Porcupine Fire 7.17.2021Image options: [ Full Size ]

The Porcupine Fire is one of multiple fires burning in Yosemite National Park. These fires began as a result of thunderstorm and lightning activity that moved through the park beginning  in late June 2021. This fire is being managed based on its location, potential impacts, and other key factors. Many of the fires are burning in high elevation wilderness areas, ranging from 7,000 to 9,700 feet.

The Porcupine Fire is 10 acres. Crews are monitoring this fire and it is 100% contained. Managers expect additional fires to extinguish naturally due to location and a lack of fuels. This fire may be visible from numerous vantage points throughout the park, including Tioga Road, Glacier Point, and other high-country viewpoints. Travelers on Tioga Road may see equipment and fire personnel working near the roadway in the White Wolf area to Mc Swain Summit. 

Yosemite National Park is a fire-adapted ecosystem. The strategy for all fires is to provide for the safety of employees and the public and protect natural and cultural resources. Currently, there are no threats to infrastructure.
