Colorado metal detecting rule layers
Quick answer: a rule applies because of jurisdiction and managing authority, not simply because a place is publicly accessible. This page contains only rule layers actually inherited by current Colorado records.
How to read these rules: detector use, digging, target recovery, artifact protection, permits and designated zones can be controlled by different provisions. A restrictive recovery rule is not automatically rewritten as a detector-possession ban, and an access permit is not automatically treated as recovery authorization.
Colorado metal detecting law questions
Is metal detecting legal on all public land in Colorado?
No. Public access does not create metal-detecting or target-recovery permission. The controlling rule depends on the land manager, property purpose, detector-use rule, digging/recovery restrictions, protected-resource law and any permit or designated-zone requirement.
Does a recreation, hunting or access permit authorize metal detecting?
Not unless the controlling rule expressly says it does. Access credentials and detector/recovery authorization are treated as separate legal questions in this database.
Can a map pin prove where metal detecting is permitted?
No. A map pin is only a public visitor/access reference point. It is never treated as a property boundary, detecting zone, archaeological location or legal permission boundary.
How many controlling rule layers are listed for Colorado?
13 current rule layers are represented on this page. Each rule entry identifies its managing authority, status, official source, verification grade and verification date.
Boulder, Colorado
Boulder OSMP states a permit is required to collect cultural, historical, plant, animal or mineral specimens or related materials; collection permits are typically issued for research purposes only and collection without a permit is prohibited.
Important exceptions: Ordinary trail/open-space access does not authorize detector recovery or collection. Approved research/collection permit terms control.

Colorado Parks and Wildlife park regulations protect park property and resources from unauthorized damage/removal. Ordinary park entry, camping, hunting, fishing, boating, gold panning or other recreation does not establish permission to excavate or recover detector targets. Current P-1 park-specific rules must also be checked for the exact property and posted zone.
Important exceptions: Arkansas Headwaters Recreation Area expressly allows recreational gold mining except where posted prohibited; that mineral-recreation exception is not a blanket authorization to recover historic or archaeological objects. Pikes Peak Recreation Area was newly established in 2026 and is governed by current P-1/posted conditions.

CPW states that access to Lone Mesa is presently restricted to hunting, volunteer and educational programs and that Lone Mesa is not open to other visitors at this time. Metal detecting is therefore not a general recreational access pathway.
Important exceptions: Qualified hunting access does not create detector, digging or recovery permission. Follow the purpose and terms of the specific authorized access.

Colorado
CPW states that each State Wildlife Area has different allowed activities and most recreation is wildlife-related. A required SWA pass or hunting/fishing license establishes entry eligibility, not metal-detecting, excavation or object-recovery permission.
Important exceptions: Check the current SWA finder, property restrictions, seasonal closures, ownership, posted rules and the intended activity before detector use or recovery.

Colorado Natural Areas guidance tells visitors to stay on designated trails, leave rocks, artifacts and plants where they are, and follow landowner rules. Designation does not itself create public detector or collection rights.
Important exceptions: Many natural areas are not generally open to the public; exact ownership and access terms control. No artifact/mineral collection permission is inferred.

BLM guidance permits metal detectors as hand-prospecting tools on suitable public lands when use causes no more than minor surface disturbance, but developed recreation sites, active mining claims, special designations and protected cultural/historic resources can restrict or prohibit use and recovery.
Important exceptions: Historic and archaeological resources are protected; do not collect cultural objects merely because a detector is otherwise lawful. Confirm current land status, mining claims, special-designation rules, closures and local restrictions.

An NPS national-trail identity does not make the entire Colorado corridor NPS-administered. Apply the NPS detector prohibition on NPS-administered parcels and the actual owner/manager rule elsewhere.
Important exceptions: Trail designation is not a detector permission layer and is not a substitute for parcel ownership.

National Forest access is not blanket detector or digging permission. Forest Orders, developed recreation restrictions, wilderness, archaeological/historic resources, active mining claims and the intended target control detector use and recovery.
Important exceptions: Check the ranger district and current Forest Orders; do not disturb archaeological or historic resources and do not interfere with valid mining claims.

USACE detector use is controlled by 36 CFR Part 327, resource-protection rules, and project-specific restrictions. Recreation at a Corps dam/lake does not mean USACE operates every recreation parcel around the reservoir.
Important exceptions: Tri-Lakes USACE explicitly notes it does not operate Cherry Creek State Park, Bear Creek Lake City Park or Chatfield State Park recreation areas; apply the actual recreation manager rule to those parcels. Confirm exact project/zone before searching or digging.

Colorado
CPW states that most participating State Trust Lands are seasonally open for hunting and fishing only, unless specifically authorized for wildlife viewing. A hunting/fishing license or program access does not authorize metal detecting, digging or object recovery.
Important exceptions: Exact property postings and landowner/CPW authorization control; unauthorized use or activity may be enforced.

Jefferson County, Colorado
Jefferson County Open Space states metal detecting is allowed, but participants may not keep found items or disturb a natural surface, except when actively searching for a lost personal item.
Important exceptions: Other park closures, cultural/natural-resource protections and lost-property rules still apply.

National Park Service park areas — 36 CFR §2.1
36 CFR §2.1 prohibits possessing or using metal detectors and related detecting devices in National Park Service park areas. The same section also prohibits digging, disturbing, removing or damaging protected natural, cultural and archaeological resources. current data uses this federal rule only for public visitor/reference points inside identified Florida NPS units; no search-target coordinates are exposed.
Important exceptions: The detector prohibition does not apply when a device is broken down and packed to prevent use, to navigation/safe-operation equipment for boats or aircraft, or to detectors used for authorized scientific, mining or administrative activities. These are not ordinary recreational detecting permissions. Park-specific closures and superintendent rules may be stricter.

U.S. Fish & Wildlife Service National Wildlife Refuge System — 50 CFR Part 27 search/resource restrictions
Federal Refuge System rules provide an A-grade negative decision for antiquity, buried-treasure/treasure-trove, specified mineral-object and prospecting searches and for unauthorized property disturbance/removal. They do not expressly answer every ordinary modern lost-item detector-use scenario. current decision therefore publishes the resolved restrictions while preserving the unresolved narrower detector-use dimension.
Important exceptions: Refuge-specific rules, closures, special-use permits and compatibility determinations may be stricter, including explicit detector prohibitions. Authorized activities may exist under applicable federal regulations. No permission is inferred from public access, beaches, waterways or absence of a refuge-specific detector sentence.
