Firefighters in the air and on the ground battled a 122-acre wildfire Saturday that broke out near the National Center for Atmospheric Research in Boulder
threatening neighborhoods on the southwestern edge of the city and forcing thousands of people to evacuate.
Officials scaled back evacuations after 11 p.m., allowing residents in parts of south Boulder and unincorporated Boulder County back into their homes.
Boulder Fire-Rescue spokeswoman Marya Washburn told the Daily Camera that about 1,600 to 1,900 homes remained in the evacuation area, down from 8,000 homes.
Colorado 93 was closed in the late afternoon in both directions from Colorado 128, near Superior, to Marshall Road because of the fire, according to the Colorado Department of Transportation.
