Rockhounding at Quartzsite, Arizona (BLM Open Desert)
ALLOWED
No permit required
Key Conditions
- BLM Arizona allows up to 25 lb per day and 250 lb per year of rocks and minerals for personal, non-commercial use, no permit required. The federal rule (43 CFR § 8365.1-5(b)(2)) says only "reasonable amounts"; the numbers are BLM Arizona's
- Active and patented mining claims exist throughout the Quartzsite area — collecting on a valid claim without claim holder permission is a federal violation; check BLM's MLRS before collecting in any specific area
- La Posa Long Term Visitor Area (LTVA) is approximately 11,400 acres of BLM-managed desert open to casual rockhounding
- Kofa National Wildlife Refuge to the south is closed to collecting except the 1.5-square-mile Crystal Hill Area (10 specimens or 10 lb a year, no tools)
- Hand tools only; no motorized excavation. In the New Water Mountains Wilderness, collecting is still allowed but only with non-motorized hand tools and minimal surface disturbance

Quartzsite's most common rockhounding mistake is a boundary one, not a weight one. Drive south on US-95 and the open BLM desert gives way to Kofa National Wildlife Refuge, where the U.S. Fish & Wildlife Service bans rock collecting everywhere except the 1.5-square-mile Crystal Hill Area, and even there you may take only 10 specimens or 10 pounds a year, by hand, with no digging. The BLM ground around town is far more generous: BLM Arizona's brochure sets personal use at 25 pounds a day and 250 pounds a year, with no permit (the federal rule and other states' figures are compared in our BLM personal-use collecting guide).
The other complication is claims. The Plomosa Mountains east of town are an old placer gold district, described by the USGS a century ago, and placer and lode claims still sit across the washes. A claim holder has the exclusive right to possess the claim surface (30 U.S.C. § 26), and BLM's own FAQ says collecting is generally not allowed on active claims. The broad La Posa Plain around the LTVA is the easy starting point; anything in the foothills needs a claim check first. For how Quartzsite fits with the rest of the state, including the State Trust land trap, see the Arizona rockhounding overview.
Mining claims — check before you collect
The Quartzsite area has one of the highest densities of staked mining claims on any BLM land in Arizona. A valid mining claim gives the claim holder exclusive rights to mineral extraction — collecting on a claim without permission is a federal violation even if the land is otherwise BLM public land.
Before collecting in any specific wash or hillside area:
- Check the BLM MLRS Research Map at mlrs.blm.gov/s/research-map for the township/range/section
- Look for physical claim markers (wooden posts, rock monuments, notices)
- When in doubt, move to an area with confirmed open status or call the Yuma Field Office: (928) 317-3200
The open La Posa Plain surface-scatter areas are generally unclaimed but verifying is always the right move.
The 25 lb/day federal casual-use rule explained
43 CFR § 8365.1-5(b)(2) is the federal regulation that allows recreational collecting of rocks, minerals and gemstones on BLM public land without a permit, in "reasonable amounts". It sets no weight. BLM Arizona turns that into two limits:
- Daily limit: 25 lbs per person per day
- Annual limit: 250 lbs per person per year
These limits apply to personal, non-commercial use only. Selling, trading, or commercially guiding collecting trips requires a separate BLM minerals permit. The rule does not apply to:
- Vertebrate fossils (require a research permit under PRPA 2009)
- Archaeological artifacts (protected under ARPA regardless of quantity)
- Areas under valid mining claims
Designated BLM wilderness isn't closed to collecting, but you're limited to non-motorized hand tools and minimal surface disturbance there.
25 lbs is approximately a medium-sized daypack — a limit that is rarely a practical constraint for casual rockhounders.

Best Times to Rockhound at Quartzsite
Winter (Nov–Feb)
GoodPeak season. The January–February gem and mineral shows (Tyson Wells opens the season in early January) bring the biggest crowds of the year. Weather is ideal (55–75°F days). All BLM areas at full access. Most rockhounds plan their visit around the shows. Competition for the best surface-scatter spots is at its highest during show weeks.
Spring (Mar–May)
GoodCrowds drop off significantly after the shows. Weather remains excellent through April. Spring wildflower blooms make the desert particularly scenic. Good window for less-crowded collecting.
