Tenaya Fire fully contained

One of four wildfires inside Yosemite National Park was fully contained this week, while strong progress is being made on the remaining blazes.

The Tenaya Fire, which started Sept. 7 along the Lehamite Creek Trail at the north rim of Yosemite Valley, was 100% contained at 415 acres Wednesday.

More than 160 firefighters are at work to demobilize resources, keep the fire within its containment lines, and clean up the burned area, assisted by the U.S. Forest Service, Bureau of Land Management, and other National Park Service resources.

Two minor injuries were reported from fighting the fire, with no threats to structures. The cause of the Tenaya Fire is being investigated.

Multiple trail closures were lifted as a result, though safety advisories are in effect.

Three other fires, caused by lightning, continue to burn within the park, per the latest updates provided by park officials.

The Cathedral Fire, near the John Muir Trail to Cathedral Lakes, was at 37 acres, though it has good potential to grow until it hits natural barriers with its perimeter smoldering and creeping through lodgepole pine needles and logs.

The Middle Fire, west of White Wolf and south of the Middle Tuolumne River, is at 71 acres. Yosemite Fire Crew 1 and Saguaro Wildland Fire Module are assigned to stop its progress.

The White Cascade Fire, a remote blaze in Tuolumne Meadows, is at an approximate 30 acres.

All visitors are urged to be diligent in any use of fire, including smoking, and ensure all fires are completely out.

An Air Quality Alert remains in the park and throughout the Central Valley from the Mariposa County Health Department/Air Pollution Control District due to smoke from the flames.
