Fire Nears Planned Boundary
Incident: Grouse Wildfire
Released: 7/6/2009
The Grouse and Harden fires in Yosemite National Park are nearing the boundaries that managers planned for the incidents. The Grouse Fire is three miles southwest of Yosemite Valley and north of Glacier Point Road. The Grouse Fire is 2,975 acres and 95 percent contained. The Harden Fire on the north side of the park, west of Harden Lake and northwest of White Wolf is currently 1,661 acres and 90 percent contained.
When the fires started late May and early June, officials identified areas where the fires could be managed for multiple objectives. The objectives include restoring fire dependent forest systems, reducing hazardous fuel accumulation, managing smoke production, protecting wildlife habitat and preserving cultural and natural resources. Throughout the incidents, park staff has worked closely with Mariposa and Tuolumne County Air Pollution Control Districts discussing planned operations and potential for smoke impacts to the park and outlying areas. Fire managers with every fire always consider public health, related to air quality. To see air quality data, please visit: http://www.nps.gov/yose/naturescience/aqmonitoring.htm
Even though the fires are reaching the boundaries that managers set for the incidents and the percentage contained is increasing, the fires are not out yet. Fire activity will continue within the perimeters for some time.
On the Grouse Fire Sunday, personnel worked on the southwest perimeter to connect containment lines between Wawona Road and Glacier Point Road. Due to fire activity near Wawona Road, it was necessary to limit traffic to one lane during a part of the day to ensure safety for firefighters working on the road and for park visitors traveling the road.
On the Harden Fire, personnel continued securing containment lines. With the decrease in activity on the Harden Fire, resources are being released from the assignment. Trail closures remain in effect on the Harden Fire until further notice. The trails are Smith Meadow to White Wolf and Aspen Valley to White Wolf. There is an alternate route to Pate Valley from White Wolf, which bypasses the Harden Lake area.
Personnel are working diligently to complete work on containment lines before there is a significant change in the weather mid-week. Weather forecasters advise fire officials that several low pressure systems are heading toward the area, which may bring cooler temperatures and possible strong winds.
Travelers are advised of temporary road delays and closures, due to smoke and firefighters working along the Wawona Road and the Glacier Point Road. Travelers will see fire and smoke along the roads. For firefighter and driver safety, please use caution.
