PARK COUNTY, COLO. -- Pike National Forest officials said the fire burning in Park County west of Lake George is now 60 acres, about twice as big as it was when crews got on scene Saturday.

Officials said they'll have a better idea about size and containment of what they're calling the 'Weber Fire' once they set up containment lines but said it is about 20 percent contained as of Sunday night.

The area of the forest burning is about three miles north of Wilkerson Pass Overlook and about 19 miles west of Lake George.

Firefighters are hoping to contain the perimeter Monday. There are still about 40 firefighters on scene.

Crews said people may see smoke until the fire is completely out. The cause is still under investigation.