Summer (Jun–Sep)
PoorNot recommended. Quartzsite regularly records temperatures above 110–115°F from June through August. Flash flood risk from monsoon rains (July–September). Some BLM roads become impassable after rain. Emergency services response times are very long in the open desert. Avoid unless you have desert-expedition experience and reliable 4WD with recovery equipment.
Fall (Oct–Nov)
FairTemperatures moderate through October (85–95°F). Monsoon season ends by mid-October. Crowd levels low — good opportunity for unhurried surface collecting before winter show season begins.
How to Plan a Quartzsite Rockhounding Trip
- 1
Identify target minerals and areas
The La Posa Plain around the LTVA, reached from the US-95 / I-10 interchange, is the easiest starting point. For placer gold or copper minerals you'll be in the Plomosa Mountains washes, where claims are densest, so plan the claim check below before you go.
- 2
Verify mining claim status
Use BLM MLRS (mlrs.blm.gov/s/research-map) to search by township/range for your target area. The Yuma Field Office can also advise: (928) 317-3200. This step is especially important if collecting away from the standard tourist areas or going into any hillside or wash that shows evidence of historical mining.
- 3
Check boundaries and closures
Confirm you're on BLM land, not Kofa National Wildlife Refuge (south of I-10 along US-95) or Arizona State Trust land. Check BLM Arizona for fire restrictions and post-monsoon road damage.
- 4
Prepare for desert conditions
Even in winter, the desert can be cold at night and hot by midday. Carry at least 1 gallon of water per person per day. Tell someone your planned location and return time. Carry basic recovery gear (traction boards, tow strap) if driving any unpaved BLM roads.
- 5
Collect within the 25 lb limit
Track your weight as you go — a digital luggage scale is useful. Keep all collection personal-use only. Fill any small test pits before leaving. Leave the area in as natural a condition as you found it.

Permits & Licenses
| Permit | Required? | Notes |
|---|---|---|
| Casual rockhounding permit | No | No permit required for personal-use casual collecting under 43 CFR § 8365.1-5(b)(2). BLM Arizona sets the personal-use amount at 25 lb/day and 250 lb/year. Any commercial collection — selling specimens, guiding paid groups — requires a BLM minerals permit. |
| La Posa LTVA camping permit | No | Covers camping in the ~11,400-acre La Posa Long Term Visitor Area, where BLM also lists rockhounding as an activity. BLM's page doesn't say whether in-season day visitors who don't camp need a permit; ask the Yuma Field Office, (928) 317-3200. |
Time & Seasonal Restrictions
- 25 lbs per day, 250 lbs per year personal-use limit (BLM Arizona) — collecting beyond it without a permit is a violation even with no commercial intent
- Commercial collection — any sale or trade of collected specimens — requires a BLM minerals permit; casual-use exemption does not apply
- Active mining claims: the Quartzsite area has extensive historical and active claim activity; verify MLRS (mlrs.blm.gov/s/research-map) for any specific area before collecting
- Hand tools only — picks, chisels, hand shovels; no motorized excavation, mechanical extraction, or blasting
- Pack out all trash including tailings piles you create; leave no pits unfilled if practicable
- Kofa National Wildlife Refuge: rock and mineral collecting only in the Crystal Hill Area — 10 specimens or 10 lb (whichever comes first) per 12 months, surface material only, no tools or metal detectors, no digging
- New Water Mountains Wilderness (east of town, south of I-10): collecting allowed in reasonable amounts, but only with non-motorized hand tools and minimal surface disturbance (BLM Rock Collection FAQ; 43 CFR 6302.20)
- Desert tortoises here are Sonoran desert tortoises, which aren't federally listed, but collecting them from the wild is illegal under Arizona Game & Fish rules; leave any you see alone
Equipment Notes
- Rock hammer and chisels for breaking host rock to expose mineral specimens
- Flat-head pry bar for opening fractures in quartz veins
- Hand trowel or folding shovel for surface soil removal in wash gravels
- Sieve or classifier screen (1/4" and 1/8" mesh) for sorting gem gravel in dry washes
- Kneeling pad — desert ground is rocky and hard on knees during close work
- Spray bottle for wetting specimens to reveal true color (critical for jasper identification)
- Sturdy specimen bags — zip-lock gallon and quart sizes for sorting by find type
- Field loupe (10x) for on-site identification of crystal habits and cleavage
- Sun protection essential — Quartzsite receives 300+ days of sun; temperatures exceed 110°F June–September
