Colorado Gov. Jared Polis declared a disaster emergency for a new wildfire Wednesday night, as others around the state grew in size.

Emergency crews working on the Crosho fire, currently at an estimated 1,700 acres — roughly 600 of which are on state and private lands in both Rio Blanco and Routt counties — will now be able to access state and federal resources, according to a Wednesday news release from Polis’ office.

The fire began Monday on Routt National Forest land before quickly spreading to private land in both counties.

The declaration is the latest in what has become a fiery few weeks on Colorado’s Western Slope. Rio Blanco County, in particular, has had its hands full with the Elk and Lee fires, which, combined, have burned nearly 136,000 acres as of Wednesday night, according to a post on the Elk and Lee Fire Information Facebook page.

Both starting about two weeks ago, the fires threatened the town of Meeker and prompted evacuation orders along Highway 13. Consistent hot, dry, windy conditions and an abundance of drought-stricken fuel has allowed the fires to spread rapidly and maintain size, despite crews’ best efforts to mitigate them.

Slight growth of state's largest fire as blaze hits 116,000 acres

The Elk fire, currently at 14,518 acres, has now reached 75% containment, according to the post. Located to the southeast of Meeker, the fire was quickly mitigated by crews, and has largely remained the same size over the past several days.

The Lee fire, currently at 127,107 acres and the fifth largest in state history, is still just 3% contained, though crews have solidified dozer lines along Meeker’s southwest corner to prevent it from spreading as close to the town as it did last week.

The reduction in containment of Lee is because as the fire acreage and perimeter grows, the percent containment decreases overall, not because any previous containment has been lost, fire officials said in a release.

Firefighters working on the Lee fire Thursday will focus on holding fire lines, as weather may challenge them. Fire officials will have a strong presence along Highway 13 to account for the predicted southwest wind.

As of Thursday morning, there are 1,274 people working on both the Elk and Lee fires combined.

Responders remain optimistic about their lines — both on the northeast end of the fire near Meeker and on the southern end closer to Rifle — and believe that, with most of its immediate fuel now burned, the fire will effectively burn itself out once the winds change back in the direction of Meeker.

Even with the optimism, critical fire weather still persists in the region, with low relative humidity and windy conditions expected over the coming days, according to the authorities.

Thursday is another Red Flag Warning day, meaning that the steady hot and dry conditions can cause larger plume growth.

Both state and federal resources have assisted in fighting the twin fires, including several National Guard aircraft and unmanned drones. 

Officials have created a fire information Facebook page where they will be posting updates about the Elk and Lee fires.
