Fossil Hunting at Grand Staircase-Escalante National Monument, Utah
ALLOWED
No permit required
Key Conditions
- Common invertebrate and plant fossils may be collected for personal non-commercial use under BLM's casual-use fossil policy — up to 25 pounds per day, 250 pounds per year without a permit
- CRITICAL: Vertebrate fossils (bones, teeth, tracks of any backboned animal) may NOT be collected under any circumstances — PRPA prohibits casual collection of vertebrate fossils on all federal land
- Collection must be by surface collection only; no digging, excavation, or use of powered tools
- No collection from scientifically significant areas posted with signs indicating research restrictions — contact BLM Kanab Field Office before collecting in areas with visible recent research activity
- Commercial collection of any fossil material requires a BLM paleontological resources permit
- All collection is for personal non-commercial use; selling BLM personal-use collected fossils is prohibited
The critical rule: invertebrate yes, vertebrate never
Grand Staircase-Escalante (BLM) follows the standard BLM casual fossil collection policy:
Allowed: Common invertebrate and plant fossils — shells, echinoids, ammonites, plant compressions — up to 25 lbs/day, 250 lbs/year, personal use only, surface collection, no permit
Prohibited: All vertebrate fossils — bone, teeth, tracks of any backboned animal — PRPA criminal penalties apply
If you're uncertain whether a specimen is vertebrate or invertebrate: leave it and report to BLM Kanab Field Office at (435) 644-1200
Grand Staircase-Escalante National Monument spans approximately 1.9 million acres of southern Utah between Bryce Canyon and Glen Canyon — the largest national monument in the contiguous United States when it was established in 1996. Unlike most national monuments, it is administered by the Bureau of Land Management rather than the National Park Service, a distinction that matters significantly for fossil collectors.
The monument exposes a nearly complete Cretaceous stratigraphic sequence through a period roughly 95–65 million years ago, representing environments ranging from shallow marine (western portions, older units) to subtropical floodplain forests (eastern portions, younger units). The marine units hold the common invertebrate fossils that casual collectors can legally access. The terrestrial and deltaic units hold the vertebrate material — including the remarkable ceratopsian and hadrosaur assemblages that have made the monument one of the most scientifically important Cretaceous dinosaur sites in North America.
The monument's scale and remoteness mean that most visitor access is through the main highway corridors. Productive fossil collecting typically requires backcountry vehicle access on unpaved roads — high-clearance 4WD is genuinely necessary for most areas of interest, and the nearest services are in the gateway towns of Kanab (south) and Escalante (north).

Reporting vertebrate fossil discoveries
If you observe anything that looks like bone, teeth, or tracks of a vertebrate animal in Grand Staircase-Escalante:
- Do not touch or move it
- Note your precise GPS location
- Photograph it from multiple angles without disturbing the site
- Report to BLM Kanab Field Office: (435) 644-1200
The monument has been the source of major scientific discoveries in the last 20 years — surface-eroding vertebrate material you report may be scientifically significant. BLM staff take these reports seriously and will investigate.
Pre-Trip Checklist — Grand Staircase-Escalante Fossil Hunting
- Review the invertebrate/vertebrate distinction before going — know what you can and cannot legally collect
- Check road conditions with BLM Kanab Field Office (435) 644-1200 — backcountry roads impassable when wet
- Bring high-clearance 4WD vehicle for productive backcountry areas
- Carry minimum 3 liters water per person — no reliable water sources in backcountry
- Download offline topo maps — minimal cell coverage throughout the monument
- Pack out all waste — no facilities in backcountry
- Inform someone of your route and expected return — genuinely remote terrain
Permits & Licenses
| Permit | Required? | Notes |
|---|---|---|
| Personal-use fossil collection permit | No | No permit required for common invertebrate and plant fossil collection under 25 pounds per day, 250 pounds per year. This applies to casual surface collection only. BLM Kanab Field Office: (435) 644-1200. Verify current conditions and any closure orders before visiting — some areas may have temporary research closures. |
| Vertebrate fossil collection permit | Yes | PRPA scientific permits for vertebrate fossils are issued to qualified researchers associated with accredited research institutions only. Not available to the public under any circumstances. If you discover vertebrate fossil material, leave it in place and report it to BLM Kanab Field Office at (435) 644-1200. |
| Commercial paleontological resources permit | Yes | Required for any collection exceeding personal-use limits or intended for sale. Contact BLM Kanab Field Office. |
Time & Seasonal Restrictions
- Vertebrate fossils absolutely prohibited — bones, teeth, scales, claws, and tracks of any backboned animal may not be collected; this is federal law under PRPA regardless of perceived condition or size
- No excavation, digging, or subsurface collection — surface collection only with hand tools
- Personal-use limit: 25 pounds per day, 250 pounds per year for invertebrate and plant fossils
- No collection from posted research areas, active excavation sites, or areas with recent research flags or markers
- Do not remove any material from scientifically significant localities even if it appears to be common invertebrate material — when uncertain, leave it in place
- No vehicles off designated routes — monument terrain is extremely fragile; tracks persist for decades in cryptobiotic soil
- No collection within the developed visitor areas at the Big Water Visitor Center or Cannonville Visitor Center
Equipment Notes
- Hand lens or 10x loupe — useful for examining potential fossil material; Cretaceous marine invertebrates are often small and require magnification for confident identification
- Field guides to Cretaceous marine invertebrates — brachiopods, bivalves, gastropods, echinoids, and ammonites are the primary finds; a paleontology field guide for the Western Interior Seaway is most applicable
- Paper bags or soft cloth for fragile specimens — some Cretaceous shells are friable and require careful transport
- High-clearance 4WD vehicle — essential for backcountry access; most productive fossil areas are on unpaved roads that require 4WD; passenger vehicles limited to main paved routes
- Water (minimum 3 liters per person), sun protection, and emergency supplies — the monument is genuinely remote; nearest services are in Kanab, Escalante, or Big Water
- Detailed topo maps and GPS — the monument has minimal signage in backcountry areas; navigation without maps is not advisable
What People Find Here
- Marine bivalves and brachiopods — from Cretaceous (Cenomanian–Campanian) marine formations; relatively common surface finds in appropriate formation outcrops
- Ammonite fragments — occasional; Cretaceous Western Interior Seaway ammonites occur in the marine units; complete specimens rare, fragments more common
- Echinoid (sea urchin) tests and spines — Cretaceous marine units; occasional surface finds
- Plant compression fossils — from terrestrial and brackish-water formations; leaf and wood impressions in mudstone and siltstone
- Oyster and other large bivalve shells — massed accumulations in some Cretaceous limestone beds
- Note: the famous ceratopsian, hadrosaur, and tyrannosaur fossils found at Grand Staircase (Diabloceratops, Kosmoceratops, Machairoceratops, etc.) are vertebrate material — all prohibited
Penalties for Violations

