LARIMER COUNTY, Colo. — The largest fire in Colorado history, which has been burning for more than two months in Larimer County, is 55% contained, fire officials said Thursday morning.

As of the latest available information, the Cameron Peak Fire is 206,977 acres.

Helicopters were able to slow the fire's progression with water and retardant drops on Wednesday, according to the Rocky Mountain Type 1 Incident Management Team. Meanwhile, crews on the ground continued their work constructing and reinforcing control lines on the fire's southern edge, and setting up protections for structures in The Retreat and Storm Mountain communities.

Air support was grounded over the Cameron Peak Fire in the late afternoon Wednesday because the smoke from the 125,000-acre East Troublesome Fire hovered over the Cameron Peak Fire, causing poor visibility, the incident management team said. Fire officials from both mountains are communicating and working together as needed. The fires' edges are about 11 miles from each other as the crow flies at their closest points.

The northern and western side of the fire remained secure Wednesday.

Crews also made "excellent progress" along the fire's northeast edges and on Buckhorn Road and County Road 27, the incident management team said. Containment lines are nearly complete in this area.

Division T, U and V also were successful in constructing and enforcing fire lines on Wednesday.

Fire activity increased in Branch III, along the central-southern edge of the fire, officials said. Crews working in Division Y continued building a direct line from County Road 27 west toward Cedar Park. Just west of this area, firefighters are monitoring growth from Bulwark Ridge to County Road 43, the incident management team said.

Supervisors are scouting out the best ways to construct a direct line in the tough terrain that would help deflect the fire from Storm Mountain.

Fire officials are continuing to staff the fire 24/7.

A group focused on structure protection at Pingree Park and the CSU campus are monitoring the fire and working to mop up as needed. A new structure protection group is focusing on at-risk values along County Road 43, the incident management team said.

Multiple locations around the edges of the fire are under voluntary or mandatory evacuations. For details, view the evacuations in the map below, or go here for the full list of evacuations and closures. You can also call 970-980-2500.

Near-critical weather conditions will continue Thursday morning ahead of a cold front, which is expected to reach the area by the afternoon. The front will bring in cooler temperatures, wind and increased humidity.

On the fire's Facebook page on Thursday morning, officials said suppressing the blaze is a group effort between fire agencies, Arapaho and Roosevelt National Forests, Rocky Mountain National Park, sheriff's offices, the American Red Cross and more.

"There are so many partners working together on this fire that any list will inevitably leave someone out," the post reads. "But one critical partner we want to make sure we don’t leave out is you, the public citizens of this area. Your support of our firefighting efforts makes a world of difference to us. Your understanding of being out of your homes, your tolerance of the smoke and firefighter traffic, your words of encouragement and support, and your monetary support of local fire departments and charitable organizations makes us all feel like we’re a part of your communities and one big collective family. Thank you all. We will beat this fire — together."
