Thick smoke was seen rising over Aurora, Colorado, and was visible from Denver International Airport on Wednesday.
Photos and videos posted by witnesses on social media showed large plumes of smoke.
Planned prescribed burn
Initial reports suggested the activity could be linked to a planned prescribed burn at the Rocky Mountain Arsenal National Wildlife Refuge.
Controlled burning operations were scheduled for the day near East 56th Avenue and Memphis Street.
Officials said smoke could be visible for several miles across the region, while the refuge’s Wildlife Drive and trails remained open.
Aurora Fire Rescue wrote on X, "The large plume of smoke that can be seen on the north side of the city is from the Rocky Mountain Arsenal’s prescribed burn."
Storm Chaser Sam Sagnella wrote, “Despite this being a prescribed burn, perhaps a WEA alert for Aurora, CO and vicinity would be warranted just to let folks know this is not an emergency. While this is a managed situation, a 1500 acre fire with a ton of smoke would understandably freak people out.”
What is a planned prescribed burn?
A planned prescribed burn, also known as a controlled or prescribed fire, is the intentional use of fire in a specific area to manage land and reduce excess vegetation.
The burn is carefully planned and carried out by trained fire managers under suitable weather and environmental conditions. A written plan outlines the purpose of the burn, weather limits, safety measures, equipment, staffing and smoke management.
The fire is closely monitored and kept within designated boundaries to help ensure it achieves its goals safely.

Main purposes of prescribed burns
Prescribed burns are used to:
Reduce wildfire risk: Clear excess vegetation, such as dead wood, dry leaves, brush and grass, that can fuel intense wildfires.
Maintain healthy ecosystems: Restore natural fire cycles in forests and other landscapes that depend on periodic burning.
Improve wildlife habitat: Encourage native plants to grow, recycle nutrients into the soil and provide better food and shelter for wildlife.
Control invasive species: Help limit the spread of unwanted plants and promote native vegetation.
Improve forest health: Encourage new growth and improve forage for grazing animals.
