A wildfire burning near Leadville on Saturday has consumed up to 100 acres, local fire officials confirmed.
Firefighters from Copper Mountain Fire District as well the Leadville/Lake County Fire Department and U.S. Forest Service crews were attacking the blaze - called the Treasure fire - on the west side of the Tenmile Range off state Highway 91 in the San Isabel National Forest.
The fire is located in an area known as Birdseye Gulch, six miles outside Leadville, according to the Leadville Herald Democrat. The cause of the fire has yet to be determined.
Extra firefighting personnel also were on hand in Summit County late in the day Saturday, with incoming reports of falling ash.
"With fire danger at extreme levels, all Summit County resources are on high alert," battalion chief Neil Rosenberger stated in a release from the Red White and Blue Fire Protection District.
One helicopter had also been called in to assist with the fire.
The Summit County Dispatch Center was reportedly overwhelmed with calls reporting smoke Saturday evening and was urging the public to call 911 only to report new smoke sightings.
The blaze broke out as other fires started and existing ones grew across the state, with the whole of the Western Slope under a red-flag warning, indicating critical fire conditions.
A fire in Montezuma County tripled in size to 2,500 acres, while another fire near Estes Park scorched at least 16 homes, according to reports Saturday. The High Park fire, near Fort Collins, has now grown to more than 75,000 acres, making it the second-largest blaze in Colorado history.
A statewide fire ban is currently in effect prohibiting all private fireworks displays and most open fires, with a few exceptions.
