Why Oregon Sunstone Has a Lower Daily Limit Here
Oregon sunstone is a labradorite feldspar with copper platelet inclusions that produce aventurescence — a warm reddish-gold shimmer distinctive enough to make it Oregon's official state gemstone since 1987. It is one of the only copper-bearing gem feldspar deposits in the world.
At most BLM rockhounding sites, the casual-use limit is 25 lb per person per day under 43 CFR § 8365.1-5. The Spectrum Sunstone Public Collection Area operates under a lower limit — approximately 1 lb per day for sunstones — set by the BLM Lakeview Resource Area's management plan. The designation reflects the resource's commercial value and the sustained visitor pressure from both hobbyists and commercial collectors who operate the adjacent private fee-dig claims (Spectrum Mine, Dust Devil Mine, and others). The free public area and the private operations sit on different parcels with different rules — same mineral, completely different collecting framework.
BLM Public Area vs. Adjacent Private Fee-Dig Operations
| Feature | BLM Public Area | Private Fee-Dig Claims |
|---|---|---|
| Cost | Free | $100–$200/day approximate (varies by claim) |

Fee-dig pricing approximate based on general market rates as of 2026; contact individual claim operators for current rates and availability.
How to Stay Within the BLM Public Collecting Area
- 1
Download the BLM surface management map before you leave
Navigate to blm.gov or use the BLM's GeoCommunicator/LR2000 portal and download the Lake County, Oregon surface management layer. This shows the distinction between open BLM land and private unpatented mining claims in the Rabbit Hills area.
- 2
Call BLM Lakeview FO for current GPS waypoints
The BLM Lakeview Field Office at (541) 947-2177 can provide current GPS coordinates for the public collecting area boundary corners. Third-party coordinates for this site circulate online but are not always current; official coordinates are more reliable.
- 3
Identify claim corner stakes on the ground
Unpatented mining claims are marked with wooden posts or PVC pipes at their corner points. If you encounter clearly posted stakes, you are at or near the boundary of a private claim. Stop collecting and verify your GPS position.
- 4
Track your daily haul weight
The ~1 lb/day limit is self-enforced with no on-site staff. A small kitchen scale in the vehicle, or a rough estimate using a zip-lock bag as a reference, keeps you within the limit. Do not exceed it on the assumption you will not be encountered — federal land use violations apply regardless.
Oregon sunstones form in Miocene basaltic lava flows — roughly 15 to 40 million years old — that spread across southeastern Oregon's high desert plateau. The feldspar crystals grew slowly within cooling basalt columns, and over millions of years of weathering eroded free of the matrix. On the light-colored playa surface of the Rabbit Hills area, those freed crystals catch morning light and are visible to a trained eye before any digging is needed.
The copper content is what makes these stones valuable and geologically distinctive. Most labradorite feldspars worldwide contain iron-oxide inclusions that produce silver or gray schiller. Oregon's copper-bearing crystals produce warm red-gold tones instead. The highest-copper stones tend to remain deeper in the matrix — which is why the private fee-dig operations consistently pull gem-quality red material that the public area's surface collecting cannot reach. For most visitors, the free BLM area produces excellent pale-to-yellow stones and occasional orange specimens; deep-red material is a fee-dig proposition.
Best time to arrive and how to spot sunstones on the surface
The most productive surface collecting window is early morning after a rain event or sustained wind. Rain washes sediment from the playa surface; wind concentrates lighter material and leaves denser feldspar crystals exposed. Arrive before 9 AM when low-angle morning light catches the copper schiller at a shallow angle — stones invisible at midday flat-light become clearly reflective from 10 feet away in the early sun. Scan slowly across the pale playa surface; fresh sunstone faces are glassy against the dull gravel background and catch the light distinctively.
