Fire behavior is creeping and smoldering through ground litter on the forest floor and burning in pockets of accumulated dead and down logs with some isolated single tree torching and short-range spotting. The fires are expected to continue creeping and smoldering as they burn through timber litter with an overstory of lodgepole and red fir.
The North Whizz Dome Fire is being managed with a confine and contain strategy utilizing Minimum Impact Suppression Techniques (MIST) in fire adapted wilderness. There are currently no threats to infrastructure or hiking trails. The fire will be visible from Tioga Road, Glacier Point, and high-country vistas.
Smoke production is very light with minimal local impacts dispersing to the north and northeast. Park Managers are working with the local Air Quality Districts and will be monitoring smoke impacts to the park and local communities.
