Lightning across northwestern Colorado is suspected of sparking about 30 fires over the weekend, keeping firefighters running from one fire to another.
The largest of the wildfires is the Four Mile Fire, which is burning on just over 1,000 acres 20 miles north of Craig. It was 80 percent contained Monday.
Many of the smaller fires have been contained.
The Northwest Colorado Fire Management Unit says over 4,000 lightning strikes hit northwestern Colorado on Saturday and Sunday.
