Yosemite Fire Updates

YOSEMITE – Sept. 18, 2020 – There are multiple fires burning in Yosemite National Park. Each fire is burning in the Ansel Adams 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. Heavy smoke from the Creek Fire continues to impact the area resulting in the closure of Yosemite National Park until Sept. 25, 2020 at which time the conditions will be re-evaluated.

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: 4,061 acres
Containment: 40%
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. Spotting north of Tioga Road is smoldering and creeping, with occasional small group torching. Fire crews are utilizing Unmanned Aircraft Systems (UAS) for aerial reconnaissance and mapping, Infrared Detection (IR), and aerial ignition. This type of aerial ignition aids fire personnel by gaining depth along natural containment lines in areas that firefighters cannot access on foot.
