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: Opalized wood turns up in gravel exposures and road cuts around Leesville, much of it on private land or within Fort Polk boundaries. Collect only from clearly public ground such as open Kisatchie National Forest tracts and public rights of way, and secure landowner permission anywhere else. Avoid all military reservation land.

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.
