Air Quality & Wildfire News — June 29, 2026

Hot, dry, windy weather has fueled an outbreak of wildfires across the western United States, and the weekend brought hard news from Colorado: three firefighters were killed and two more were hurt. Several new fires are spreading quickly and pushing smoke into nearby communities.

Three firefighters killed near the Colorado-Utah border

Three firefighters were killed and two others were burned during a "burnover" on Saturday in Mesa County, near the Colorado-Utah border, UPI reports. A burnover happens when a fire spreads and closes off escape routes; the firefighters deployed emergency shelters. They worked for the U.S. Wildland Fire Service and U.S. Forest Service as part of an interagency response.

Colorado Gov. Jared Polis said he was "devastated about the loss of three heroic firefighters who died in the line of duty in Western Colorado," and activated the State Emergency Operations Plan. The Snyder-Mesa Fire was estimated at more than 28,000 acres on Sunday, and the two surviving firefighters were extracted by helicopter. The identities of those who died were not immediately released. Arkansas Online notes temperatures in nearby Grand Junction hit 93 degrees with winds gusting to 44 mph.

Willow Fire near Leadville grows to more than 1,000 acres

A wildfire dubbed the Willow Fire grew to more than 1,000 acres within hours on Sunday afternoon near Leadville, The Aspen Times reports. It ignited around 3:30 p.m. on U.S. Forest Service land below Mount Massive, about two miles northwest of the Leadville National Fish Hatchery, and prompted mandatory evacuations around Turquoise Lake.

Smoke from the fire rolled into Summit County and was visible from Pitkin County by early evening. Officials asked residents not to call 911 unless they could see a defined column of smoke or flames. When smoke is visible like this, it's a reasonable time to keep windows closed and check conditions before spending a long stretch outdoors.

Evacuations near Aspen Acres in Custer County

A separate wildfire near the Aspen Acres neighborhood in Custer County prompted a fire chief to order immediate evacuations, according to KRDO. Residents from Aspen Acres along Highway 165 to Old San Isabel Road were asked to leave, and several fire agencies were dispatched to the scene. Officials described it as a developing situation.

Xcel fixes wildfire-prevention setting blamed for Arvada outages

Not all wildfire news is about active fires. In west Arvada, residents of the Maple Valley neighborhood dealt with repeated power outages over about two weeks, and Xcel Energy said the cause was overly sensitive safety settings on wildfire-reduction equipment, The Denver Post reports. The technology is designed to cut the flow of electricity quickly if an object touches a line, reducing the chance of a spark. Xcel said its crews adjusted the settings, which had been triggered by higher summer demand.
