Checks specific to this location
- Confirm parcel ownership and obtain required permission before entering or removing material.
- Check this protected area’s current removal and access restrictions; a recreation destination may be viewing-only.
- Treat this record as research or viewing context unless the current authority explicitly confirms the proposed collecting activity.
- Verify the exact destination, the land manager’s latest rules and safe travel conditions before leaving.
When was this information last checked?
The recorded review date is August 30, 2026. Treat that date as the evidence snapshot used for this classification. Conditions can change after review, so field decisions should use the newest posted rules and manager information.
Is a map pin the same as collecting permission?
No. A map pin answers a navigation or geographic-context question. The status and evidence answer the permission question. Exact coordinates, public destination addresses and approximate county or regional context are deliberately kept separate so geographic precision is not confused with legal authority.
