Dual Causes Identified for Marshall Fire: Reignited Burn and Xcel Power Line Spark.

The 2021 Marshall fire in Boulder County was caused by embers buried for six days on a residential property reigniting and sparks from an "unmoored" Xcel Energy power line. The district attorney's office found "insufficient or no evidence of a crime" and no reason to file charges against Xcel Energy. A group of more than 20 victims of the fire filed a new lawsuit against Xcel, alleging negligence in its operation of its power lines and equipment. The fire destroyed over 1,000 homes and businesses, causing an estimated $2 billion in losses, and resulted in two deaths.