What People Find Here
- Placer gold in the Plomosa Mountains washes near Quartzsite (USGS Bulletin 620-C; Plomosa Placers district); fine gold rather than nuggets for most visitors
- Quartz and quartz crystals, which BLM Arizona lists for the Yuma Field Office area
- Chrysocolla, malachite and other copper minerals around old mine workings in the Plomosa Mountains, not widespread surface float; stay off active claims and out of mine openings
- Petrified wood, which BLM Arizona lists as occurring within the Yuma Field Office; it counts toward the same 25 lb/day, 250 lb/yr limit
- Jasper, agate and chalcedony float, which visitors commonly report on the desert pavement; no primary source maps specific deposits
Penalties for Violations
← Scroll to see all columns
| Violation | Statute | Penalty |
|---|---|---|
| Exceeding casual-use quantity limits or commercial collection without permit | 43 CFR Part 8360; 43 U.S.C. § 1733 | Fine up to $1,000 and/or up to 12 months imprisonment; equipment and collected materials subject to seizure |
| Collecting on an active mining claim without claim holder permission | 30 U.S.C. § 26 (locator's exclusive right of possession of the claim surface) | Civil liability to the claim holder for minerals taken; state trespass or theft charges possible. BLM advises that collecting is generally not allowed on active claims |
Etiquette & Leave No Trace
- Fill any excavations you make — even small test pits in wash gravels; leave the surface as close to natural as possible
- Do not remove large anchor boulders or landmark rocks — other collectors use these as navigation references
- Respect any claim markers (monuments, posts, notices) — if you see active claim signs, move to a different area
- Do not block wash access roads with vehicles; seasonal rains can turn washes into flash-flood channels without warning
- If you encounter desert tortoises, maintain at least 20 feet distance and do not handle them — they can void their bladder when picked up, causing fatal dehydration

Frequently Asked Questions
How much can I collect at Quartzsite BLM?
BLM Arizona allows up to 25 lbs per day of rocks and minerals for personal, non-commercial use, with an annual limit of 250 lbs per person. These limits apply across BLM land in Arizona, not just Quartzsite. The federal rule itself (43 CFR § 8365.1-5(b)(2)) says only "reasonable amounts", so other states' BLM offices use different figures. Exceeding these amounts, or collecting for any commercial purpose, requires a BLM minerals permit.
Do I need to check for mining claims before collecting?
Yes, and this is important at Quartzsite specifically. The area has an exceptionally dense history of staked mining claims, many of which are still active or patented. Collecting on a valid mining claim without the claim holder's permission is a federal violation regardless of whether the claim is physically posted. Check BLM's MLRS Research Map (mlrs.blm.gov/s/research-map) for any specific area you intend to collect in. The Yuma Field Office at (928) 317-3200 can also advise on claim status for specific areas.
Can I collect at Crystal Hill near Quartzsite?
Yes, but under refuge rules, not BLM's. Crystal Hill is the only part of Kofa National Wildlife Refuge open to rock collecting: 10 specimens or 10 pounds per 12 months, whichever comes first, only material you can pick up without tools, and no digging or metal detectors.
Is the La Posa LTVA area open to day visitors without paying?
The LTVA permit is a camping permit: $180 for the season (Sept 15–Apr 15) or $40 for any 14 consecutive days. BLM's page doesn't state whether in-season day visitors who don't camp need one, so if you're only collecting for the day, confirm with the Yuma Field Office at (928) 317-3200. Off-season (Apr 16–Sept 14), day use is $10 per vehicle.
What minerals are found at Quartzsite?
Documented occurrences include placer gold in the Plomosa Mountains washes, quartz crystals and petrified wood (both listed by BLM Arizona for the Yuma Field Office), and copper minerals like chrysocolla around old Plomosa mine workings. Jasper, agate and chalcedony float are commonly reported on the desert pavement, but no primary source maps specific deposits.
Can I bring a metal detector along with rockhounding equipment?
Yes. Metal detecting for personal use on BLM open land is also permitted under casual-use rules. However, the metal detecting rules and the rockhounding rules are separate: 25 lbs/day covers rocks and minerals, not metallic objects. Any archaeological artifact or item over 100 years old is protected under ARPA (Archaeological Resources Protection Act) — do not remove it, and report significant finds to the Yuma Field Office.
