KLAMATH FALLS, Ore. (AP) - Firefighters have built a partial line around a fast-growing wildfire in southern Oregon that has destroyed structures and led to dozens of evacuations, fire spokeswoman Erica Hupp said.<br />
<br />
Crews were assessing the fire near Sprague River on Monday morning. The last measurement estimated the blaze at about 4 1/2 square miles, said Hupp.<br />
<br />
The wildfire started around 2 p.m. PDT Sunday in timber and brush and has destroyed an undetermined number of homes and structures.<br />
<br />
Before sundown Sunday, Klamath County sheriff's deputies evacuated more than 100 people from homes along two roads in the area.<br />
<br />
The blaze is just one of several major fires churning through the West.<br />
<br />
In Northern California, a wildfire has burned 6 square miles of forested land and destroyed 18 structures, CalFire officials said. Authorities believe the fire was sparked by the exhaust from a truck driven by a man delivering supplies to an illegal marijuana plot.<br />
<br />
The fire burning in steep terrain was just 15 percent contained on Sunday.<br />
<br />
Meanwhile, the Mills Canyon Fire burning in central Washington has grown to 35 square miles.<br />
<br />
Firefighters strengthened containment lines around the fire near Entiat (EHN'-tee-aht) on Sunday, but they're still worried about the potential for dry lightning and wind to kick up the flames on Monday.<br />
<br />
Three dozen homes have been evacuated and residents of another 500 houses have been told to be prepared to leave if the fire gets closer.<br />
<br />
The South Central Oregon Fire Management Partnership said the wildfire near Sprague River was burning in the town's Moccasin Hill neighborhood.<br />
<br />
Hupp said crews were gathering more details about the types and numbers of structures burned, and crews are building fire lines.<br />
<br />
"There's still a lot of the fire that isn't lined," she said.<br />
<br />
The weather forecast calls for dry, hot afternoons in Washington and Oregon for the next week and that is expected to increase fire activity.<br />
<br />
"It is still actively burning," Hupp said of the Oregon fire. "We're going to see what the afternoon brings."<br />
<br />
She said that the blaze has been growing steadily because of high winds and extremely dry conditions. But fire teams were hoping that higher late-night humidity would help slow its growth.<br />
<br />
The Red Cross has set up a shelter at a community center in Sprague River, which is about 25 miles northeast of Klamath Falls.
