Fossil hunting in Utah: trilobites, fossils and meteorites
Where can you go fossil hunting in Utah? Start with trilobites. In the House Range west of Delta, the Wheeler Shale gives up thousands of them every year, and you can split the shale yourself at two family-run quarries or on the public land around them. Beyond the trilobites there are the Ordovician seashells and crinoids of Fossil Mountain, oyster beds near Caineville, petrified wood on BLM land, and two meteorite areas in the open desert. Dinosaur bones are another story: at Dinosaur National Monument and Jurassic National Monument you can look, but never take. Below: where to go, what you can keep, how to search, the famous sites you can only visit, and the clubs that can take you there.
Where you can dig and take it home
Utah has some of the most famous fossil sites on Earth, but most of its dinosaur country is in national parks, national monuments, state parks or on tribal and private land, where you can only look. These are the places we've checked one by one where you can legally collect and keep what you find:
- 21 fossil spots on public land with no active mining claim.
- 3 fossil spots on public land with a possible mining claim: check the claim and ask the holder before you dig.
- 39 meteorite spots on BLM land inside known meteorite areas, with no active mining claim.
- 2 meteorite spots on BLM land inside known meteorite areas, with a possible mining claim: check the claim and ask the holder before you dig.
- 2 dig sites set up for visitors, where you dig and keep what you find.
- 1 public collecting area set aside by the land agency for visitors.
- 10 clubs that run fossil and meteorite trips, the easiest way into places you can't reach alone.
Bones and teeth (vertebrate fossils) are protected on federal land: there, leave them in place and report them. Elsewhere the rules depend on the landowner: each site page says what applies.

Where to find fossils in Utah
- House Range, west of Delta: Cambrian trilobites at Antelope Springs, at the two pay quarries and on the public land around them.
- Fossil Mountain and the Confusion Range, Millard County: Ordovician shells and trilobites, horn corals, crinoids and ammonites.
- Caineville, Wayne County: beds packed with fossil oysters (Pycnodonte newberryi), plus agate, jasper and petrified wood along Highway 24.
- Price and the San Rafael country: fossil clams and cephalopods, plant fossils with coal, agate and petrified wood.
- Petrified wood on BLM land near St. George and in the canyon country: up to 25 pounds a day plus one piece.
- Northern Utah: horn corals west of the Great Salt Lake, fossil-bearing concretions in Rich County and fossil plants in Utah County.
- Most of these spots come from the Utah Rockhounder, the collecting map of the Utah Geological Survey and the BLM. We checked each one against land ownership and left out everything inside parks, monuments, wilderness areas and tribal land.
Where to find trilobites in Utah: the House Range
About 505 million years ago, western Utah lay under a shallow sea. Its muddy floor became the Wheeler Shale, and it kept trilobites by the million. The classic spot is Antelope Springs, in the Wheeler Amphitheater of the House Range, about 50 miles west of Delta. The most common trilobite there is Elrathia kingii, usually under an inch long; with luck you'll also find the larger Asaphiscus wheeleri, tiny eyeless agnostids and small brachiopods.
Two family-run quarries work the trilobite layers: U-Dig Fossils, run by a family that has collected trilobites here for generations, and A New Dig, just up the road, where you dig by reservation and an excavator brings up fresh shale. You pay, split the rock with a hammer and keep what you find. The BLM land around Antelope Springs is open to collecting too, and we have mapped the public spots described by the Utah Geological Survey.
Long before collectors arrived, the native people of this desert picked up trilobites here and wore them as amulets. Today the House Range supplies many of the trilobites sold in rock shops around the world.
Fossil Mountain and the Confusion Range
South-west of the trilobite quarries, the slopes of Fossil Mountain expose seabed rocks from the Ordovician, about 485 to 458 million years old, crowded with brachiopods, trilobites, cephalopods, gastropods, sponges, graptolites and echinoderms. The mountain was named by Frank Beckwith of Delta, who explored the West Desert and promoted it to fossil collectors, and in the 1930s University of Utah geology students came here on regular field trips.
Today Fossil Mountain sits inside the King Top Wilderness Study Area. The BLM allows collecting reasonable amounts of common invertebrate fossils, but only from the surface: no digging, and no vehicles past the end of the road. Walk the wash on the north side and the lower slopes, where fossils weather out of the hillside on their own.
The ranges around it hold more: horn corals, crinoids, brachiopods and ammonites in the Confusion Range, and more Ordovician brachiopods and trilobites around Ibex. A few of those spots sit on state trust land, where you need the $25 SITLA permit, and the card on the map tells you which.
