Fire crews and deputies were called to what they called a "fast-moving wildfire" located just south of the Denver Metro Area on Sunday night.

According to the Douglas County Sheriff's Office, the fire broke out in the area near 2903 Bears Den Drive, which lies approximately three miles southwest of Sedalia.

The sheriff's office posted on around 8:30 p.m. that its deputies are working with South Metro Fire Rescue, Castle Rock Fire Department and West Douglas Fire Protection to bring the fire under control. They said that crews were "working on structure protection with heavy fire in brush and shrub oak."

At 10 p.m., officials provided an update, stating that crews at the scene have managed to stop the forward progress of the fire. Initial estimates stated the fire had covered 2 1/2 acres, but as crews gained control of the blaze, officials shared that the fire was contained to one acre.

The sheriff's office spoke with the media Sunday night, stating that the fire came dangerously close to at least one home, and four homes had to be evacuated. Those evacuation orders have since been lifted, and the families affected are able to return home. No structures were damaged in the fire, they added.

The cause of the fire remains under investigation, and crews will remain on the scene throughout the night as they continue to mop up.
