Land & collecting status

Generally open to casual rockhounding

Most public-tagged spots sit on BLM, U.S. Forest Service, or other federal land where reasonable hand collecting of common rocks and minerals is allowed. Confirm posted rules and active mining claims before you dig.

Access note: The coral and quartz occur as float in fields and creek gravels on ground that is largely private farmland, so secure the landowner's permission before collecting off the road. Surface-collect from public creek gravels below the high-water mark where reachable from public access, and do not dig into banks or pastures.

Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.
