A new fire burning in the Cascade Lakes area has caused evacuations of Mount Bachelor and several nearby locations in the Cascade Lakes area. 

The Backside Fire, located west of Mount Bachelor in a roadless area, was about 80 acres by Saturday evening and forced a Level 3-Go Now evacuation notice for areas including Mount Bachelor, Todd Creek Horse Camp, Sparks Lake, Devils Lake and the Quinn Meadow area, according to the Deschutes County Sheriff’s Office. 

Level 3 means leave immediately.  

Multiple air and ground resources were responding to the fire, according to Central Oregon Fire Information, an interagency fire information site. 

Mt. Bachelor ski area spokeswoman Lauren Burke said Saturday the mountain would remain closed on Sunday due to the fire, and intended to reopen on Thursday. 

The fire was among 15 lightning-caused fire incidents on the Bend-Fort Rock Ranger District of the Deschutes National Forest that firefighters responded to on Saturday. 

The Firestone Fire, burning in brush and timber southeast of Newberry Caldera on the Deschutes National Forest, grew to more than 3,000 acres. Saturday evening, the Deschutes County Sheriff’s Office heightened evacuation levels due to this fire.