Where to find crinoid fossils in Utah
- Fossil Mountain, Millard County: the Utah Geological Survey lists crinoids among the easiest fossils to find there, together with brachiopods, gastropods, cephalopods and trilobites. Look in the loose rocks on the slopes: collectors report better pieces higher up the hill. Surface collecting only, because the mountain is inside a wilderness study area.
- The Confusion Range around Fossil Mountain: crinoids turn up with horn corals, brachiopods and ammonites. The horn corals there date from the Mississippian, about 340 million years ago.
- Southern Utah: small star-shaped pieces in the rock are stem plates of Isocrinus, a five-sided crinoid that lived in a shallow sea that reached Utah from the north about 170 million years ago, in the Middle Jurassic.
- Crinoids are relatives of starfish that lived anchored to the sea floor on a long stem. Most fossil crinoids turn up as pieces of that stem.
Meteorites in Utah: where they've been found
Utah has 28 meteorites in the official record of the Meteoritical Society. The biggest is the Drum Mountains iron, 529 kilograms, found near Delta in 1944 and the ninth heaviest meteorite ever found in the United States. Most of the others are single finds scattered across the state, and we don't put markers on single finds.
The Tule Valley Hardpan, a dry lake about 50 miles west of Delta, is different: nine meteorites from different falls were found on the same stretch of bare clay between 2001 and 2014, two of them during a BYU geology club outing. They are small, from about 1 to 37 grams, and one is a rare enstatite chondrite. Fossil Mountain is a few miles to the south, so you can do both in one trip.
On August 13, 2022, a daytime fireball crossed northern Utah and sonic booms shook the Salt Lake Valley: the first witnessed meteorite fall in Utah since Garland in 1950. Doppler weather radar tracked the falling stones to the south end of the Great Salt Lake, and within weeks hunters had recovered more than a dozen pieces, the largest about 780 grams. The big pieces are gone, but the radar showed fragments down to a fraction of a gram. Part of the fall zone is open BLM land; the lake bed and shoreline are state land, where collecting is not allowed.
How we built the zones: for each area we take the meteorites registered with the Meteoritical Society, draw a circle of about 1.2 miles around each find, keep only the open BLM land inside it, and place a marker about every 0.6 mile. A marker shows where meteorites have been found, not where one is waiting for you: the odds on any given day are low, but patient hunters still turn up the odd stone.
How to hunt fossils and meteorites in Utah
- Trilobites: bring a flat-edged rock hammer and split the shale along its layers. Fresh, unweathered rock gives the best pieces. Wrap your finds in paper towels: the shale is fragile.
- Fossil Mountain and other wilderness study areas: pick up what lies on the surface and leave the hillside as you found it.
- Meteorites: walk slowly with a metal detector, or scan bare ground by eye for dark, heavy stones with a thin black or rusty crust. Most meteorites stick to a magnet. Record the exact GPS point of any find: without it, a meteorite can't be properly registered.
- Spring and fall are the best seasons. West Desert summers are hot, and winters can be bitterly cold.

Famous dinosaur sites in Utah you can visit but not dig
At Dinosaur National Monument, near Jensen, the Quarry Exhibit Hall is built right over the hillside where Earl Douglass found dinosaur bones in 1909. About 1,500 bones are still in the rock, from Allosaurus, Stegosaurus and the long-necked giants, exactly where a Jurassic river left them. In September 2025, crews repaving the parking lot uncovered new bones, the first dug at the quarry since 1924. It's run by the National Park Service, and nothing may be collected, not even a chip of rock. For fossils you can keep, head west to the trilobite quarries of the House Range.
Jurassic National Monument, south of Price, protects the Cleveland-Lloyd Dinosaur Quarry, the densest concentration of Jurassic dinosaur bones ever found: more than 12,000 bones from at least 74 animals, most of them Allosaurus, Utah's state fossil. The BLM runs a small visitor center and trails there, but the bones are protected. Around Price, open BLM land has fossil clams, ammonites, plant fossils and petrified wood you may collect, and several of those spots are on our map.
North of Moab, the Mill Canyon Dinosaur Tracksite shows more than 200 tracks and traces, about 112 million years old, left by at least ten kinds of animals, from sauropods to a crocodile that slid across the mud. Stay on the boardwalk: even walking on the tracks damages them, and tracks are vertebrate fossils that no one may collect.
