New Mexico National Guard troops are helping support firefighters strengthening lines around the Thompson Ridge fire in northern New Mexico and mopping up hotspots within the fire's perimeter.
The fire burning in the Valle Caldera National Preserve and the Santa Fe National Forest has burned just under 33 square miles near Jemez Springs. It started May 31.
Approximately 1,000 personnel are assigned to the fire. Approximately 20 National Guard personnel are delivering supplies to firefighters.
Fire management team spokeswoman Margot Witt says containment is estimated at 40 percent.
Witt says cloud cover helped firefighters make good progress Sunday. The fire continues to be most activity on its southeast side.
State Route 4 is closed from its junction with State Route 126 to the junction with State Route 501.
