BUTTE FALLS — A 1,250-acre fire that roared to within a mile and a half of Butte Falls was 75 percent contained by late afternoon Friday, officials said.

Cool weather and increased humidity Friday helped efforts to bring the Double Day fire under control, said incident commander Bill Hunt, who added that the team has "a really good opportunity to really secure this fire (Sunday)."

Full containment is expected by 6 p.m. Sunday. The estimated cost of battling the fire so far has added up to nearly $865,000.

The northeast edge of the fire, which remains near Butte Falls, burned actively through Thursday night, ODF officials said.

It is burning through state-protected private lands and U.S. Bureau of Land Management lands. No evacuations have been necessary, but Salt Creek, Double Day and Hukill roads were closed to motorized traffic. Butte Falls Highway remains open, but fire-related traffic is heavy. People are asked to postpone or reroute unnecessary travel through the area.

On Friday, crews continued to focus on protecting structures and public safety as they continue aggressive suppression and mop-up work. Top priorities included protecting public water supplies, power lines, and other infrastructure, as well as spotted owl habitat and valuable timber and range lands. Piles of large-diameter downed timber that are 6 to 8 feet high have created a potentially dangerous challenge to firefighters, officials said.

An open house with Oregon Department of Forestry and Forest Service officials to answer questions about the Double Day and Lonesome fires is scheduled for 1 to 3 p.m. today at the Butte Falls Community Hall.
