Wildfire South of Colorado Springs Grows to 7,300 Acres With No Containment

Why It Matters

A rapidly expanding wildfire in Colorado south of Colorado Springs has burned over 7,300 acres and shows no signs of containment, threatening critical infrastructure and forcing prolonged highway closures. The 24 fire, which ignited on Wednesday, March 18, 2026, has prompted officials to maintain closures of Colorado Highway 115—a key connector between Colorado Springs and Penrose—through at least Friday, disrupting regional transportation and commerce.

The fire’s location on and near Fort Carson Army base adds complexity to firefighting efforts, as crews must coordinate across military and civilian jurisdictions. While no injuries have been reported, the rapid growth trajectory underscores Colorado’s vulnerability to spring wildfires as weather patterns shift and fire seasons extend.

What Happened

The 24 fire began Wednesday near mile marker 24 on Colorado Highway 115 and has expanded dramatically over five days. By Monday morning, March 23, 2026, the wildfire had consumed 7,385 acres—a significant jump from 4,900 acres reported just one day earlier on Sunday.

Despite the fire’s rapid growth, firefighting efforts achieved a critical milestone overnight Sunday into Monday. Officials reported that crews “successfully tied in all control lines, boxing in the fire,” meaning they established a perimeter containing the blaze’s spread. However, officials emphasized that “control lines remain strong” as of Monday morning, indicating the fire is not yet contained but is being held in place.

The fire originated off the highway, not directly on Fort Carson Army base property, though it is now burning on the east side of Colorado 115 on military land. This dual jurisdiction complicates response efforts, requiring coordination between civilian firefighting agencies and military resources.

By the Numbers

• 7,385 acres burned as of Monday morning, March 23, 2026
• 4,900 acres burned on Sunday—showing a 50% increase in just 24 hours
• 5-day duration from initial ignition on Wednesday, March 18 to Monday status update
• 0% containment as of Monday morning, though control lines established overnight
• 0 injuries reported despite the fire’s rapid expansion across thousands of acres

Highway Closures and Regional Impact

Colorado Highway 115 remains closed on the west side of Fort Carson and will likely stay closed through Friday, March 28, 2026. Officials stated the closure will be reevaluated daily, meaning it could extend beyond Friday depending on fire behavior and air quality conditions.

The highway closure disrupts the primary route between Colorado Springs and Penrose, forcing residents and commercial traffic to use alternative routes. This impacts supply chains, emergency services coordination, and daily commutes for residents in the affected region.

Zoom Out: Colorado’s Wildfire Crisis

The 24 fire is one of several significant wildfires affecting Colorado in recent years, reflecting a broader national trend of larger, more intense fires driven by drought, higher temperatures, and extended fire seasons. Colorado has experienced record-breaking fire seasons, with multiple incidents exceeding 10,000 acres in recent years.

Spring fires, once less common in Colorado, are becoming increasingly typical as snowmelt occurs earlier and temperatures warm faster. The 24 fire’s rapid growth in March demonstrates how vulnerable the state remains to early-season wildfires before summer heat peaks.

Fort Carson Army base has hosted several major fires in recent decades, making wildfire preparedness and evacuation coordination essential elements of the base’s emergency management protocols. The intersection of military operations and civilian firefighting resources requires continuous coordination and resource sharing agreements.

Investigation and Next Steps

The cause of the 24 fire remains under investigation by Colorado authorities. While the fire started off the highway, investigators will examine weather conditions, equipment use, and human activity to determine the ignition source.

Firefighting crews will continue monitoring control lines and working to achieve full containment in the coming days. As weather patterns shift and conditions change, officials will reassess highway closures daily, potentially reopening Colorado 115 as fire behavior stabilizes.

The Colorado Division of Fire Prevention and Control will provide daily updates on acreage, containment progress, and expected reopening timelines for critical infrastructure.
