As of Thursday, no evacuation warnings are in place, though fire danger remains high. Trail closures have been lifted, but Perins State Wildlife Area will stay closed through July to protect sensitive wildlife.

The fire’s cause is under investigation, however, fire officials previously confirmed that they believe the fire wasstarted by a person or people.
Menkhaven Fire
The Menkhaven Fire remains at 242 acres. Containment on the fire burning approximately 7 miles northwest of Fox Creek was up to 65% as of Thursday afternoon. By Saturday, containment was up to 90%.
The multi mission aircraft conducted an infrared reconnaissance mission on Wednesday, which will provide ground crews with information on residual heat locations that could pose a threat to control lines. The fire has stopped spreading, and firefighters have been working on mop up along the perimeters. Officials said they'll begin demobilizing crews Friday evening.
