BOULDER COUNTY, Colo. — A small wildfire that prompted evacuations in Boulder County last week was sparked by a weed wacker, the sheriff's office said.

The wildfire burned about 19 acres on private land just off Highway 36 north of Boulder Thursday afternoon. The sheriff's office said the only damage from the fire was to about 100 to 150 feet of a wooden fence.
The evacuation zone for the fire spanned from Lefthand Canyon Road on the south to Nelson Road on the north. Heil Valley Ranch was on the west side.
The fire was first reported around 2 p.m. and was fully contained by 5:30 p.m. Thursday.
Investigators determined the fire started when the motor of a weed wacker started sparking and ignited nearby grass. The sheriff's office said since the fire was accidental, no charges will be filed.
