The Quarry fire in Jefferson County continued to subside Sunday and hundreds of evacuated residents are returning home.

“I’m feeling really good about where we are at,” Mark Techmeyer, a spokesperson for the Jefferson County Sheriff’s Office, said during a news conference Sunday morning.

The 472 acre fire reached 35 percent containment as of Sunday afternoon after reaching 20 percent containment on Saturday.

The wildfire has remained that size for almost two days.

The Deer Creek Mesa and Kuehster neighborhoods were reopened on Saturday to residents. That includes roughly 200 of 575 evacuated homes that were under mandatory evacuation, Techmeyer said.

No structures have been damaged.

To ensure safety on Sunday afternoon, the Jefferson County Sheriff’s Office said CORE Electric would be shutting off power to some areas around the Quarry fire.

The shut off area was from the intersection of Grizzly Drive and Deer Creek Canyon Road west to South Deer Creek Canyon Road and everything south of that area for 3 miles, the sheriff’s office said.

Techmeyer described reactions from returning residents as “cheers and tears.”

Each of them must get credentials at the evacuation center at Dakota Ridge High School, 13399 W. Coal Mine Ave. Residents must show ID to receive their re-entry badge.

Techmeyer said that residents must have a credentialed badge to enter the neighborhoods.

The Quarry fire, which was human-caused and is being investigated as arson, has impacted the Deer Creek Canyon area.

Techmeyer said that the investigation remains ongoing, and that the sheriff’s office is “hitting it hard.”

“Whether it’s accidental or it was intentional, it is an arson investigation,” he said.

The fire only saw a small growth of around 30 acres over Friday evening. Luckily, the spread went toward open land, not structures. The total still sits around 480 acres.

Containment improved to around 10 percent Friday from 4 percent, but the sheriff’s office warned locals that they may see more smoke than before on Saturday due to the work the nearly 185 firefighters are completing in the area.

Authorities couldn’t provide an updated acreage count on Sunday.

“We still have the northwest area that no boots can go in, because it’s so steep,” Techmeyer said.

Firefighters will continue fighting the Quarry fire Monday morning, the sheriff’s spokesperson added.

Helicopter airdrops continued on Sunday in Jefferson County.

When asked how Sunday’s heat would impact the fire’s containment, Techmeyer said that despite it being a little warmer than Saturday, drier conditions on Sunday will cause difficulties.

But the afternoon rain storms assisted the cause, Jefferson County Sheriff’s recognized on social media platform X on Sunday.

“Anything can happen,” Techmeyer said on residents going back to their neighborhoods, emphasizing the county remains under Stage 2 no fire restrictions.

“It’s going to be busy,” he said. “And that’s why I want to really try and restrict any kind of traffic from those who do not live there.”
