Lightning started the Derby Fire Monday morning, about 14 miles north of Dotsero in the White River National Forest. The fire gained ground from burning debris rolling down the steep terrain Tuesday afternoon.

Denver7 is tracking several other wildfires on Colorado's Western Slope. Below is our roundup on where each one is burning, containment amounts and where residents can learn more details.

On Aug. 14, Colorado Gov. Jared Polis signed an executive order declaring a disaster emergency due to the critical fire weather conditions.

As of Monday morning, the Crosho Fire was still threatening 240 structures, according to the Wyoming Type 3 Incident Management Team. However, none had been destroyed as of 9 a.m.

Over the weekend, some evacuation orders were lifted and residents were allowed to return home. Fire Zone 2 remains under evacuation, as of noon Monday.

"Moderate" fire behavior continues on the north side of the Crosho Fire, near South Spronks Creek, the incident management team said. Aerial operations will continue on Monday, along with work on the ground, to secure sections of fireline from Crosho Lake east along County Road 15. The steep terrain around the fire continues to pose a challenge, the management team said.

"Protecting the safety of both firefighters and the public remains the highest priority. Hand crews and dozers, supported by aerial resources, are carrying out full suppression efforts," the team said.

Cool temperatures, calm winds and light precipitation over the weekend helped firefighters gain some containment. This week will stay warmer and drier, which may increase fire activity.

An emergency closure order is in place for the Medicine Bow-Routt National Forests around the fire. The Routt County Emergency Incident Map is updated with road closures.

Containment: 10%
First reported: July 28

Evacuations 🏠: No current evacuations

A warming and drying trend in the weather is expected over the Stoner Mesa Fire on Monday, so there is an increased risk in fire activity.

"Firefighters continue to make good progress on containment lines in areas where the fire has been the most active while continuing to scout for opportunities for indirect containment lines in inaccessible parts of the fire," the incident management team said.

Operations Section Chief Matt Weakland with Rocky Mountain Incident Management Team 1 provided an update on Facebook on Monday. He warned that the community of Stoner, just southwest of the fire's perimeter, will see an increased number of fire personnel over the next few days as firefighters ensure that side of the fire is "very well taken care of." Recently, that has been the most active part of the fire. It will continue to be active over the next few days, he said.

The Stoner Fire is 8,523 acres as of Aug. 18, 2025 at noon.

"We're putting a lot of focus on building our lines through here and taking care of this Stoner Creek drainage," he said.

The northeast edge of the fire is in a very challenging area, he explained. The team is still planning how it will attack that area. The opposite side, on the northwest edge, is moving into the mopup stage, which will take several days before authorities can officially call it contained there.

Along the southern edge, more mopup work will continue this week, but "things are looking really good on this portion of the fire," Weakland said.

On Monday, crews will continue to patrol the western perimeter of this fire to extinguish hotspots, while others address heat pockets along the southern edge. They continue to make steady progress, according to Northern Rockies Incident Management Team 3.

Residents who live nearby may see some smoke on Monday as the fire reaches isolated pockets of unburned foliage within the perimeter. This smoke will help firefighters quickly identify and extinguish those spots.

"Spread potential is minimal, as winds are expected to remain light," the management team reported. "However, as warm, dry conditions persist through the week, residents could see increased smoke from the fire."

Winds are expected to stay light, with some gusts up to 15 mph.
