Wilderness, Wilderness Study Areas and National Conservation Areas, which carry designations of their own. And one general point about signs. The commonest piece of reasoning in this subject is "there was no sign, so it was allowed." Arizona's State Land Department answers it in writing, in condition 2 of its own Recreational Permit terms:

"You will comply with all laws, rules, regulations and ordinances. Posting is not required for these provisions to be enforceable."

That is Arizona's sentence about Arizona's provisions and this directory does not present it as the law of any other state. But the proposition it states is the one to carry: nothing read for this project makes a published rule's enforceability depend on a sign at the boundary. Where posting does matter, a specific provision says so, and that provision is quoted on the page where it occurs.
