Boulder County Wildfire History

Boulder County Wildfire History

Wildfires have always been a natural occurrence in Boulder County. Increased human development and recreation, land management practices – including fire suppression over the last 100 years – and factors such as steep terrain, drought, high temperatures, and strong winds have resulted in an environment prone to extreme wildfire behavior. The Black Tiger fire in 1989 was the first of many catastrophic wildfires in the county.
