Bureau of Land Management Rockhounding Regulations

The Bureau of Land Management (BLM) defines rockhounding as collecting reasonable amounts of mineral specimens, rocks, semi-precious gems, petrified wood, and invertebrate fossils.

Invertebrate fossils refer to the remains of creatures without bones, such as corals and shellfish, as well as common plant fossils.

Generally, public lands are open to rockhounding, except in areas like National Monuments. Always verify whether the land where you plan to collect rocks, minerals, or fossils is managed by the BLM, as jurisdictional boundaries may not be clearly marked.

In Oregon and Washington, BLM regulations allow a no-fee daily limit for personal-use collection of 25 pounds plus one piece. The yearly limit is 250 pounds, which includes minerals, semi-precious gemstones, common invertebrate fossils, petrified wood, and other rocks.

Only hand tools, such as shovels, picks, and hammers, are allowed for collection. Metal detectors may also be used. However, using motorized or mechanized equipment, heavy machinery, and explosives is strictly prohibited.

Groups of individuals cannot combine their yearly allowances to collect a single item that exceeds 250 pounds. For pieces larger than this limit, you must contact your local BLM office for approval.

Rockhounding is prohibited at developed recreational sites unless explicitly designated as rockhounding areas.

In Wilderness Areas, rockhounding is limited to surface collection only. It is also essential to respect laws that protect cultural and historical artifacts. Items such as Native American artifacts (e.g., arrowheads, pottery fragments, or burial remains) and vertebrate fossils (e.g., fish, mammals, or dinosaurs) cannot be collected.

Before visiting a site, check with the BLM for up-to-date regulations, specific locations, and any potential mining claims to ensure compliance.

U.S. National Forest Rock Rockhounding

The U.S. Forest Service permits recreational rockhounding on most National Forest lands.

The U.S. Forest Service limits specimen collection to 10 pounds. Some National Forest lands are closed to collecting due to wilderness designation. Contact the U.S. Forest Service for up-to-date information on specific areas.

Vertebrate fossils, such as animal, dinosaur, and fish bones, cannot be collected. Archaeological items, such as pottery fragments, arrowheads, and other artifacts, are also prohibited from being collected.

Oregon Coast Rockhounding Regulations

A particular part of the beach might be part of the Oregon State Park. In this case, follow the regulations For Oregon State Parks. However, there are some general rules for collecting materials on the Oregon Coast beaches.

You can remove no more than one gallon of agates and other non-living items such as shells, stones, and fossils per person per day, up to three gallons per person per calendar year.

Oregon State Parks Rockhounding Regulations

Oregon State Parks allow rockhounding of small amounts of rocks, minerals, and fossils for personal collection. However, digging or otherwise disturbing park property is strictly prohibited.

At some state park locations, larger collections may be allowed upon approval of the park manager. Collecting on the ocean shore is also allowed but with specific limits.

US Army Corps of Engineers Rock Collecting Regulations

Rock collecting is prohibited within U.S. Army Corps of Engineers property boundaries, encompassing all reservoirs.

According to Section 327.14 of Rules and Regulations Governing Public Use of U.S. Army Corps of Engineers Land, "Removal or any alteration of natural formations, mineral deposits, historical and archaeological features, paleontological resources is prohibited except when in accordance with written permission of the District Commander."

Generally, County Parks in Oregon prohibit rockhounding.

Here is one example of Marion County's regulations. According to a program coordinator of the county parks, mineral collecting falls under the provision 12.05.220 "Damaging park property which states D. Cut or remove any sand, wood, turf, grass, gravel, stone or timber in or from any park, or make any excavation by any tool, equipment, blasting or by any other means in any park".

Contact offices of the County Parks for up-to-date information.

In Oregon wilderness areas, rockhounding is generally permitted, but it is limited to surface collecting only. This means that you can gather rocks, minerals, and fossils that are already on the surface of the land.

Abandoned mines are extremely dangerous and must be avoided. Open shafts, deteriorated support structures, rotten timber, lack of oxygen, and various poisonous gases can result in injury or death.

Collecting material remains of prehistoric or historic human life or activities, such as arrowheads or pottery pieces, is prohibited. Vertebrate fossils (e.g., dinosaur bones, fish, and other animals with backbones) and shark teeth may not be collected.