| Violation | Statute | Penalty |
|---|---|---|
| Casual collection of vertebrate fossil material | PRPA (16 U.S.C. § 470aaa-9) | Federal felony; fines up to $100,000 and up to 2 years imprisonment for first offense; civil penalties additionally available |
| Exceeding personal-use limits for invertebrate fossils or commercial collection without permit | PRPA (16 U.S.C. § 470aaa-8); BLM Regulations | Federal violation; fines and permit disqualification |
| Off-route vehicle travel in monument | BLM Grand Staircase-Escalante Management Plan; 43 CFR Part 8340 | Federal violation; fines; vehicle impoundment |
Etiquette & Leave No Trace
- Understand the invertebrate/vertebrate distinction before you go — the single most important rule is that any fossil with a backbone (bone, tooth, track) is off-limits; common marine invertebrates (shells, echinoids) are legally collectible
- If you find something you believe may be vertebrate material — any bone-like, tooth-like, or track-like material — leave it exactly in place and report to BLM Kanab Field Office (435) 644-1200
- Avoid driving or walking on cryptobiotic soil crust — the dark, bumpy soil surface in dry areas of the monument is a living biological crust that takes decades to recover from a single footstep; stay on rocks and bare soil where possible
- Pack out all waste — there are no facilities in most of the monument's backcountry; pack-in, pack-out applies strictly
- Don't remove fossils from scientifically significant context to improve your specimen without understanding the implications — a marine shell in matrix with clear stratigraphic position has scientific information; removed from context, it has only aesthetic value

Frequently Asked Questions
What fossils can I legally collect at Grand Staircase-Escalante?
Common invertebrate and plant fossils may be collected for personal use under BLM's casual-use fossil policy — up to 25 pounds per day. This includes marine shells (bivalves, brachiopods, oysters), echinoid material, ammonite fragments, and plant compressions from appropriate formation outcrops. Vertebrate fossils — any fossil from a backboned animal — are prohibited regardless of apparent size or condition.
How do I tell the difference between a vertebrate and invertebrate fossil?
Invertebrate fossils at Grand Staircase typically include shells (clamlike shapes, spiral gastropods, rounded echinoid tests), branching coral or bryozoan structures, and leaf impressions. Vertebrate fossils include anything resembling bone (irregular, often with visible internal texture like cancellous structure), teeth (dense, often smooth or striated), or tracks (foot impression shapes with digit marks). When in doubt — leave it in place and report it. The BLM Kanab Field Office can help with identification: (435) 644-1200.
Why is Grand Staircase famous for dinosaur fossils if I can't collect them?
The monument's Cretaceous formations have yielded some of the most important Late Cretaceous dinosaur discoveries of the past 30 years — including multiple new ceratopsian species (Diabloceratops, Kosmoceratops, Machairoceratops), new hadrosaurs, and a new tyrannosaur. These are significant vertebrate fossils collected under PRPA scientific permits by research teams from the Natural History Museum of Utah and other institutions. They represent exactly the type of discovery that PRPA was designed to protect — vertebrate material that can only be properly studied under scientific protocols, not casual collection.
Do I need a 4WD vehicle to fossil hunt at Grand Staircase-Escalante?
For most productive fossil areas, yes. The main paved road (Hwy 12 through Escalante, and US-89 along the southern boundary) are accessible to all vehicles, but the backcountry roads where Cretaceous outcrops are most accessible require high clearance and 4WD, particularly after precipitation. The Cottonwood Canyon Road, Hole-in-the-Rock Road, and Smoky Mountain Road provide backcountry access but require appropriate vehicles. Contact BLM Kanab Field Office for current road conditions before heading in.
What formations produce the collectible invertebrate fossils?
The Tropic Shale, Straight Cliffs Formation, and Wahweap Formation contain marine and brackish-water invertebrate fossils from the Cretaceous Western Interior Seaway. The Tropic Shale (grayish mudstone) is particularly productive for bivalves, brachiopods, and occasional ammonites. These units are exposed throughout the monument's lower elevation areas, particularly in the southern and eastern portions. The BLM Kanab Field Office can provide formation maps and current access information.
