Rockhounding at Petrified Forest National Park, Arizona
PROHIBITED
Not permitted at this location
Key Conditions
- All collection of petrified wood, fossils, rocks, minerals, and any natural objects is strictly prohibited within Petrified Forest National Park under 36 CFR § 2.1(a)(1)
- 16 U.S.C. § 1866(b) (Petrified Forest Act) specifically prohibits collection of petrified wood from the park
- Even small pieces, fragments, or chips may not be taken — the prohibition covers all natural material regardless of size

Collection is federally prohibited — no exceptions
Petrified Forest National Park prohibits collection of all natural objects under 36 CFR § 2.1(a)(1) and the specific Petrified Forest Act (16 U.S.C. § 1866(b)).
There is no permit, personal-use exemption, or special authorization that allows any collection. This is one of the most clearly and specifically enforced rules in the NPS system — the park exists because of historic over-collection, and rangers take violations seriously.
Taking even a small fragment is a federal offense. Don't.
Petrified Forest National Park preserves one of the world's largest and most colorful concentrations of petrified wood — the mineralized remains of ancient trees from the Late Triassic period, approximately 225 million years ago. The trees fell into flood plains and were buried in volcanic ash-rich sediment, where silica from groundwater replaced the organic material cell by cell over millions of years, creating quartz-crystal wood in vivid reds, oranges, purples, and whites.
The park's specific protection history explains the strictness of current regulations. Before and during early preservation efforts, souvenir collecting removed an estimated 12 tons of petrified wood per year. Congress passed the Petrified Forest Act in 1962 specifically to add explicit legal authority to protect the resource. The damage from historical collection is irreversible — pieces cannot be replaced or regrown.
The practical result for rockhounds: Petrified Forest NP is genuinely one of the most spectacular places in North America to observe fossilized wood, but it is not a place to collect. The legitimate option is to observe, photograph, and purchase legally sourced Arizona petrified wood from shops in Holbrook — approximately 25 miles west on I-40.
Legal petrified wood: Holbrook area shops
Petrified wood from private land outside the park is legally sold throughout the Holbrook, AZ area:
Jim Gray's Petrified Wood Co.: 147 US-180, Holbrook — one of the oldest and largest operations near the park; sourced from private land
Rock shops along I-40: Multiple dealers between Holbrook and Winslow stock privately sourced AZ petrified wood
Legally sourced petrified wood can range from small polished pieces for a few dollars to large whole-log specimens for thousands. This is the appropriate way to own Arizona petrified wood.
How to visit Petrified Forest NP as a rockhound
- 1
Drive the scenic road for scale
The 28-mile park road between I-40 (north entrance) and Hwy 180 (south entrance) passes overlooks of multiple petrified log concentrations. Crystal Forest, Giant Logs, and Long Logs trails all put you near remarkable specimens — observe, photograph, and move on.
- 2
Stop at Crystal Forest
Crystal Forest trail (0.75 mile loop, easy) passes through an extraordinarily dense concentration of quartz-crystal petrified wood logs — many showing brilliant red, purple, and yellow crystalline structure. This is the best single stop for appreciating why the park was protected.
- 3
Visit the Rainbow Forest Museum
The Rainbow Forest Museum at the south entrance has detailed interpretive displays on the taphonomy, mineralization, and geology of the fossil wood. Well worth 30 minutes; provides context for what you're seeing on the trails.
- 4
Note the Painted Desert for minerals context
The Painted Desert section in the northern park is the same Chinle Formation that hosts the petrified wood — iron-oxide and manganese-oxide banding in mudstones creates the vivid colors. Not collectible, but geologically interesting as context for what mineralizing conditions produced the petrified wood.

