Dude Fire (Arizona) – June 26, 1990

Today’s topic is dedicated to all wildland firefighters.
May we never stop learning.

June of 1990 will long be remembered as one of the hottest months in Arizona history. On June 26, record temperatures were reported at 122 ºF in Phoenix and 106 ºF in Payson. In addition to the extreme temperatures, Arizona had been in a severe three-year drought. This combination produced a critically high fire danger throughout the state, especially in the Mogollon Rim country on the Payson Ranger District of the Tonto National Forest (TNF) north of Payson. Fuels in the area are primarily ponderosa pine with an understory of mixed oak, manzanita, needle, and leaf litter, and scattered large (greater than 6-inch diameter) dead logs. Much of the understory brush was heavily draped with very dry pine needles. Live fuel moisture in the manzanita and oak was very low (76%). Fine dead fuel moisture was 3% and 8% for larger dead fuels.

At 12:30 p.m. on June 25, a dry lightning storm started a fire under the Mogollon Rim. The fire was on a steep, southwest-facing slope at 6,400 feet elevation. The fire was estimated from the air at 5 acres at 1:30 p.m., at 50 acres one hour later, and at over 100 acres by 4:15 p.m., with a spot fire one mile east of the main fire. By 6:00 p.m., a Type 2 Incident Management Team (IMT) had arrived and a Type 1 IMT and 18 crews had been ordered. Brisk down canyon winds pushed the fire, and it was 1,900 acres by 5:00 a.m. on June 26, threatening the forest subdivision of Bonita Creek Estates. A convection column, aided by combustion, began forming over the fire by 10:00 a.m. The column continued to grow and became a fully mature thunderstorm by 2:00 p.m. Radio and frequency issues caused a breakdown in communication between the crews and the IMT. The team transition mid-shift resulted in confusion between the crews and supervision. The thunderstorm also began to decay, creating strong downbursts channeled by the topography. This caused dramatic down- and cross-slope fire spread on nearly all sides of the fire. Members of the Perryville Fire Crew would not be able to escape from the fast and erratic fire spread. Five were injured. Six died on the fireline.

Discussion Points:

  • What was learned from the Dude Fire? Are those lessons still being shared to grow our safety awareness? Are you mentoring others who can learn from your experiences?
  • Do we have practices/policies in place now that are designed to prevent this type of tragedy? Risk Assessments, Incident Strategic Alignment Process, Strategic Risk Assessment, training, policy?
  • Do we have the same hazards in the fire environment, or have they changed? Discuss issues like recent radio recall or, dependence on technology.

6 Minutes for Safety Subcommittee

As we approach the 2025 Week of Remembrance (WOR), June 30–July 6, we dedicate this time to reflect on the past incidents from 2015 and honor the fallen through learning. Since its inception in 2014, WOR has honored wildland firefighters who made the ultimate sacrifice while encouraging critical discussions that reinforce lessons learned.

Throughout the week, we encourage thoughtful and generative conversations—whether in briefing rooms or at tailgates—that promote a culture of continuous learning and safety.

ETC Equipment Bulletin: 25-003 Flame-Resistant Shirt Survey

Date: June 12, 2025
Questions?  Please contact:
Equipment Technology Committee

The U.S. Forest Service National Technology and Development Program (NTDP) is seeking input on the Forest Service-designed flame-resistant (FR) shirt, currently available through the National Interagency Support Cache system and FedMall.

NTDP is conducting a product review to improve future FR shirt designs. As part of this effort, a short survey is now open for federal employees who have worn any of three recent FR shirt models. Feedback will guide design improvements to better meet the needs of wildland firefighters.

To comply with the Paperwork Reduction Act, responses are limited to federal employees. The survey is open through September 12, 2025.

The S-130, Firefighter Training (Blended), equips new wildland firefighters with essential skills through a mix of online learning and hands-on training. The course features a required online component and an instructor-led exercise, reinforcing online concepts with practical performance-based training.

The course builds competencies in wildland fire operations, safety, and equipment use, applicable across various operational environments. Both the online component and instructor-led field exercise must be completed to receive a certificate of completion. Students are required to finish the prerequisite S-190, Introduction to Wildland Fire Behavior, before enrolling in S-130, Firefighter Training (Blended).

EMC Memo 25-001: Interim Rapid Extraction Module (REMS) Training and Qualification Requirements

Date: June 3, 2025
Questions?  Please contact:
Emergency Medical Committee

The Emergency Medical Committee has issued interim guidance for Rapid Extraction Module Support (REMS) teams. Until further notice, Type I and II REMS teams must designate a team leader qualified at Firefighter Type 1 Squad Boss (FFT1) or higher. This temporary change replaces the Single Resource Boss (SRB) requirement, which is currently not feasible due to administrative barriers.

This memorandum does not include any other changes to the NWCG Standards for Rapid Extraction Module Support, PMS 552. This interim change takes effect immediately and will remain in place until further notice.
