Active Fire Perimeters
activeFirePerimetersMapped perimeter footprints of currently active wildfires from NIFC's WFIGS Current Perimeters feed. Each polygon is the latest reported perimeter for one incident, categorized as Wildfire Daily Fire Perimeter or Prescribed Fire. No attribute field marks the state; the layer is filtered to Wyoming via the same bbox spatial filter used elsewhere in the alternate viewer. Pairs with the Active Wildfires points layer incidents too small to have a mapped perimeter still appear there.
