The resultant fuels- driven fires are moving much quicker and more intensely than many firefighters have experienced. Firefighters may not have seen this type of fire behavior in well over a Fdecade. Past effective traditional tactics are less effective this season. The Preacher Fire was started by lightning at approximately 0330 0n July 24, 2017. Local fire department personnel arrived on scene soon after, with additional firefighting resources arriving throughout the day. By early afternoon, the crews and aviation assets had made significant progress and felt the fire was close to being buttoned up. However, at approximately 1700, a wind shift occurred and pushed the fire past containment lines at the heel of the fire. The fire rapidly grew from 400 acres to over 5,000 acres. As a result, the escape route for the Iron Mountain Type 2 IA hand crew lookout was compromised, forcing him to retreat from the fire through unburned fuels. During his escape, he dropped his line gear, inadvertently leaving behind his fire shelter. After retreating for approximately one mile, he started an escape fire to create a safety zone. This aided a Type I helicopter to quickly locate him. After a brief radio exchange between the lookout and the helicopter, the helicopter landed. The lookout boarded the aircraft and was flown to the helibase at the Minden-Tahoe Airport. He was then driven to the local hospital for evaluation and treatment, and sent to the nearest regional burn center. An interagency U.S. Forest Service and BLM Facilitated Learning Analysis (FLA) Team arrived on July 27. The team included diverse subject matter experts (SMEs) from four regions within the two agencies. The team was asked to focus on how the events and decision-making that led up to this incident, made sense to those involved. Methods. The FLA Team completed a 72-hour Report. The FLA Team conducted interviews, made site visits and gathered information to prepare a Rapid Lesson Shared (RLS) document that focused on fuels and fire behavior. The FLA Team completed this Facilitated Learning Analysis (FLA), which focused on the events and circumstances of July 24. The Team gathered and analyzed photos, videos, audio fragments, maps, dispatch logs, and incident documentation. They shared portions of the Narrative, Lessons Learned with key interviewees to clarify details and facilitated a group dialog session with the Iron Mountain Type 2 IA hand crew to generate deeper learning from this event. 2 Preacher Fire Facilitated Learning Analysis (FLA) Report Structure. The FLA Team developed the report structure based on the details of the incident, the needs of the organization, and FLA principles. This report includes these sections: Conditions Affecting the Preacher Fire. Describes fuel conditions, fire suppression tactics, weather, communication challenges and the area’s fire history. The Story. Describes events surrounding the entrapment and emergency extraction, and what the fuels and fire behavior conditions were leading up to the day of the fire. Lessons Learned, Observations, and Recommendations from Participants. Offers forward-looking perspectives from the involved personnel. Their thoughts are offered with minimal processing to provide material for future discussion and action. Discussion and Analysis. Takes a deeper look at events and circumstances shaping this event and provides opportunities for group discussion. Summary and Conclusions. Provides insights into new issues and helps reinforce existing safety practices and protocols. Recommendations. Provides concrete action points for programmatic improvement, from the FLA Team. Maps.

This area of Nevada has experienced several years of drought, followed by record-breaking snow in 2017, which produced twice as much moisture than normal. The excessive winter moisture promoted vigorous growth of cheatgrass, a non-native invasive species, and considerably changed the fuel matrix in the cheatgrass/sagebrush/pinyon-juniper communities from recent years. Normal fire return intervals in this area were 60-110 years; with cheatgrass, fire return intervals have decreased to five years or less. Cheatgrass is highly flammable, grows faster and displaces native plants such as sagebrush. The area where the Preacher Fire occurred has not burned since 2013, which resulted in a dense mat of cheatgrass underneath the new cheatgrass crop. Cheatgrass 3 Preacher Fire Facilitated Learning Analysis (FLA) The Great Basin Coordination Center issued a Fuels and Fire Behavior Advisory prior to the July 24 incident. It was updated on July 28, 2017 and most recently on August 11, 2017. Fire Suppression Tactics. Due to the density of this season’s cheatgrass crop, water and retardant drops were less effective than in previous years. Retardant drop levels were increased to improve retardant effectiveness. In addition, use of dozers as a fire fighting tool in this area were restricted due to sensitive resources and the mix of federal and private lands. Weather Conditions. On the morning of July 24, strong thunderstorms moved through the area, producing numerous lightning strikes but little moisture. A high pressure system then began to build over the area, bringing drier air and warmer temperatures. The topography of the Pine Nut Mountains, in conjunction with valley floor heating, regularly produces variable, gusty and erratic winds throughout the day. During the summer months along the Sierra Front Range, a meteorological condition known as Zephyr winds that blow from the west and southwest, commonly occur in the mid-afternoon until late evening. This condition is caused by a temperature differential between the Eastern
