Firefighters were working to contain a new brushfire reported late Thursday afternoon in northwest Lake County, southeast of La Pine. The Cabin Lake Fire was reported shortly before 4 p.m. and had burned about three acres at last report, about 50 miles southeast of La Pine. It was visible over a wide area and on the University of Oregon AlertWest camera, located on Green Mountain. Crews were putting a line around the fire Thursday evening and had called in a helicopter to assist, said Lisa McNee of the South Central Oregon Fire Management Partnership. McNee said the fire was burning in grass and sagebrush on BLM land north of Fort Rock.
