Shamrock Fire – June 11, 2021 Evening Update

  Acres: 1,168 acres Start Date:  June 9, 2021 Cause: Under Investigation Containment: 0% Total personnel: 157 Location: 11 miles northeast of Nogales, AZ Fuels: Short grass and brush   Operations: Firefighters, Thursday night into Friday morning, were able to complete a crucial burnout operation on the eastern portions of the fire, which allowed the Southeast Zone Type 3 Incident Management Team to shift air resources to the western and northern portions of the fire. With this shift, the Operations Section Chief feels confident that ground and air resources were able to slow and even stop western forward progress of the fire.   Today, firefighters mopped up edges of the burnout that occurred Thursday night and performed direct attack on the northwest corner of the fire. Crews are challenged by continual dry conditions and high temperatures.   Not only do the extreme weather conditions hamper our suppression, but the steep rocky terrain is also a challenge to the firefighters. In addition to full suppression of the Shamrock Fire, the incident management team is also responsible for responding to any new fire starts in the area surrounding the fire.      The resources assigned include: 5 Crews, 6 engines, 3 Very Large Airtankers (VLAT), 3 Large Air Tankers (LAT), 3 Helicopters, 1 Air Attack, 1 Lead plane, and miscellaneous overhead.

Temporary Flight Restriction (TFR): A Temporary Flight Restriction (TFR) is in place over the Sycamore Canyon Fire. It is the responsibility of any pilot to reference this TFR before planning their flight.

Wildfires are a No Drone Zone. If you fly, we can’t.  Flying Unmanned Aircraft Systems (UAS), also known as drones, near wildfires could cause injury or death to firefighters as a result of an aircraft collision. The TFR also applies to the operation of drones. If an un-permitted drone is spotted over a fire, any aircraft working on the fire will be grounded until the drone has left the area or is accounted for. This hampers firefighters' ability to protect lives, property, and natural cultural resources and could result in fires growing larger. For more information visit: and
