Black Mountain Fire in Colorado: Updates for Sept. 4, 2021 – Cause determined

GRAND COUNTY, Colorado (KDVR) – A fire that burned near the east was triggered by a lightning strike on August 29.

The cause of the Black Mountain Fire was discovered through the use of photos and videos of the fire along with mapping technology to locate the tree that was struck by the lightning that started the fire.

The fire covers 416 acres and is 21% contained, but was a threat in the Grand County area due to dry conditions and winds that are causing possible rapid spread.

According to a tweet from Medicine Bow-Routt National Forests and Thunder Basin National Grassland, “Along the path of a lightning-struck tree, sap is boiling, steam is generated, and cells explode in the wood, causing physical damage and, in many cases, inflammation of the fall Fire.”

The warmer and windier weather on Saturday is expected to increase fire activity. Air and ground crews of 180 men will continue to fight the fire with water droplets and pipe containment.
