Aspen Acres Fire Grows to 50,000 Acres, Forces Evacuations

A wildfire burning near the Aspen Acres campground in southern Colorado has become the state's largest active blaze, scorching more than 50,000 acres and forcing mandatory evacuations across two counties.

Explosive Growth Fueled by Record-Dry Conditions

The fire ignited on Monday, June 29, near the Aspen Acres campground in southern Colorado. Fire officials believe it was human-caused, though the exact circumstances remain under investigation.

By July 2, the fire had burned roughly 50,187 acres — more than 78 square miles — across Pueblo and Custer counties, with containment still at zero. Extreme fire behavior has been driven by record-low fuel moisture, excessively dry timber, humidity dropping as low as 3 to 5 percent, and sustained winds near 30 mph. Earlier in the week, erratic gusts reached up to 100 mph, conditions that fire officials say made the blaze especially difficult to predict or contain.

More Than 180 Structures Lost as Mountain Towns Empty Out

At least 180 structures have been destroyed so far, an estimated 125 in Pueblo County and 55 in Custer County. Officials expect the count to climb as damage assessment teams gain safer access to the burn scar. One firefighter has been injured; no civilian injuries or deaths tied to the fire have been reported.

Mandatory Level 3 "Go" evacuation orders remain active across both counties, with Beulah, Rye, San Isabel, Lazy Acres, and Wetmore among the communities hit hardest. An evacuation center has opened at Pueblo County Parks and Recreation on Cooper Place, while residents evacuating with large animals and livestock are being directed to the Colorado State Fairgrounds.

Alaska Incident Team and California Engines Join the Fight

More than 300 firefighters are currently working the fire, with command transitioning to a complex incident management team arriving from Alaska. Roughly 100 additional fire engines are en route from California to reinforce ground crews. Governor Jared Polis said 14 large air tankers are dropping water and retardant when wind conditions allow safe flying.

FEMA has authorized federal funds to cover 75 percent of Colorado's eligible firefighting costs, citing the scale of the disaster, and Polis has issued a state disaster declaration to unlock additional resources.

Smoke Pushes Air Quality Alerts Into the Front Range

Dense smoke from the fire has triggered air quality alerts stretching north through Colorado Springs and Denver along the Front Range. Officials are urging older adults, young children, and people with respiratory conditions to stay indoors while smoke levels remain elevated.

With the fire still at zero percent containment and dry, windy conditions expected to persist, officials have not offered a timeline for when evacuation orders in Pueblo and Custer counties might be lifted.
