Prohibited

Lake McDonald, Glacier National Park

Montana, Flathead·Rockhounding

No: taking the colored rocks from Lake McDonald is prohibited. Glacier National Park bans removing any rock or mineral (36 CFR 2.1), and its compendium allows only berries. Look, photograph, and leave them.

National Park Service rules prohibit "possessing, destroying, injuring, defacing, removing, digging, or disturbing from its natural state" any mineral resource in a park (36 CFR 2.1(a)(1)(iv)); the Lake McDonald pebbles are covered
Glacier's 2026 Superintendent's Compendium allows visitors to gather only edible fruits, nuts and berries (one quart per person per day); it designates no rocks, minerals or other natural objects

Laws That Apply to These Sites

36 CFR § 2.1 Explained: Why National Park Land Bans Collecting

One federal regulation is cited more than any other statute on this site — across metal detecting, beachcombing, fossil hunting, and rockhounding alike. It actually contains two separate bans, not one, and knowing the difference is the reason a metal detector broken down in a backpack is legal to carry across the same ground where using it would be a federal offense.
