YOSEMITE – There are currently four fires burning in Yosemite. One is being actively suppressed, while the other three are being closely monitored.
Tenaya Fire (37 46.091 x 119 34.641 – Mariposa Co., 7200’ El. 8/7). The estimated acreage on the Tenaya Fire is now 415 acres with 90 percent containment. The change in estimated size is due to more accurate mapping by firefighters hiking the perimeter. This wildfire began on the afternoon of 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 fire continues to creep through surface fuels and the understory of trees. No new spot fires have been found. The firefighter efforts at the heel or anchor point continue to hold as they make good progress along both flanks of the fire. There were no air tanker flights yesterday.
Fire activities include light mop-up to hold and secure the fire line. Firefighters are adhering to Minimum Impact Suppression Techniques (MIST). They are looking for opportunities to tie fire line into granite rock, trails, and other natural barriers with the least impacts to the environment, cultural and historical features. Snags (standing dead trees), which are safety hazards to firefighters by falling, are being preserved when possible. Yosemite Resource Advisors are assigned to the fire to assist firefighters.
There are 103 personnel currently assigned to the incident, and resource demobilization will continue over the next few days. Assisting organizations and cooperators include the US Forest Service, Bureau of Land Management, and other National Park Service resources.
Risks include firefighter and visitor safety, and to the Tioga Road. Fire officials have determined that a closure of Tioga Road would negatively affect the local communities that rely on park visitation, including the communities of Lee Vining, Mammoth Lakes, Groveland and Mariposa.
There have been two minor injuries. There is no threat to structures. Estimated containment date is Wednesday Sept. 16, at approximately 12 a.m. The cause is being investigated.
Yosemite National Park thanks all fire crews, engines, pilots and overhead who responded to the Tenaya Fire.
A Safety Closure, issued by the park superintendent, is in place, and will remain in place until rescinded.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 – please adhere to their warnings of exclusion. Currently no roads are closed within the park.
Other fires being monitored:
Cathedral Fire (37 51.078 x 119 25.120 – Tuolumne Co., 9400’El., 8/2). This is near the John Muir Trail to Cathedral Lakes. The perimeter is actively smoldering and creeping through lodgepole pine needles and logs and has good potential to grow until it hits natural barriers. The fire is 37 acres.
Middle Fire (37 51.538 x 119 41.194 – Tuolumne Co., 8043’El., 7/27). It is west of White Wolf and south of the Middle Tuolumne River, and is estimated at 71 acres. Yosemite Fire Crew 1 and Saguaro Wildland Fire Module are assigned to this fire.
White Cascade (37 54.926 x 119 23.780 – Tuolumne Co, at 9000’ el., 7/3). This remote fire is within Tuolumne Meadows and is approximately 30 acres.
All visitors are urged to be diligent in any use of fire, including smoking. And be sure all fires are out! As with all fires, staff and visitor safety is of paramount importance. Each fire, regardless of size, is assessed for the appropriate course of action.
Yosemite, as other mountain areas, continues to experience air quality impacts due to regional fires. Mariposa County Health Department/Air Pollution Control District has issued an Air Quality Alert. This alert extends throughout the entire Central Valley of California. Smoke levels are in the Unhealthy Range. The County suggests remaining indoors or minimizing outdoor activities as much as possible, as smokey conditions are expected to continue through the next several days.
