HISTORY: The Sugarloaf Fire started on Thursday, June 28, 2018 from a lightning strike near the South Fork of Darling Creek, just south of Byers Peak Wilderness. The area is rugged and steep, remote with no roads and no safety zones for firefighters. It is part of the Mountain Pine Beetle “bug kill” that devastated lodgepole pine forests 20 years ago in various parts of the Forest. The numerous dead trees still standing now present a particularly dangerous condition from extreme overhead hazards and high potential for sudden and unexpected tree fall.

Management: Type 4 Incident Management Team, Incident Commander Eric Stuart

The Sugarloaf Fire is being managed under a suppression strategy. The number one goal is to protect the public and firefighters, followed by protection of private and public property and infrastructure.

Size: 1,280 acres Contained: 35%

Resources Assigned: 37 personnel; 1 Engine; 1 Type-3 Helicopter; 1 Type-1 Helicopter

Weather: From the National Weather Service Denver/Boulder – Today will be sunny, with a high near 86. Calm wind becoming west northwest around 6 mph in the afternoon. Saturday there’s a 30 percent chance of showers and thunderstorms in the afternoon. Partly sunny, with a high near 85. Calm wind becoming west southwest 5 to 7 mph in the afternoon.


Fire activity was minimal with no growth Wednesday and Thursday on the Sugarloaf Fire, even with drier conditions and gusty winds. The fire continues to smolder with some single tree torching within the perimeter, but mostly consuming ground debris and vegetation. Observation of fire activity came from a reconnaissance flight taken Thursday afternoon. During early morning hours, light wispy smoke may be visible from the surrounding area. Two fire crews remain camped out near the fire, monitoring, and patrolling the fire daily, testing pumps and hoses for structure protection purposes. Closures are being reevaluated and will stay in effect until further notice.

All structure protection for the homes and mine infrastructure has been completed. 6,000 feet of hose lay is in place and will remain so until the Sugarloaf Fire is no longer a threat. The fire is not immediately threatening homes or businesses.

An update will be posted every other morning unless fire activity changes.

Significant Events

Minimal; single tree torching; backing; flanking


Planned Actions

The water system placed around the structures (Trails End Ranch and Ute Park Ranch) will continue to be inspected and tested to ensure they are ready should the need for them arrive. Continue monitoring the fire in Darling Creek and the side drainage to the west. The Type-1 helicopter will continue to be used for water delivery should it become necessary.

Projected Incident Activity

With the existing weather conditions, the fire has slowed its spread, but it continues to creep

and smolder, back down slopes with some single tree torching. With fire behavior today, we

expect the fire to continue to spread in the upper reaches of the Darling Creek drainage. If the

fire crosses Darling Creek we can expect increased fire behavior and growth.


Today at noon, management of the fire will transition to a Type 4 Incident Management Team
