Lightning strikes from a passing thunderstorm are believed responsible for igniting several small wildland fires in western Boulder County late Sunday afternoon. Firefighters from several area fire departments found themselves busy responding to six separate fires and a number of smoke reports:
- A tree fire in the 2500 block of James Canyon Drive southeast of Jamestown was fully contained by 7:00 p.m. A United States Forest Service crew was on-site
- The “Cal-Wood Fire” at the Cal-Wood Ranch, 2300 block of County Road 87, north of Jamestown, burned approximately 1.5 acres of brush and grassland. It was contained and mop-up operations were in progress as of 8:00 p.m.
- A small brush fire near 400 Whispering Pines Drive off of Sugarloaf west of Boulder was quickly contained and extinguished by 6:20 p.m.
- A small brush fire near 33700 Gold Lake Road east of Ward was contained and was being mopped up by firefighters from the Indian Peaks Fire Protection District as of 7:30 p.m..
- The Blue Mountain fire northeast of Lyons near the Larimer/Boulder County Line consumed an estimated five acres of brush and grass. It was located on Boulder County Parks and Open Space Land at Rabbit Mountain and necessitated the closures of the park Sunday afternoon to facilitate firefighting traffic. A single-engine air tanker made one drop on the blaze. It was 50% contained as of 8:00 p.m.; firefighters from Berthoud, Lyons, Hygiene and Boulder County Parks and Open Space responded.
- An estimated 25 firefighters from the Lefthand Fire Protection District and adjacent fire departments responded to deal with a fire in Spring Gulch, approximately 11 miles up Lefthand Canyon from US Hwy 36. The fire had burned approximately 2-3 acres by 8:00 p.m. and was entirely on United State Forest Service property. It was 90% contained; air resources were requested to assist with fighting the fire.
Firefighters also responded to smoke reports on Caribou Road near Nederland and at the Bunce School Road/Hwy 7 intersection south of Allenspark; fortunately, those reports proved to be unfounded.
