Mammoth Fire Update – 6/12/21

Containment – 46%
Acres Burned – 709
Cause – Lightning

Yesterday’s Operational Shift

  • On the south perimeter where the fire burned into a lava flow, crews used water from hose lays to mop-up pockets of heat to further secure the fire line.
  • In steeper terrain on the fire’s western edge, crews used infrared technology to seek and mop-up remaining hot spots.
  • Near structures and interior roads, crews assessed and removed hazardous trees.
  • Fire crews built waterbars on fire lines in steeper terrain to prevent soil erosion.
  • Where fire line is contained, crews backhauled hose and water handling equipment.

Today’s Operational Expectations

  • Crews will continue to backhaul water handling equipment and begin fire suppression repair in areas of the fire where   containment has been achieved.
  • Firefighters will continue felling of dead or partially dead trees called snags that pose a hazard near structures and along roads.
  • Fire resources and equipment will be released from the Mammoth Fire to assist with other emerging large fires in the state of Utah.
