Trails within 100 km
Ice Lake Basin — 81 km away, live AQI and conditions

Distance is not the whole question — smoke carries much further than fire, and trailheads and roads close well before flames reach them. Each trail page shows live AQI; check the managing agency and inciweb.nwcg.gov for closures before you drive.

What does “100% contained” mean here?

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.

Where do these numbers come from?

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.

Can I still hike near it?

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.
