An abandoned campfire sparked the La Plata Fire burning on a Colorado 14er south of Leadville, according to a U.S. Forest Service fire investigator.

The human-caused wildfire burning on La Plata Peak, the fifth-highest peak in the state, closed access to the 14,343-foot summit after the blaze was reported Sunday. An update posted to social media Friday estimated the fire at 90 acres with 0% containment.

Scattered thunderstorms on Friday could bring “gusty, erratic winds” as the fire continued to burn in “rugged terrain with heavy dead and down timber,” the update states. But cooler temperatures and rain are also expected in the coming days.

The Interlaken Fire that last year burned more than 700 acres near Twin Lakes Recreation Area, just miles from La Plata Peak, was also caused by an abandoned campfire. 

Wildfire officials said the La Plata Fire is a reminder to anyone recreating in the backcountry to exercise extreme caution with fire and follow local fire restrictions. Campfires should never be left unattended and should be soaked until they are cool to the touch before being abandoned. 

While there were no fire restrictions in place on Friday in Lake County near the La Plata Fire, restrictions are in place throughout much of the rest of the Western Slope.