Escalante Petrified Forest State Park has trails through logs of petrified wood. Taking anything out of a state park is illegal, and over the years the park has collected dozens of letters from visitors who mailed their stolen wood back, blaming it for a run of bad luck. Petrified wood on open BLM land is a different story: you may collect it within the federal limits, and we have mapped spots near St. George and in the canyon country.
Grand Staircase-Escalante National Monument keeps producing new dinosaurs for Utah's museums, but it's a national monument, and we leave it off our map. Before you go out, see the real thing at the Natural History Museum of Utah in Salt Lake City, the Utah Field House of Natural History State Park Museum in Vernal or the Prehistoric Museum in Price.
Staying safe while fossil hunting in Utah
- The West Desert has no services: fuel up in Delta, carry plenty of water and a spare tire.
- Phone signal drops in the mountains: download your maps and print your directions before you leave.
- Never drive onto a hardpan or salt flat when it's damp: you can get stuck far from help.
- The last miles to Fossil Mountain are rough: high clearance or four-wheel drive is recommended.
- Watch the sky: a summer storm can turn a dry wash into a river in minutes.
Utah fossil curiosities and the state fossil
- Utah's state fossil isn't a trilobite: it's Allosaurus, chosen in 1988. In 2018 Utahraptor became the state dinosaur.
- Clay Holman, owner of A New Dig, found an animal new to science in his quarry, and Harvard paleontologists named it Thelxiope holmani after him.
- Garland, Utah's only witnessed fall before 2022, was a diogenite: a small piece of the asteroid Vesta.
- Great Salt Lake meteorite hunters arrived from Nevada, Arizona and California within days of the fireball: the first stone, 217 grams, was picked up three days after the fall.
Questions we often get
Is it legal to collect fossils in Utah?
On BLM land, yes: common invertebrate and plant fossils, like trilobites, shells and leaf imprints, in reasonable amounts for your own collection, up to 25 pounds a day plus one piece and 250 pounds a year. Selling them is not allowed. In the national forests, limited personal collecting of the same kinds of fossils is generally allowed, but check with the local ranger district. On state trust land you need a SITLA rockhounding permit. National parks, state parks and tribal land are off limits, and on private land you need the owner's permission.
Where can I find trilobites in Utah?
In the House Range west of Delta, around Antelope Springs. U-Dig Fossils and A New Dig let you dig in the Wheeler Shale for a fee and keep what you find, and the BLM land around them is open to collecting. Fossil Mountain, to the south-west, has Ordovician trilobites too, surface collecting only.
Where can I find crinoid fossils in Utah?
Fossil Mountain in Millard County is the easiest place: crinoids are among the most common fossils in the loose rocks on its slopes, and the BLM allows surface collecting of reasonable amounts. The Confusion Range around it has crinoids too, and in southern Utah you can find the star-shaped stem plates of Isocrinus, a Middle Jurassic crinoid.
Do I need a permit to collect on Utah state trust land?
Yes. Trust land is not public land: you need a SITLA rockhounding permit, $25 a year for an individual or family. It allows hand collecting of up to 25 pounds plus one piece a day and 250 pounds a year, for personal use only, and never vertebrate fossils. It doesn't cover trust land under a mineral lease, land posted closed to rockhounding, or other state land such as state parks.
Can I collect petrified wood in Utah?
On BLM land, yes: up to 25 pounds a day plus one piece, and no more than 250 pounds a year, for personal use. Not in Escalante Petrified Forest State Park or in any national park.
Can I keep a meteorite I find in Utah?
On BLM land, yes: you can collect meteorites on the surface, with a metal detector but no motorized or mechanical tools, up to 10 pounds per person per year, for personal use only, with no selling or trading. The bed and shoreline of the Great Salt Lake are state land, where collecting is not allowed, and on private land a meteorite belongs to the landowner.
Can I collect fossils at Dinosaur National Monument?
No. Collecting anything in a place run by the National Park Service is illegal, and the bones at Jurassic National Monument are protected too. Dinosaur bones, teeth and tracks can't be collected anywhere on public land in Utah without a research permit.
What if I find a dinosaur bone, tooth or track?
Leave it where it is. Vertebrate fossils can't be collected on any federal or state land in Utah except under permits issued to museums and universities. Take photos, note the GPS point and report it to the land manager or the Utah Geological Survey.
Can I collect fossils at Fossil Mountain?
Yes: reasonable amounts of common invertebrate fossils for personal use, but only from the surface. Fossil Mountain is inside the King Top Wilderness Study Area, so no digging and no vehicles past the end of the road.
