None of the trails we track are within 100 km of this fire. Smoke still travels far beyond that, so check the AQI on whichever trail page you are headed for.
Containment is the share of the fire's perimeter that crews have a control line around — not how much of the fire is out. A 95% contained fire can still put up plenty of smoke; a 0% contained fire is still growing freely.
The NIFC/WFIGS Incident Locations feed — the official interagency record used by fire managers. We re-read it every 30 minutes and stamp the read time. The day-by-day table is our own record of those reads; acres sometimes drop when a perimeter is remapped, and we label that rather than smoothing it out.
Check the managing agency and inciweb.nwcg.gov for closures first — they close roads and trailheads well ahead of the fire. Then check the live AQI on the trail page itself; smoke is usually what decides the day, not flames.
