YOSEMITE – The Tenaya Fire is now estimated at 455 acres with 25 percent containment. The fire began on the afternoon of Monday, Sept. 7, and is being suppressed. It is located along the Lehamite Creek Trail from the north rim of the Valley to the Tioga Road.
The Incident Commander notes that fire activity has moderated today, as it continues to flank across slopes and creep through surface fuels as well as the understory of trees. Single tree torching was also noted. Short range spotting was observed due to variable winds; however firefighters and helicopter water drops were able to put these out.
The firefighters are making good progress from the heel, or anchor point, and along both flanks of the fire. The efforts of crews have helped to reduce the need for air tanker operations.
Although fire retardant has been employed in the suppression of the Tenaya Fire, firefighters are adhering to Minimum Impact Suppression Techniques (MIST). They are looking for opportunities to tie firelines into granite rock, trails, and other natural barriers with the least impacts to the environment, cultural and historical features.
Assisting organizations and cooperators include the US Forest Service, Bureau of Land Management, and other National Park Service resources. There are 241 personnel committed to the fire.
Risks include firefighter and visitor safety, and to the Tioga Road. A closure of the road would negatively affect the local communities that rely on park visitation, including the communities of Lee Vining, Mammoth Lakes, Groveland and Mariposa.
There has been one minor injury. There is no threat to structures, and no estimate for full containment. The cause is being investigated.
A Safety Closure, issued by the park superintendent, is in place, and will remain so until rescinded. All trails on the north rim of Yosemite Valley south of the Tioga Road and east of Yosemite Creek are closed. Trail blocks are in place, and Park officials ask everyone to please adhere to their warnings of exclusion.
Currently no roads are closed within the park.
