Re: Yosemite Fires Update

Yosemite Fires Update

Fire activity increased over the weekend on the Grouse and Harden fires in Yosemite National Park. The Grouse Fire (250 acres) is about seven miles southwest of Yosemite Valley and north of Glacier Point Road. The Harden Fire (111 acres) is on the north side of the park, west of Harden Lake and northwest of White Wolf. The two fires are being managed to achieve both protection and resource objectives.

The objectives for the fires include preventing fire growth outside defined management areas, restoring fire dependent forest systems, managing smoke production, protecting wildlife habitat and preserving cultural and natural resources. To achieve these objectives, fire personnel employ a variety of strategies and techniques such as building fire line, blacklining control lines, using aerial resources when necessary to slow fire progression and monitoring and patrolling.

Sunday, personnel took actions on the Grouse Fire to contain a spot north of Steamboat Ridge. A helicopter dropped buckets of water while crews worked on the ground constructing hand line. On the Harden Fire, personnel scouted areas to begin containing the fire on the east and west sides to allow continued progression northward. Additional resources will arrive Monday to assist with the management of these fires. Managers are prepared for increased fire activity as hot, dry conditions continue.

Park staff continues to monitor smoke and work closely with Mariposa and Tuolumne County Air Pollution Control Districts to address air quality concerns. Managers have identified actions that will be taken to meet incident objectives and minimize impacts to the park and surrounding communities. Smoky conditions may exist from time to time within the park. Residents and visitors are advised to take precautions to minimize smoke impacts to health.

The Grouse and Harden fires in Yosemite National Park continue to move at a steady pace under hot and dry conditions. The Grouse Fire (350 acres) is about three miles southwest of Yosemite Valley and north of Glacier Point Road.

The Harden Fire (220 acres) is on the north side of the park, west of Harden Lake and northwest of White Wolf. The two fires are being managed to achieve both protection and resource objectives.

The objectives for the fires include preventing fire growth outside defined management areas, restoring fire dependent forest systems, managing smoke production, protecting wildlife habitat and preserving cultural and natural resources. To achieve these objectives, fire personnel are using a variety of strategies and techniques such as building fire line, blacklining control lines, using aerial resources when necessary and monitoring and patrolling.

Monday, on the Grouse Fire, personnel took actions along Steamboat Ridge to keep the fire within the defined management area. Crews also prepared sections of Wawona Road for future burnout operations. On the Harden Fire, personnel began fire line construction east and west of the fire to stop fire progression in those directions while allowing north and south progression to continue. In addition, helicopters dropped buckets of water on hot spots to slow fire spread and shuttled supplies for crews.

Park staff continues to monitor smoke and work closely with Mariposa and Tuolumne County Air Pollution Control Districts to address air quality concerns. Managers have implemented actions on the Grouse Fire to meet incident objectives and minimize smoke impacts to the park and surrounding communities. Smoky conditions may exist from time to time within the park, on roads and in surrounding areas. Residents and visitors are advised to take precautions to minimize smoke impacts to health.
