Los Alamos fire chief Doug Tucker said earlier this week that he thought the Las Conchas Fire was started by a downed power line.
Tucker was right.
An interagency investigative team led by New Mexico State Forestry has determined that the Las Conchas Fire was caused by a fallen tree that caught fire after coming into contact with nearby power lines, according to New Mexico State Forester Tony Delfin.
Investigators from New Mexico State Forestry, the USDA Forest Service, New Mexico State Police and Sandoval County conducted the investigation and were on scene shortly after the fire started on Sunday, June 26. Since then, the fire has burned more than 121,248 acres.
