Mammoth Fire Update – 6/9/21

708 Acres (change due to more precise mapping) 

Yesterday’s Operational Shift 

  • Tuesday saw red flag conditions with gusty winds, low humidity, and severe ongoing drought 
  • Fire crews, engines, and dozers continued direct suppression tactics, securing fire line and mopping up along the fire perimeter to safeguard Mammoth Creek Village. The fire is now 14% contained. 
  • Helicopters dropped buckets of water on areas of concentrated heat near the edge of the fire where fuels are heavier.  

Today’s Operational Expectations 

  • Red flag conditions will continue through 10 p.m. Thursday with the most critical fire weather expected in the afternoons with potential wind gusts over 30mph. 
  • Today, fire crews will use water from hose lays and helicopter bucket drops to mop up from the fire perimeter inward to extinguish any pockets of heat. This will further secure the fire line and keep the fire within its existing footprint to protect Mammoth Creek and Tommy Creek subdivisions. 
  • The fire will likely continue its minimal, creeping behavior within the fire perimeter. As winds increase there is potential for isolated trees to torch in the interior of the fire. 
  • Community and firefighter safety are top priorities for both Team 5 and the National Forests. 

EvacuationsFire Restrictions & Closures

Fire Resources 

282 personnel, 6 crews, 24 engines, 2 water tenders, 1 dozer, 4 helicopters 


A cold, dry front with no moisture is expected to move through on Thursday.  Most of Southern Utah is experiencing Red Flag conditions, which will continue through 10 p.m. Thursday, June 10, bringing hot, dry, gusty weather which could increase fire activity. A Red Flag warning means that critical fire weather conditions are occurring now or are imminent as a combination of strong winds, low relative humidity, and warm temperatures could contribute to extreme fire behavior.
