The Lions Fire showed no growth yesterday, and continues to be 4,000 acres and 60% contained. Crews remaining on the fire are reinforcing and securing the fireline, in order to ensure that it will hold as conditions become drier and hotter throughout the summer. Higher winds are projected for today and tomorrow, and crews are monitoring for threats to the line or spot fires. There are still unburned pockets of fuel within the unit, which will continue to be consumed in the coming weeks. A small amount of smoke production is likely to continue during this process, without creating significant impacts for nearby communities.
Air quality in Mammoth Lakes and the surrounding areas is expected to continue to be slightly affected by smoke from larger wildfires elsewhere in the state, such as the County Fire in Yolo County, CA. Residents and visitors are advised to limit their exertion outdoors should periods of heavy smoke occur.
As the need for active firefighting decreases, firefighters are reducing the impacts that fire operations have had upon the wilderness character of the area, a process known as “suppression repair.” Techniques may include repairing damaged trails, clearing cut trees and brush, or creating simple drainage structures to prevent erosion.
Located between the footprints of previous fires, the Lions Fire is contributing to diverse and healthy forest ecology. The area will ultimately be more resilient in drought conditions, and better protected against future wildfires.
The following National Forest System Trails near the Lions Fire area have been temporarily closed: Sierra National Forest Trails No. 26E01 (Mammoth Trail) to the Inyo NF Boundary, 26E14, 26E56, and 26E46 from the Inyo NF boundary. Inyo NF trail closures include 26E01 from the Sierra NF to 2601 junction. Trail closures will remain in place until fire management staff determines that it is safe to reopen the area.
Shuttles to Devils Postpile National Monument and Reds Meadow Valley are running, and trails there are open. The Pacific Crest Trail and the John Muir Trail are open. Visitors should expect smoke impacts of variable intensity.
Due to decreasing fire operations, further updates will be issued only if warranted by a change in conditions.
