Flames engulf homes as the Marshall Fire spreads through a neighborhood in the town of Superior in Boulder County, Colorado on December 30, 2021. - Hundreds of homes are feared lost in fast-moving wildfires in the US state of Colorado, officials said Thursday, as flames tear through areas desiccated by a historic drought. At least 1,600 acres have burned in Boulder County, much of it suburban, with warnings that deaths and injuries were likely as the blaze engulfes hotels and shopping centers. Extreme winds topping 100 mph caused grass fires to quickly spread into the Colorado towns of Superior and Louisville resulting in the mandatory evacuation of over 30,000 residents. Colorado Governor Jared Polis has declared a state of emergency due to the grass fires in Boulder County.
