On December 30, 2021 the devastating Marshall Fire roared through Superior and portions of Louisville, Colorado. The fire started south of Boulder, Colorado, and was fanned by intense winds along the Front Range Foothills.

Wind gusts from 70 to 100 mph occurred right at the base of the foothills, including Boulder and along Highway 93 south toward Golden.  The strong winds fanned a grass fire which originated near the small town of Marshall, and quickly spread east to Superior and Louisville.  At last count, 1,084 homes and seven commercial structures were destroyed, and 149 homes and another 30 commercial structures were damaged by the Marshall Fire.
