Yosemite Fire Updates

YOSEMITE – Sept. 25, 2020 – There are multiple fires burning in Yosemite National Park. Each fire is burning in Wilderness, in a fire adapted ecosystem. There are multiple trail closures in effect around Yosemite Creek and the southern part of the park. All fires may be visible from Tioga Road (Highway 120 through Yosemite National Park), Glacier Point, and high country vistas. Smoke from each fire is settling locally at night and in the morning then rising and dispersing to the north and northeast in the early afternoon. Park managers are working with the local Air Quality Districts to monitor smoke impacts to the park and local communities. Smoke from ongoing Southern and Central Sierra fires continue to impact the area.
Blue Jay Fire
Location: 4 miles south of White Wolf Campground and 1 mile west of Lukens Lake Trail at approximately 9,000 feet elevation.
Discovery Date: July 24, 2020
Size: 4,498 acres
Containment: 50%
Strategy: Confine and Contain
Cause: Lightning
Activity has diminished substantially due to cooler weather conditions and smoke inversion in the area. Primary direction of growth is to the north and northwest from Tioga Road at McSwain Summit. Unmanned Aircraft Systems (UAS) support for aerial reconnaissance and mapping, Infrared Detection (IR), and aerial ignition concluded this week. UAS support benefited firefighting operations immensely where firefighters could not access terrain on foot.
