The latest mapping on the Shadow Lake Fire, 15 miles northwest of Sisters, shows noticeable growth. Yesterday the fire moved one and a half miles to the west and its now within four miles of Highway 126. Its’ total size is now at almost 5500 acres, up about 900 acres from the day before. And with a very hot and dry weather system moving in, chances are things will get worse. Fire spokesperson Kristen Bowles says the fire is so dangerous to fight and in such a remote area, that they decided to let parts of the fire just burn out naturally: "This fire's going to burn until we have what we call a season ending event, rain or snow, within the perimeter of where fire-fighters are. Where the fire has come to the edge of our fire lines they are going to be mopping up. Mopping up hot spots. But as far as the interior part of the fire we don't have any resources on that - its going to continue to burn until it goes out on its own." Fire crews are trying to keep the fire within the wilderness and out of the Clear Lake area; they are using helicopters and tankers to slow its most toward the west, and they may even use the lava fields as part of a fire line.