Shop in Holbrook for take-home specimens
Drive 25 miles west on I-40 to Holbrook, AZ, where privately sourced Arizona petrified wood is sold legally at multiple rock shops. Jim Gray's Petrified Wood Co. on US-180 is the most established. This is how to take home legally obtained Arizona petrified wood.
Permits & Licenses
| Permit | Required? | Notes |
|---|---|---|
| Collection permit | No | No permit for collection exists. The NPS does not issue collection permits to the public for natural objects in national parks. Scientific research permits may be granted to qualified researchers for study of scientific specimens — these are not available to recreational rockhounds under any circumstances. |
Time & Seasonal Restrictions
- Absolutely no collection of petrified wood, fossils, rocks, minerals, or any natural material — regardless of size, location within the park, or stated purpose
- No digging, probing, or disturbing the ground surface
- No use of metal detectors, rock hammers, chisels, or any collection tools
- No removal of cultural artifacts or archaeological materials — criminal penalties under ARPA (16 U.S.C. § 470ee) apply in addition to park regulations
- Photography and observation are the only ways to 'collect' at Petrified Forest NP
Equipment Notes
- Camera or phone with good camera — photography is the appropriate way to document Petrified Forest NP specimens
- Binoculars — useful for viewing specimens that are not on the trail surface
- Trail footwear appropriate for desert conditions — temperatures exceed 100°F in summer; flash flooding in rainy season July–September
- Water — the park has limited facilities; carry at least 2 liters per person for any off-road excursion
- Sun protection — the Painted Desert offers no shade; sun is intense at 5,400-foot elevation
What People Find Here
- Petrified wood — visible throughout the park from the roadside; specimens include entire logs up to 200 feet long and scattered fragments across wide areas of the Chinle Formation
- Painted Desert minerals — iron oxides, manganese oxides, and silica-rich mudstones create the vivid color banding visible throughout; observation only
- Mesozoic fossils — Triassic-era plant and animal fossils including phytosaurs and early dinosaur relatives are present; visible but not collectible
Penalties for Violations
← Scroll to see all columns
| Violation | Statute | Penalty |
|---|---|---|
| Removing petrified wood or any natural object from the park | 36 CFR § 2.1(a)(1); 16 U.S.C. § 1866(b) | Federal offense; fines up to $325 for Class B misdemeanor violations under 18 U.S.C. § 3571; repeat or commercial violations may result in higher fines and potential imprisonment |
| Excavating or removing archaeological objects | Archaeological Resources Protection Act (ARPA), 16 U.S.C. § 470ee | Up to $20,000 fine and 2 years imprisonment for first offense; up to $100,000 and 5 years for subsequent violations |
Etiquette & Leave No Trace
- Leave specimens exactly where you find them — even moving a piece to photograph it from a different angle is technically disturbing park resources
- Report visitors you observe collecting to a ranger — illegal collection is a serious cumulative impact; Petrified Forest lost an estimated 12 tons of petrified wood per year to souvenir collecting before and during early protection periods
- Purchase petrified wood legitimately: privately sourced Arizona petrified wood is sold legally in gift shops throughout the Holbrook area and online — this material comes from BLM or private land outside the park

Frequently Asked Questions
Can I collect petrified wood from Petrified Forest National Park?
No. Collection of petrified wood — or any natural or cultural object — is strictly prohibited within Petrified Forest National Park under 36 CFR § 2.1(a)(1) and the specific Petrified Forest Act (16 U.S.C. § 1866(b)). There is no permit, exception, or personal-use allowance. Taking even a small fragment is a federal offense.
What happens if you take a piece of petrified wood from the park?
Removal of natural objects from national parks is a federal violation. Fines typically start around $325 for a Class B misdemeanor. Rangers actively patrol and check vehicles at park exits. The park also maintains a 'conscience collection' of returned specimens — people mail back pieces they took years or decades earlier, often with notes saying they felt guilty about it. Anecdotal accounts of bad luck following taking park specimens have become a cultural phenomenon, though the practical issue is simply that it's federal law.
Where can I legally collect petrified wood in Arizona?
Petrified wood can be collected legally on BLM land in Arizona within personal-use limits (typically up to 25 pounds per day, 250 pounds per year). Areas near Holbrook outside the park boundary, the Quartzsite area, and other Chinle Formation exposures on BLM land are known collecting localities. Private land with owner permission is also an option — some ranches near Holbrook allow collecting for a fee.
Can I buy petrified wood near the park?
Yes. Petrified wood from private land and BLM sources in Arizona is sold legally throughout the Holbrook area, at highway rock shops on I-40, and online. Legitimate dealers source material from private land or BLM land under permit. This is entirely legal and is how most commercial petrified wood reaches the market.
Does the park have any facilities for rockhounds?
The park has two visitor centers — Painted Desert Visitor Center near the north entrance on I-40, and the Rainbow Forest Museum near the south entrance on Hwy 180 — both with interpretive exhibits on the fossil wood and geology. The Rainbow Forest Museum has excellent displays of intact logs and cross-sections. The park is genuinely worth visiting for observation even though collection is prohibited.
