Oregon's BLM land runs on BLM Oregon/Washington's own definition of a "reasonable" personal-use amount. Its 2024 Rock Collecting Guide describes a reasonable daily amount as one that fits in a car trunk or a partial pickup load and weighs under 250 pounds. A full pickup load, repeat trips or more than 250 pounds needs a permit. The often-quoted "25 pounds a day" is the separate petrified-wood limit (25 lb plus one piece a day, 250 lb a year), not the Oregon limit for agate, jasper or obsidian; see our BLM collecting guide. That office-wide standard is useful for planning, but two documented exceptions show why it's still worth checking the specific site: the public sunstone area adds its own rules (hand tools only, nothing collected for sale or trade), and another site that looks like open BLM ground on rockhounding lists turns out not to be public land at all.

Sites documented so far — verdict and what makes each one different

SiteVerdictWhat's different about it
Succor Creek State Natural AreaAllowedState natural area plus adjacent BLM Vale District land; BLM Oregon/Washington's reasonable-amount standard applies on the BLM portion
Glass Buttes (BLM Prineville District)AllowedBLM's reasonable-amount standard applies, but the ground is a 10,000-year Native American obsidian quarry — worked (knapped) pieces are ARPA-protected archaeological material, not collectable regardless of size
Hampton Butte (BLM Prineville FO)AllowedBLM's reasonable-amount standard; picture and dendritic jasper
Spectrum Sunstone (BLM Lakeview FO)AllowedA BLM area set aside for public sunstone collecting. Hand tools only and no collecting for sale or trade. BLM publishes no sunstone-specific weight limit, so the reasonable-amount standard applies; confirm with the Lakeview District Office
Opal Butte (BLM-listed on many rockhounding sites)ProhibitedThe named gem-opal deposit is private, patented mining claim ground worked commercially since 1987 — not BLM land, despite being widely mislabeled as such
Saddle Butte Lava FieldUnclearAn 81,380-acre BLM Wilderness Study Area whose only documented protected value is a lava-tube cave system; no confirmed mineral deposit and no ACEC-specific collecting rule found published

Reflects verdicts already published on this site as of this writing. Always confirm current land status and any site-specific limit before a trip — BLM Oregon/Washington's reasonable-amount standard is the default; a site-specific rule overrides it.

"It's on a rockhounding list" is not the same as "it's BLM land"

Opal Butte is the clearest documented example: it appears on general rockhounding references as a BLM site, but the actual gem-opal deposit is a privately held, patented claim that has been commercially worked since 1987. The surrounding BLM Prineville District land follows the standard personal-use rules, but produces no comparable opal — confirming public land status for the specific deposit you're after, not just the general area, is worth the extra step.

Site Guides

Allowed

Glass Buttes (BLM)

Oregon, Lake·Rockhounding

Glass Buttes is open BLM land in the Oregon high desert where four varieties of obsidian — including rare fire obsidian — lie on the surface for personal-use collecting. BLM Oregon/Washington allows a reasonable amount with no permit, meaning under 250 lb a day. The catch most visitors don't expect: the site was a major Native American quarry for 10,000 years, and worked obsidian pieces are protected under ARPA regardless of how natural they look.

  • Surface collection of raw obsidian is allowed in reasonable amounts for personal use (43 CFR 8365.1-5(b)(2)). BLM Oregon/Washington's 2024 Rock Collecting Guide defines a reasonable daily amount as one that fits in a car trunk or partial pickup load and weighs under 250 lbs
  • ARPA (16 U.S.C. § 470aa) prohibits collecting any worked obsidian — projectile points, scrapers, or any piece showing human modification. Glass Buttes was quarried for ~10,000 years and worked material is mixed into the surface scatter
Allowed

Hampton Butte (BLM)

Oregon, Deschutes·Rockhounding

Hampton Butte is an open BLM site in Deschutes County where surface collection of picture jasper — including dendritic and landscape-pattern varieties — is allowed in reasonable personal-use amounts with no permit. Most visitors driving US-20 stop at Glass Buttes for obsidian; those who continue past Hampton find different material entirely.

