Above: Yosemite Meadow Fire Time-lapse by QT Luong. "The opening sequence presents an unusual sunrise view in a smoke-filled Yosemite Valley. The remaining clips, made at Glacier Point, show the fires on the nights of Sept 8 and Sept 9, separated by a smoky sunrise. Notice how due to vigorous fire-fighting the intensity had diminished within a day."
