Wildfire Outbreak in Yosemite: Dome Fire Sparks Near Chilnualna Falls Trail

WAWONA — A vegetation fire broke out in the wilderness area of Yosemite National Park north of Wawona Dome, prompting swift deployment of air and ground firefighting crews. Dubbed the "Dome Fire," the blaze ignited near the popular Chilnualna Falls Trailhead in Mariposa County, sending a visible plume of smoke towering over the southern region of the park.

According to initial reports from park officials and incident commanders, the flames are actively burning through standing timber, heavy timber litter, and dense woody shrubs. Aligned with local terrain and terrain winds, the fire has demonstrated a moderate rate of spread as it moves up steep slopes primarily to the north and northeast, away from the nearby community of Wawona.

Federal and state fire agencies, including ground hand crews and aerial tankers, were immediately dispatched to establish control lines. Firefighters are leveraging natural granite barriers while securing containment lines along the southern and western perimeters to prevent the fire from shifting toward inhabited structures or park infrastructure.

Authorities confirmed that there are no immediate threats to developed areas or historic park sites at this time. However, visitors planning to hike in the Wawona and Chilnualna Falls areas are advised to check current trail closures and air quality advisories before heading out. The official cause of the ignition remains under active investigation by National Park Service officials.

Incident management teams have instituted precautionary trail closures along the Chilnualna Falls access routes and adjacent backcountry paths to keep recreational hikers safe and clear vital access corridors for emergency personnel. Water-dropping helicopters and air tankers continue to make tactical drops along the upper ridgelines to suppress spot fires sparked by wind-blown embers ahead of the main flame front.

Park meteorologists expect dry conditions and localized canyon winds to persist over the next 48 hours, creating challenging conditions for frontline containment efforts. Yosemite officials urge all park visitors to adhere strictly to regional fire restrictions, avoid unauthorized drone use near active flight corridors, and monitor official park bulletins for real-time updates on air quality and wilderness access.
