A prescribed fire Thursday in the Maury Mountains that jumped to private ranch lands and turned into a fire suppression effort had reached about 1,555 acres and was 35 percent contained by Sunday night.

The Ochoco National Forest’s prescribed fire — meant to improve natural resources within a 333-acre area near Elkhorn campground and Forest Road 16 — had headed north to private ranch lands Thursday afternoon after the wind changed direction. Of the total acreage on Sunday night, private land totaled 90 acres.

Firefighters, private land owners, Oregon Department of Forestry and the Post-Paulina Rural Rangeland Protection Association have been fighting the blaze. The U.S. Forest Service closed national forest land in the area to keep hunters and other visitors from entering during the firefighting.

Patrick Lair, spokesman for Ochoco National Forest and Crooked River National Grasslands, noted Sunday evening’s colder temperatures and forecasts of rain, saying he did not expect the fire to move further.

“Things are looking pretty good,” Lair said.

He reported no injuries, evacuations or structure damage. But deer season opened this weekend and part of the national forest at Maury Mountains — east of Forest Road 17 — remained closed. That includes the Maury Agate Bed, a rockhounding site, and one campground, Elkhorn Campground.
