Colorado's Worst Wildfire Caused by Smoldering Fire and Power Lines.

Embers from a scrap wood fire and a sparking power line caused the 2021 Colorado wildfire that destroyed nearly 1,100 homes and left two people dead, according to authorities. The fire caused $2 billion in damage, making it the most destructive in Colorado history. The investigation took 18 months, but criminal charges were not warranted for either The Twelve Tribes that occupied the home or the utility in charge of the power line. Xcel Energy strongly objected to the findings of the investigation. Experts say similar events will become more common as climate change warms the planet and suburbs grow in fire-prone areas.
