Official information

For this incident’s official status, evacuation orders, and emergency information, go to the responsible agencies — this page is a data record, not an emergency service. WFIGS does not publish a per-incident public link, so these are the official portals to search:

InciWeb — the national incident information system (search by name).
Colorado Division of Fire Prevention & Control — state lead for wildfire coordination in Colorado.
USDA Forest Service, Rocky Mountain Region — federal lead on national forest lands in Colorado.
National Interagency Fire Center (NIFC) — interagency coordination; publisher of the WFIGS system of record this map reads.
National Interagency Fire Center — publisher of the WFIGS system of record.

Where this comes from

Every field is the WFIGS incident record from the National Interagency Fire Center, shown with its agency “valid as of” time. Missing fields are shown as missing, never zero or inferred. A perimeter is drawn only when the agency published one; nearby heat detections are NASA FIRMS, which are not confirmed fire. See the data sources & methodology page.
