A combine moving through a wheat field around 2:30 PM EDT overheated and started a fire that spread rapidly due to extremely dry conditions. Within minutes flames destroyed the combine estimated to be worth about $92,000 and swept eastward across a field of foot high wheat stubble. The fire was extremely intense, with flames reaching 15 feet in height. Three State Department of Forestry fire fighting units and nine volunteer fire companies from Frederick, Clarke, and Warren Counties battled the blaze. The fire was brought under control by 5:00 PM EDT and completely extinguished at 9:20 PM EDT. Six firefighters were treated for heat exhaustion at the scene during the operation. The fire ended up burning 60 acres of wheat valued at around $6,700, 5 acres of farmland, and 2 acres of woodland.
