Crews are working to mop up a fast-moving grass fire in Boulder County that destroyed four structures and prompted 75 homes to be evacuated Monday.
Wind gusts reached nearly 70 mph early Tuesday morning as firefighters worked to control what's been dubbed the Rabbit Mountain Fire. It is now 100 percent contained, though high winds are a concern, according to the Boulder County Sheriff's Office.
The blaze started around 5 p.m. Monday at 6300 Ute Highway, and about 150 acres have burned so far.
The Boulder County Sheriff's Office says no homes were lost. As of 4:30 a.m., there was no estimate on containment, but firefighters say the blaze is not growing or spreading, and that crews are working to contain hot spots.
