CHAMBERSBURG – Fire crews from the Pennsylvania Department of Conservation and Natural Resources Bureau of Forestry, supported by area fire departments and mutual aid partners, have placed the Mountain Fire northeast of Chambersburg under control as of Tuesday afternoon.
As of 2 p.m. April 14, current mapping indicates the wildfire has burned approximately 73 acres. The fire, which began the afternoon of Saturday, April 11 near Knob Road, no longer poses an active spread risk. Officials said forward progression was stopped earlier, and crews are now reinforcing containment lines and addressing isolated areas of smoldering.
Although full extinguishment has not yet been declared, officials emphasized that ongoing monitoring continues around the burn area. Residual heat and minor rekindling remain possible within the fire perimeter, but firefighters are closely watching conditions.
Residents may notice light smoke, especially during temperature inversions or shifting winds. Ridge Road remains temporarily closed to ensure safe access for fire personnel and equipment.
Investigators have not yet determined the cause of the fire. Forestry and fire crews used a combination of hand tools, heavy equipment, and natural barriers to secure control lines. Officials credited public cooperation with road closures for helping maintain safety throughout suppression operations.
State and local agencies will continue to monitor weather conditions — including wind and humidity — for any potential influence on fire behavior and promised to provide further updates as necessary.
