Two years after the deadly and disastrous fire that destroyed hundreds of homes near Boulder, Colorado, investigators blame arcing Xcel power lines.

Boulder County sheriff Curtis Johnson announced the conclusion of investigators saying embers buried for six days on a residential property reignited and together with sparks from an “unmoored” Xcel Energy power line started the 2021 Marshall fire in Boulder County.

The arcing power lines were the result of 100 mph winds that swept across the region near Denver and Boulder reported the Colorado Sun.
