Is rockhounding legal? Rock collecting rules by type of land

Updated October 20, 2026. Rules come from federal regulations and agency guidance; sources are at the end of the page. This is a guide, not legal advice.

Depends on who manages the land

Yes, in many places, but it depends on who manages the land. On most Bureau of Land Management land you may collect reasonable amounts of rocks, minerals and semiprecious gemstones for noncommercial use without a permit. National parks prohibit it, national forests set their own rules, and mining claims and private land need the owner’s permission.

BLM public land: Yes: reasonable amounts for personal use, usually no permit
National forests: Rules differ by forest; check first
National parks: No: collecting is prohibited
Mining claims: Only with the claim holder’s permission

The rules by type of land

Land	Can you collect?	The main rule
BLM public land	Yes	Reasonable amounts of rocks, mineral specimens and semiprecious gemstones for noncommercial use, usually without a permit. Not on developed recreation sites, closed or posted areas, active mining claims or land where the mineral rights are private.
BLM national monuments	Usually	Generally yes for noncommercial use, except rocks named as monument objects in the monument’s proclamation. A 2014 BLM Arizona brochure says the opposite for Arizona monuments, so check the specific monument.
BLM wilderness	Usually	Generally yes, with non-motorized hand tools and minimal surface disturbance, following the area’s management plan.
National forests	Check the forest	The Forest Service regulation prohibits removing natural features unless allowed, and each forest sets its own collecting rules. Ask the ranger district before you collect.
National parks	No	Removing minerals is prohibited in all units of the National Park System, and violators face criminal penalties.
Mining claims	Only with permission	Collecting on a claim is prohibited without the claim holder’s permission.
Private land	Ask the owner	Check who owns the land before a trip and ask the owner first.

BLM land in detail

What you can take: reasonable amounts of rocks, mineral specimens and semiprecious gemstones, including gold, silver and other precious metals, for personal use.
Tools: hand tools such as pans, shovels and metal detectors. No explosive, motorized or mechanical devices without authorization.
When you may need a permit: if you use certain equipment, cause more than negligible surface disturbance, or camp or stay longer than posted.
Closed areas: collecting is prohibited where the BLM formally closes an area, and doing it anyway can bring criminal or civil penalties.
Arizona numbers: BLM’s 2014 Arizona brochure defines a reasonable amount as up to 25 pounds a day and 250 pounds a year. National BLM rules give no pound figure, so other states may differ.

Petrified wood

Daily limit: 25 pounds plus one piece per person.
Yearly limit: 250 pounds per person per calendar year, and no pooling of quotas to get bigger pieces.
Big pieces: a specimen over 250 pounds needs a permit.
Tools: no explosives or power equipment.
Personal use only: it may not be sold or bartered to commercial dealers.
National parks: none at all, including Petrified Forest. See national parks.

Fossils

Common invertebrate and plant fossils, such as trilobites and shells: a reasonable amount for non-commercial personal use on BLM, Bureau of Reclamation and Forest Service land, from the surface or with non-powered hand tools.
Vertebrate fossils (dinosaurs, reptiles, fish, birds, mammals): only with a permit, issued to qualified people for research or education. Fossils collected under a permit stay the property of the United States.
Other federal land, such as national parks: the casual-collecting exception does not apply, so a permit is required.

Where to look: fossil hunting near me.

Artifacts and arrowheads

Leave them in place. Removing archaeological resources from public or Indian land is prohibited without a permit.
Arrowheads count. BLM rules list arrowheads, flakes, pottery and old bottles among the things you may not collect.
Penalties: up to $10,000 and one year in prison for a first violation, up to $20,000 and two years when the value and repair cost exceed $500, and up to $100,000 and five years for a repeat violation.
Ordinary rocks are not artifacts. The artifact law does not cover collecting rocks or minerals that are not archaeological resources.

Mining claims

Ask first. The BLM says collecting on a mining claim is prohibited without the claim holder’s permission, and claimants may have the right to exclude others.
How to check: look the area up in the BLM’s MLRS reports or its research map before you go.

Selling what you collect

Casual collecting is for personal use. The BLM defines noncommercial as “not selling the items for a business or financial gain”.
Collecting to sell or barter to commercial dealers needs a contract or permit from the BLM.
Petrified wood collected for free may not be sold or bartered to commercial dealers.
Fossils: the BLM does not authorize commercial use of fossils collected on public lands.

State rules in the West

Arizona State Trust Land is not public land: according to BLM’s 2014 Arizona brochure, rockhounding and metal detecting are not allowed there, and a state Recreational Use Permit is needed even to camp, hike or travel on it. We could not check the state agency’s own page.
California state parks: removing rocks and minerals is prohibited, except rockhounding where state rules specifically permit it.
Oregon ocean shore: agates, stones, shells and fossils loose on the ground, in small amounts for personal use: no more than a one-gallon container per person per day and three gallons per year, each person with their own container.
Nevada state parks and lands: we could not verify the rules yet. Ask the park before you collect.

Questions

Is rockhounding legal?

It depends on who manages the land. On BLM public land you may collect reasonable amounts of rocks, mineral specimens and semiprecious gemstones for noncommercial purposes, except on developed recreation sites, closed or posted areas, active mining claims and land with private mineral rights. In national parks, removing minerals is prohibited. National forests set their own rules.

Do I need a permit to collect rocks on BLM land?

Generally no, for reasonable amounts for noncommercial purposes. The BLM says you may need one if you use certain equipment, cause more than negligible surface disturbance, or camp or stay longer than posted. Collecting for sale or barter to commercial dealers needs a contract or permit.

How much petrified wood can I take from BLM land?

25 pounds plus one piece per person per day, and no more than 250 pounds per calendar year. Pooling quotas for bigger pieces is not allowed, specimens over 250 pounds need a permit, and explosives and power equipment are banned.

Can I sell rocks I collected on public land?

Not rocks you collected for free under the casual-use rules. The BLM defines noncommercial as not selling the items for a business or financial gain, petrified wood may not be sold or bartered to commercial dealers, and collecting for sale needs a contract or permit.

Can I keep fossils or arrowheads I find?

Common invertebrate and plant fossils: yes, a reasonable amount for non-commercial personal use on BLM, Bureau of Reclamation and Forest Service land, collected from the surface or with non-powered hand tools. Vertebrate fossils need a permit issued to qualified applicants. Artifacts, including arrowheads, must be left in place.

Can I collect on a mining claim, and how do I check for claims?

The BLM says collecting on a mining claim is prohibited without the claim holder’s permission. You can look up claims in the BLM’s Mineral & Land Records System reports and research map.

Can I rockhound in a national monument or wilderness area?

In BLM national monuments, generally yes for noncommercial purposes, unless the rocks are named as monument objects or the area is closed; a 2014 BLM Arizona brochure says otherwise for Arizona, so check the specific monument. In BLM wilderness, only non-motorized hand tools and minimal surface disturbance are allowed.
