GUERNSEY — A fire started by National Guard soldiers during weapons training grew to 6,500 acres Thursday but had not stopped any training exercises.
The south edge of the fire, which started Tuesday, was about four miles north of Guernsey Reservoir.
More than 120 firefighters, two commercial air tankers and Wyoming Army National Guard helicopters were fighting the fire Thursday on the Camp Guernsey Joint Training Center's North Training Area.
"The terrain, winds and dry conditions make this a very complex fire scenario," said Dan Perko, deputy state forester. "It could be five to seven more days before crews are off the scene."
Lt. Col. Deanne Vogel, deputy camp commander, said officials believe a tracer round fired from an automatic weapon started the fire. Use of the tracer rounds has since been prohibited until the dry conditions improve, she said.
"Units are still training at the camp and in our North Training Area," she said.
