Firefighters made progress Sunday on the Horse Mountain fire burning on federal forestland 17 miles southwest of Grants Pass, and hope to put a containment line around the fire by Sept. 1.

The fire grew to 645 acres and was about 50 percent contained, according to information posted on the information site, www.inciweb.org.

Fire bosses have committed 672 personnel to the campaign, including nine interagency Hot Shot crews, 14 additional 20-person crews, seven helicopters, 10 engines, four dozers and seven water tenders

Three area recreation sites remain closed: Bolan Lake campground, Lake Selmac campground and Spalding Pond campground.

Fire bosses hope to stop the fire by building containment lines and then igniting the area between the fire and the containment lines, thereby depriving the fire of fuel. Burnouts will have to wait for favorable weather, according to the inciweb report.

Forecasters are expecting cooler temperatures and moist marine air to prevail over the fire area today and Tuesday as a weak weather system moves onshore.
