Figure 2. Wildland fire activity in Arizona the morning of June 29. Yarnell Hill Fire Serious Accident Investigation 10
Part One: Factual & Management Report Narrative The purpose of this narrative is to help readers understand the events occurring around the Granite Mountain IHC on the day of the accident. It is impossible to construct a complete account of the crew’s movement and entrapment because they cannot give their perspectives. Instead, the Team relied on others involved with the fire and with the crew, as well as on data gathered during the investigation, to reconstruct the most accurate account possible. Different individuals can perceive the same event differently. This account acknowledges interpretations may vary from one person to the next, and there can be apparent inconsistencies between individual perspectives. However, in most cases, the Team corroborated key details with two or more data sources. Team members also shared portions of the narrative with key interviewees to correct and clarify important details. The narrative is in present tense to help readers place themselves in the boots of the people involved. Instead of personal names, the Team uses Incident Command System (ICS) or other acronyms to protect the privacy of personnel involved in the incident (see Appendix F for fire terminology and acronyms). Parts of the narrative occasionally backtrack to capture a variety of perspectives and simultaneous events on different areas of the fire. Friday, 28 June 2013 Several parties notify the Arizona Dispatch Center (Dispatch) of a lightning-ignited fire on State of Arizona land west of Yarnell at about 1730 on June 28. It is one of four fires on state lands in the vicinity caused by significant lightning activity. Dispatch begins documenting the incident at 1736 as the Yarnell Hill Fire. An Arizona State Forestry Division (AZSF) firefighter, a qualified Type 3 Incident Commander (ICT3) who has worked in the local area since 1995, coordinates responses to the lightning strikes. He and the BLM Duty Officer on scene anticipate multiple new lightning-caused fires in the morning. The AZSF firefighter asks Air Attack to fly the general area around Yarnell to confirm there are no additional fires. The Air Attack assigned to the Doce Fire flies over Yarnell Hill and initially has difficulty finding the fire due to lack of smoke. Once he spots it, he reports the fire is in a boulder field, has no vehicular access, and shows very little smoke. He spots no additional fires. They schedule another reconnaissance flight for the following morning. At 1940, the AZSF firefighter becomes the Type 4 Incident Commander (ICT4) for the Yarnell Hill Fire. On initial assessment, ICT4 notes the fire is less than a half-acre in size, 80 percent Yarnell Hill Fire Serious Accident Investigation 11
