Fire crews heave begun mop up operations on all seven fires in the High Cascades Complex. Crews conducted very successful burnout operations over the weekend, allowing crews to really get the upper hand on the fires. Mop-up means the crews start at the edge of the fires' perimeter and can work inward to find hot spots. Fire bosses say that conditions are still ripe for active fire behavior, and crews will be watching for spot fires.   Officials will analyze fire situations today and consider time frames for lifting closures that are in place. The High Cascades Complex Fires have burned about 108,000 acres.
