Rockhounding in California: federal desert, closed parks and a 15 pound exception
Updated
On this page7
Most legal rockhounding in California happens on federal land: national forest in the mountains and Bureau of Land Management (BLM) land in the deserts, where hobby collecting of reasonable amounts is allowed. California's state parks are the opposite. Their rule starts from "No person shall destroy, disturb, mutilate, or remove" rocks and minerals, and opens only units posted for rockhounding, with a limit of 15 pounds per person per day and no tools but a gold pan. This page sets out who manages which ground, the state park rule word by word, the BLM collecting areas the agency names, and who to ask.
Who manages California's ground
Federal agencies manage 45.3 percent of California, about 45.4 million acres (Congressional Research Service, data as of September 30, 2024) [1].
| Manager | Acres | Collecting, in one line |
|---|---|---|
| Forest Service | 20,838,146 | Small personal amounts, hand tools (national forests) |
| BLM | 14,989,808 | Reasonable amounts, noncommercial (BLM land) |
| National Park Service | 7,655,258 | Essentially closed (parks and monuments) |
| Defense | 1,597,180 | Closed unless the installation allows access |
| Fish and Wildlife Service | 311,107 | Refuge rules (refuges and military land) |
The large National Park Service share matters in the desert, where park boundaries meet BLM land with no change in the rocks. A geode you may keep on one side of a line is a violation on the other.
BLM desert land and the named collecting areas
On BLM land the regulation allows you to collect "reasonable amounts" of "rocks, mineral specimens, and semiprecious gemstones" for noncommercial purposes, except on developed recreation sites or where collecting is "otherwise prohibited and posted," and without "explosive, motorized or mechanical devices, except metal detectors" [2]. Collecting for "sale or barter to commercial dealers" needs a contract or permit [2]. There is no pound limit in the rule.
BLM's national rockhounding page links three California sites set aside for collectors [3]:
- Wiley Well District geode beds
- Chambless Rock Collecting Area
- Savahia Peak Rock Collecting Area
These are the safest first trips in the California desert, because BLM has already settled that collecting is allowed there. Each has its own BLM page with access notes and any local rules; read it the week you go, since road and fire closures change. Outside designated areas, check for wilderness boundaries, closures and mining claims before you collect; see mining claims.
The state park rule, as written
California State Parks regulations are in Title 14 of the California Code of Regulations. Two sections govern rocks.
14 CCR 4307, Geological Features. Subsection (a) prohibits anyone from destroying, disturbing, mutilating or removing earth, sand, gravel, oil, minerals, rocks, paleontological features or features of caves. Subsection (b) reads in full: "Rockhounding may be permitted as defined in Section 4301(v)." [4] The text on Justia is current through Register 2025, No. 26 (June 27, 2025) [4].
14 CCR 4611, Rockhounding. This section sets the terms where a unit is opened [5]:
| Point | What 4611 says |
|---|---|
| Where | Units or portions of units "(o)pen for Rockhounding will be posted"; in state recreation areas, collecting is limited to certain beaches and to stream gravel bars subject to annual flooding |
| How much | "One person may gather, in one day in one unit, not more than 15 pounds of mineralogical material"; the rule also allows "not more than one specimen plus 15 pounds" |
| Tools | "Tools, except goldpans to be used in gold panning, may not be used in rockhounding within a unit" |
| Sale | "Rocks or mineral specimens gathered within a unit may not be sold or used commercially for the production of profit" |
| Artifacts | Rockhounding "does not include the gathering of Indian arrowheads" or other archeological specimens |
| Gold panning | Muddy water must not be visible more than 20 feet from the operation |
Three practical readings follow. First, the default in a state park is closed; look for the posting, not for the absence of a "no collecting" sign. Second, 15 pounds is per unit per day, gathered by hand, and none of it may be sold. Third, arrowheads are never part of rockhounding; artifact law is on arrowheads and other artifacts.
A district order narrows it further
District superintendents issue orders for particular parks. Sierra District Order 683-22-009, signed May 5, 2022, covers South Yuba River State Park and Plumas-Eureka State Park. It states: "Rockhounding, except for recreational gold panning, is prohibited" in both parks [6]. Panning is confined to the beaches and gravel bars of the South Yuba River and Jamison Creek that flood annually, only gold pans may be used, and moving, carrying away or damaging rocks is prohibited [6]. Expect similar orders elsewhere and ask the park before you plan on 4611's 15 pounds.
Beaches
Beaches run by California State Parks fall under the same Title 14 rules, so 4307 and 4611 apply to agates and pebbles there too: no collecting unless the beach is posted open. Beaches managed by cities, counties or other agencies set their own rules; those were not confirmed for this page.
State Lands Commission land, tribal land and private ground
Riverbeds, tidelands and other state-owned land outside the park system may be managed by the California State Lands Commission. Its rules on rock collecting were not confirmed for this page; ask the Commission before you collect on a riverbed or tideland that is not inside a park or a BLM parcel.
Reservation land is governed by each tribe, and none of the sources here grants collecting rights on it. Private land needs the owner's permission, ideally in writing, as described on collecting on private land.
Telling the managers apart on the ground
Because a park, a wilderness area and an open BLM parcel can share one valley, find out who manages the exact spot before you pick anything up. Use the BLM surface management maps and the park's own boundary map, and follow the steps on finding out who manages a parcel. If you want to compare California's park rule with other states', the fifty-state reference lines them up.
Confirm with the California offices
Last verified October 2026. Before a trip, confirm with:
- BLM California, through the field office for the area and each site's page linked from BLM's Rockhounding page (Wiley Well, Chambless, Savahia Peak) [3].
- California Department of Parks and Recreation, the individual park: ask whether the unit is posted open under 14 CCR 4611 and whether a district order applies [4][5][6].
- California State Lands Commission, for state-owned riverbeds and tidelands (rule not confirmed here).