  • Surface collection of rocks, minerals, and jasper is allowed in reasonable amounts for personal use (43 CFR 8365.1-5(b)(2)). BLM Oregon/Washington's 2024 Rock Collecting Guide defines a reasonable daily amount as one that fits in a car trunk or partial pickup load and weighs under 250 lbs
  • No permit required for personal non-commercial use; commercial collection requires a mineral materials permit from BLM Prineville Field Office
Prohibited

Opal Butte

Oregon, Morrow·Rockhounding

The gem-opal deposit at Opal Butte sits on private, patented mining claims — not BLM land. Surrounding public ground is open to standard Oregon BLM collecting but produces no comparable opal.

  • The commercial gem-opal deposit at Opal Butte sits on privately held, patented mining claims worked by West Coast Gemstones since 1987 — it is not BLM land and is not open to public collecting, despite frequently appearing on rockhounding lists as a BLM site
  • General BLM land surrounding the butte, managed by the Prineville District, is open to standard Oregon/Washington BLM collecting rules — a reasonable daily amount (up to 250 lbs, a partial pickup-truck load, for non-commercial use) with no fee or permit — but this ground does not produce comparable gem-quality opal

Saddle Butte Lava Tubes (WSA)

Oregon, Malheur·Rockhounding

Saddle Butte is a Wilderness Study Area, not the open BLM collecting ground the general rockhounding lists suggest — its 81,380 acres are protected specifically for an extensive lava tube cave system, and no confirmed gem-quality mineral deposit at this exact site turned up in official BLM sources.

  • Saddle Butte is a designated Wilderness Study Area (WSA) — 81,380 acres of BLM land in Malheur County, not a general-access rockhounding destination — overlaid by the Saddle Butte Lava Tubes Area of Critical Environmental Concern (ACEC), which protects the lava tube cave system as its specifically identified relevant and important value
  • BLM's general interim management policy for WSAs allows non-motorized, hand-tool casual use that causes no more than minor surface disturbance, which would typically cover surface rockhounding — but no ACEC-specific stipulation addressing rock or mineral collecting near or within the lava tubes was found published online
Allowed

Spectrum Sunstone Public Collection Area (BLM)

Oregon, Lake·Rockhounding

Sunstone collecting is free at the BLM Oregon Sunstone Public Collection Area near Plush. BLM allows a reasonable amount for personal use, hand tools only, and no collecting for sale or trade. BLM publishes no sunstone-specific weight limit. Private mining claims surround the area and sit inside it, so know where you are.

  • BLM designated public collecting area; no entry fee and no permit required
  • Amount: a reasonable amount for personal use (43 CFR 8365.1-5(b)(2)). BLM publishes no sunstone-specific weight limit for this area. Its Oregon/Washington Rock Collecting Guide defines a reasonable daily amount as one that fits in a car trunk or partial pickup load and weighs under 250 lbs. Confirm with the BLM Lakeview District Office at (541) 947-6100 before visiting
Allowed

Succor Creek State Natural Area

Oregon, Malheur·Rockhounding

Succor Creek State Natural Area in eastern Oregon's Owyhee canyon country allows rockhounding within the state natural area without a permit for personal-use collection. The creek canyon cuts through Miocene rhyolite exposures that produce thunder eggs, jasper, and occasional obsidian nodules. Adjacent BLM land — the primary destination for serious thunder egg collectors — is open for free personal-use collection under standard BLM rules.

  • Personal-use rockhounding is allowed within the Oregon State Natural Area under Oregon Parks and Recreation Department rules — collection for personal non-commercial use without a permit
  • The adjacent BLM land (much of the broader Succor Creek area) follows BLM Oregon/Washington's personal-use rule: a reasonable amount, with no permit, defined in its 2024 Rock Collecting Guide as fitting in a car trunk or partial pickup load and weighing under 250 pounds (43 CFR 8365.1-5(b)(2))

Laws That Apply to These Sites

BLM Personal-Use Collecting Rules: Rocks, Minerals, and Fossils

Most BLM land allows collecting rocks, minerals and common invertebrate fossils for personal use, with no permit. Federal law sets no weight limit for rocks: just 'reasonable amounts'. The 25-pound figure is the federal limit for fossils and petrified wood, and some BLM state offices apply it to rocks too. Vertebrate fossils need a permit.
