Live wildfire perimeters for Utah this year, pulled straight from the national
WFIGS interagency perimeter service and refreshed automatically. Fires are shaded
by status: still active vs. contained, out, or older/inactive. Acreage is
computed in your browser from each perimeter's shape; where a fire has several
perimeters on file, only its largest is counted so
totals aren't double-counted.
Data Source:
• WFIGS Interagency Perimeters — Year to Date (NIFC / national fire GIS)
• Status from the incident's out / containment dates and perimeter recency; perimeters may lag the fire on the ground.
• Acreage computed from the perimeter geometry.
