Burnout operations have given firefighters the upper hand as they battle the last active fire of the High Cascades Complex of wildfires that have burned more than 108,000 acres on the Warm Springs Indian Reservation over the past three weeks, officials said Sunday.

The Shadow Lake fire is now mapped at 10,500 acres. It’s burning in a wilderness area15 miles northwest of Sisters.   The weather this week is expected to be more cooperative for those fighting the fire. That fire is now 25% contained. Much of the new acreage over the weekend is due to intentional burning to establish fire lines.
