YOSEMITE – Sept. 11, 2020 – There are multiple fires burning in Yosemite National Park Wilderness. Each fire is burning in a fire adapted ecosystem. There are trail closures for the Lukens Lake-Yosemite Creek and Yosemite Creek Campground trails from Tioga road to the north rim of Yosemite Valley. All fires may be visible from Tioga Road, 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 and will be monitoring smoke impacts to the park and local communities. Heavy smoke from the Creek Fire is reducing visibility and shading out the area which has moderated fire behavior.
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: 3,132 acres
Containment: 20%
Strategy: Confine and Contain
Cause: Lightning
The fire has a 70% active perimeter burning in pockets of accumulated dead and down logs and is creeping and backing with isolated single tree torching along the active perimeter. When conditions are favorable, firing operations are occurring to help bring the fire’s edge to natural containment lines. Fire crews are utilizing unmanned aircraft systems 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 otherwise too dangerous for firefighters to hike.
