Where does this data come from?
The NIFC/WFIGS Incident Locations feed — the official interagency record. We refetch it
every 30 minutes and stamp the read time. Nothing here is estimated; when the feed is
silent, the page says so rather than showing an old number.
What does “percent contained” mean?
The share of the fire's perimeter crews have a control line around — not how much of it
is out. A 95% contained fire can still make plenty of smoke; a 0% contained fire is still
growing freely.
Is it safe to hike near one of these?
Distance is only half the question — smoke travels much further than fire, and roads and
trailheads close well before flames reach them. Check the trail's page here for live AQI,
then check the managing agency and inciweb.nwcg.gov for closures.
