In Mountain Home, Idaho, investigators have concluded that arcing power lines were the cause of a recent brush fire that devastated the area. The Idaho Department of Insurance reported that the fire destroyed 15 homes and at least 12 vehicles, including inventory from a local wrecking yard. Numerous outbuildings also suffered damage.

Investigation and Cause

The investigation, led by the Idaho State Fire Marshal’s Office, began shortly after the fire erupted on May 27. It was determined that the fire started when wind caused two electrical lines to touch, creating arcing and sparks. This resulted in molten aluminum and melted wire insulation falling into dry vegetation, igniting the blaze. The fire spread rapidly due to sustained winds of 30 to 35 mph, with gusts reaching up to 52 mph.

Prior to the fire, Idaho Power had responded to a report from a nearby homeowner about low-hanging service lines that posed an electrocution risk. The powerline had been lifted four days before the fire occurred.

Impact and Response

Six law enforcement personnel were hospitalized due to the fire, with five officers treated and released. One officer remains in the hospital, but officials have expressed relief at their recovery and the safety of others affected by the fire. The Elmore Sheriff Employees’ Association has established a fund to support the deputies and their families.

The Idaho State Fire Marshal’s Office commended the collaborative efforts of various agencies involved in the investigation. Fire Marshal Knute Sandahl stated, “Due to their collaborative efforts, we were able to quickly determine the cause.”

The Department of Insurance praised first responders for their efforts and encouraged communities to plan and mitigate potential fire events. This wildfire, while destructive, could have been far worse without the swift action of emergency personnel.