Permits & Licenses
| Permit | Required? | Notes |
|---|---|---|
| BLM casual collecting | No | No permit required for personal-use collecting within the daily limit at the designated public area. Self-regulated site with no entry fee. BLM Lakeview FO at (541) 947-2177 can confirm current rules and GPS boundaries before your visit. |
Time & Seasonal Restrictions
- Daily limit approximately 1 lb per person per day for sunstones — this designated area carries a lower limit than the standard BLM 25 lb/day casual-use rule; confirm with BLM Lakeview FO
- Hand tools only: no motorized excavation, no sluicing, no mechanical screening equipment
- Private mining claims are clearly posted with corner stakes; trespassing on private claims is criminal under ORS 164.245 (Criminal Trespass II)
- Do not remove, relocate, or damage claim corner stakes or surface management markers
- No commercial sale of material collected under the no-permit personal-use provision
Equipment Notes
- No mechanized tools — garden trowel, hand pick, probe, or small screwdriver are standard; the goal is surface collecting and shallow hand-digging
- 10x loupe recommended for identifying copper schiller (aventurescence) in the field — gem-quality sunstones show a warm reddish-gold shimmer in reflected light; testing in the field prevents carrying worthless feldspar home
- Polarized sunglasses: midday playa glare makes surface spotting very difficult; low-angle morning light is far more effective
- 4WD or high-clearance vehicle strongly recommended for the gravel/dirt roads from Plush — roads are impassable when wet
- Ample water supply — no services for 20+ miles in any direction; temperatures exceed 100°F from June through August
What People Find Here
- Clear to pale champagne Oregon sunstone: most common surface find in the public area; small to medium crystals weathered from the volcanic tuff matrix
- Yellow to orange Oregon sunstone: moderately common; copper inclusions beginning to produce visible color shift
- Red or 'watermelon' bicolor sunstone: rare in the public area surface zone; more frequently produced in adjacent private fee-dig claims where mechanical excavation accesses deeper copper-rich matrix
- Glassy colorless feldspar fragments: common; not all material with slight sheen is gem-quality — learning to distinguish is part of the experience
Penalties for Violations
← Scroll to see all columns
| Violation | Statute | Penalty |
|---|---|---|
| Collecting on private mining claims without permission | ORS 164.245 (Criminal Trespass II) | Class C misdemeanor; up to 30 days jail and/or $1,250 fine |
| Exceeding daily collection limit or using motorized equipment | 43 CFR § 8365.1-5 / BLM Lakeview FO resource management plan | Federal citation; material confiscated; potential suspension of collecting privileges |
Etiquette & Leave No Trace
- Backfill any holes you dig — the open playa is fragile; open pits impact the site visually and trap wildlife
- Do not disturb or remove private claim markers — corner stakes define the boundary between public BLM land and private claims; moving them is both illegal and dangerous for future visitors
- Collect only what you will actually use; the 1 lb/day limit is ample for display collections — do not attempt to maximize the limit for resale
- Pack out all trash; no facilities at the site and no staff to manage waste

Frequently Asked Questions
What is the daily collection limit at the BLM public sunstone area, and why is it lower than other BLM sites?
The designated BLM public collecting area operates under approximately 1 lb per person per day for sunstones — well below the standard BLM casual-use limit of 25 lb/day that applies at most rockhounding sites under 43 CFR § 8365.1-5. The reduced limit exists because the BLM Lakeview Resource Area management plan designates Oregon sunstone as a special-status resource in this area; the lower limit is intended to prevent depletion of surface-accessible material by high visitor volumes. Always confirm the current limit with BLM Lakeview FO at (541) 947-2177 before visiting, as management plan provisions can be updated.
How do I know where the BLM public area ends and private mining claims begin?
Private mining claims are marked with corner stakes — wooden posts or PVC pipes — at the claim boundaries. The BLM Lakeview FO can provide GPS coordinates for the public collecting area corners; call (541) 947-2177 or download the BLM Oregon/Washington surface management map (available at blm.gov) for Lake County. The split between BLM and mining claim land is visible as different parcel categories on the map.
What makes Oregon sunstone different from other gem feldspars?
Oregon sunstone is a labradorite feldspar containing microscopic copper platelet inclusions suspended within the crystal. These platelets produce aventurescence — a warm reddish-gold shimmer visible in reflected light, called 'schiller.' Most other sunstones worldwide contain iron-oxide inclusions (goethite or hematite) producing silver or gray shimmer; Oregon's copper-bearing variety is geologically unusual. Color ranges from colorless champagne to deep red, with rare bicolor 'watermelon' stones showing both green and red in the same crystal.
Can I use a shovel or digging tools at the BLM public collecting area?
Hand tools only — a garden trowel, hand pick, or probe is the standard kit. No motorized or mechanized equipment is permitted under BLM casual-use rules at this area. The adjacent private fee-dig operations allow heavy equipment, which is why they consistently access larger and more vivid material than surface collecting can reach.
Is there an entry fee for the BLM public collecting area?
No. The BLM area is free, requires no reservation, and has no on-site staff. The only cost is fuel — the site is approximately 55–60 miles from Lakeview, OR, on paved highway to Plush and then gravel/dirt road from there.
