Checks specific to this location
- Confirm any current permit, fee, booking or operator requirements before travelling.

- Reconfirm openings, temporary closures and seasonal access with the land manager.
- Verify the exact destination, the land manager’s latest rules and safe travel conditions before leaving.

The recorded review date is September 9, 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.
