Where to go rockhounding, state by state
Hobby rock collecting is generally allowed on Bureau of Land Management and U.S. Forest Service land, banned in national parks and wildlife refuges, needs permission on private and tribal land, and varies on state land, where most state parks ban it. Each state page shows how much of the state is open ground, which mineral sites the U.S. Geological Survey has recorded on it, and how much is under active mining claims.
