Yosemite National Park Fire Managers are planning a prescribed fire in Yosemite National Park on or before Wednesday, October 28, 2015, weather and conditions permitting. There are two locations being considered for this prescribed burn and the final decision will be based on weather and air quality conditions. The prescribed burn will either occur in the Mariposa Grove of Giant Sequoias or an area along the Wawona Road near the South Entrance of the park.
