No, you cannot take a rock from a national park. Doing so violates federal regulation 36 CFR 2.1, which prohibits removing, disturbing, or possessing any natural object inside a park unit. Penalties reach $5,000 in fines and up to six months in jail, and a handful of narrow exceptions exist only where a park superintendent has specifically authorized collection.1eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources2Office of the Law Revision Counsel. 18 USC 1865 – National Park Service
What the Rule Actually Prohibits
36 CFR 2.1 makes it illegal to remove, damage, deface, dig up, or disturb from its natural state any of the following inside a park:1eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources
- Rocks and minerals, from trailside pebbles to river boulders.
- Plants and plant parts, including flowers, branches, pinecones, and driftwood.
- Fossils, whether fossilized or not.
- Cultural and archaeological objects such as arrowheads and pottery shards.
- Cave formations, including stalactites and stalagmites.
The same regulation bans using a metal detector or magnetometer anywhere inside park boundaries. You may transport one through a park only if it is broken down and packed so it cannot be operated.1eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources
Size does not matter under the rule. A single pebble is covered by the same text as a boulder. The National Park Service operates under a statutory mandate to leave park resources “unimpaired for the enjoyment of future generations,” and the regulation is written to match.3Office of the Law Revision Counsel. 54 USC 100101 – Promotion and Regulation
Fines and Jail Time
Under 18 U.S.C. § 1865, violating a National Park Service regulation can bring imprisonment of up to six months, a fine, or both.2Office of the Law Revision Counsel. 18 USC 1865 – National Park Service That six-month maximum makes the offense a Class B misdemeanor under federal law.4Office of the Law Revision Counsel. 18 USC 3559 – Sentencing Classification of Offenses The maximum fine on a Class B misdemeanor is $5,000 for an individual.5Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
Where a case lands within that range depends on what you took and how a ranger or prosecutor reads the conduct. A pocketed pebble might mean a citation and a modest fine. Something rarer pushes toward the top of the scale. Some parks also have their own minimum penalties: at Petrified Forest National Park, removing any petrified wood carries a minimum fine of $325.6National Park Service. Laws and Policies – Petrified Forest National Park
Criminal fines are not always the end of the exposure. Federal natural resource trustees can pursue restoration and repair costs, plus the compensable value of lost public use while a site recovers. For meaningful damage, those civil costs can exceed the criminal fine.
When That “Rock” Is a Fossil or Artifact
The penalties get much steeper if the object turns out to be a fossil or a piece of human history. Two additional federal laws sit on top of the standard park regulation.
The Paleontological Resources Preservation Act covers fossils on any federal land. A knowing violation can bring up to five years in prison and fines under Title 18. If the combined commercial and paleontological value plus restoration cost is under $500, the ceiling drops to two years. Repeat offenders face doubled penalties.7Bureau of Land Management. Paleontological Resources Preservation Act
The Archaeological Resources Protection Act covers any material remains of human activity at least 100 years old.8eCFR. 43 CFR 7.3 – Definitions A first offense can mean up to $10,000 and one year in prison. If the archaeological value and restoration cost exceed $500, the cap rises to $20,000 and two years. A second or later violation can reach $100,000 and five years.9Office of the Law Revision Counsel. 16 USC 470ee – Prohibited Acts and Criminal Penalties
Both statutes also criminalize selling, transporting, or buying items you know were taken illegally. The Lacey Act adds another layer, making it a federal offense to sell, transport, or receive plants or wildlife taken in violation of any federal, state, or tribal conservation law. Listing a park-taken fossil on a resale site can trigger charges on top of the original removal.
The Narrow Exceptions
A few activities are allowed, but only where a superintendent has specifically designated them. Nothing is legal by default just because it feels harmless.
Shells, Berries, and Nuts
Under 36 CFR 2.1(c), a superintendent may designate certain fruits, berries, nuts, or unoccupied seashells for hand-gathering for personal use, but only after finding the activity will not harm wildlife, plant reproduction, or other resources.1eCFR. 36 CFR 2.1 – Preservation of Natural, Cultural and Archeological Resources The superintendent also sets quantity limits, locations, and whether items can leave the park. Selling anything you gather is prohibited.
This mostly plays out at national seashores. Cape Lookout allows up to five gallons of empty shells per person per day.10National Park Service. Shelling – Cape Lookout National Seashore Cumberland Island permits two gallons of uninhabited shells and fossilized shark teeth per person per day.11National Park Service. Beachcombing Shells with a living creature inside stay on the beach.
Most Alaska Parks
Most national parks in Alaska allow surface collection of rocks and minerals by hand for personal recreational use. Shovels, pickaxes, sluice boxes, and dredges are not allowed, and silver, platinum, gemstones, and fossils remain off limits. The exception does not apply at Klondike Gold Rush National Historical Park, Sitka National Historical Park, the former Mt. McKinley National Park area, or the former Katmai National Monument area.12eCFR. 36 CFR 13.35 – Preservation of Natural Features
A Few Park-Specific Carve-Outs
Whiskeytown National Recreation Area in California permits limited gold panning. Pipestone National Monument in Minnesota authorizes American Indian collection of catlinite, the red pipestone used for ceremonial pipes.13National Park Service. Recreational Collection of Rocks and Minerals – Legal Instruments Where a park has no published rule allowing collection of a specific resource, the default ban applies.
Can You Just Mail It Back?
Petrified Forest National Park regularly receives packages of returned rocks with apologetic notes, some blaming guilt and others a run of bad luck. The park keeps them, but it cannot put them back on the landscape: no one knows where each piece originally sat, and that geological context matters for research.
Returning an item does not undo the original violation. Whether you would face prosecution after a voluntary return is a matter of circumstance and law enforcement discretion. The park gains little from a rock with no provenance, and you gained nothing by taking it.
Other Federal Land Follows Different Rules
Park rules are stricter than the rules on most other federal land. Assuming they all match is the mistake that turns a legal hobby into a federal citation.
The Bureau of Land Management allows the public to collect reasonable amounts of rocks, mineral specimens, and semiprecious gemstones for personal, noncommercial use without a permit. Collection is off limits at developed recreation sites, active mining claims, and lands where the mineral estate is privately owned.14Bureau of Land Management. Rockhounding on Public Lands15Bureau of Land Management. Public Collection of Rocks, Mineral Specimens, and Semiprecious Gemstones FAQs Petrified wood on BLM land has a specific cap: up to 25 pounds plus one piece per day, with an annual limit of 250 pounds per person, and no pooling of quotas.16GovInfo. 43 CFR Part 3620 – Free Use of Petrified Wood
The U.S. Forest Service permits limited collection of common, low-value rocks and minerals for personal hobby use on many National Forest System lands without a permit, generally up to about 10 pounds. The material cannot be sold or bartered.17USDA Forest Service. Collecting on National Forest Service Lands
National wildlife refuges follow a ban similar to national parks. Removing any natural object from a refuge is illegal, regardless of how undeveloped it looks.18eCFR. 50 CFR 27.61 – Destruction or Removal of Property Before pocketing anything on public land, confirm which agency manages the ground you are standing on. Boundaries between park, forest, BLM, and refuge land are often marked lightly, and the legal consequences of guessing wrong all run in the same direction.
