It is spreading southeast and was spotted slightly after 1 p.m. Tuesday by Susan Newton in the Bryant Mountain Lookout, Russell Betts, fire information officer for the BLM said. No populated areas have been burned or are in the way. The fire is about a quarter-mile away from the Bryant Mountain Lookout, which has been evacuated."

July 9, 1981: " Two years after it was destroyed in a forest fire the Bryant Mountain Lookout is back in operation. The first tower, a two-story building, was destroyed in the 1979 Bryant Mountain fire. The new tower was built by Johnson Construction of Klamath Falls at a cost of about $90,000, Bob Soule of the Bureau of Land Management Lakeview office reported. The tower was under construction for about a year, he said. However, considerably less actual construction time was involved. The new tower stands 30 feet tall on Loveness Timber Co. property about 50 yards away from the old tower site. The lookout lives in the tower, in contrast to some towers where living quarters are at the tower base. Soule said the move enables the lookout to see a good deal more territory. The lookout moved into the tower in June, Soule said, and is expected to leave in early October. When the first Bryant Mountain Lookout was opened, a lookout on Yainax Butte was closed. Other lookouts that cover territory observed by the Bryant facility include Horsefly and Hogback lookouts." (Herald and News)
