The U.S. Forest Service said the fire burned up to the tundra on the northeast side, where it laid down on Thursday night. It’s still actively burning in the Darling Creek drainage.

The agency believes it was likely caused by a lightning strike Wednesday. No structures are immediately threatened and no evacuations have been ordered.

Summit County Fire and EMS said the fire is burning on U.S. Forest Service land about 4 miles from the Summit County border near Ute Pass and the Henderson Mill.

A Type 3 Management team is expected to take control of firefighting efforts Saturday morning.

Smoke from the wildfire was visible from Interstate 70 in the Silverthorne area on Thursday.
