ROCKY MOUNTAIN NATIONAL PARK - The lightning-caused Big Meadows Fire broke out inside Rock Mountain National Park exactly one week ago. Since then, it has grown to 604 acres. No structures or communities are threatened, and the park remains open. It's now 95 percent contained.

Sunday, operations emphasized the continued reinforcement of containment lines and rehabilitation of areas where crews were required to take down trees.

Friday afternoon, fire crews conducted a burnout operation to strengthen fire lines and reduce fuels along the southern flank of the fire in the Tonahutu Creek drainage.

Early Saturday morning, closures were lifted for five of the seven previously closed trailheads within the vicinity of the Big Meadows Fire.

They include: the two Tonahutu Spur Trails (one beginning at the Kawuneeche Visitor Center, the other near the North Inlet trailhead), the Grand Lake Lodge Spur Trail, the Timber Lake Trail, and the trail which branches toward Mount Ida from Milner Pass. The Timber Lake Trail will be open for day use only.

Closures remain in effect for the Onahu Trail, the Green Mountain Trail, and the lower Tonahutu Trail. Trail closures do affect a section of the Continental Divide Trail that passes through the park.

All major roads and facilities in Rocky Mountain National Park, Grand Lake and Estes Park are open. Visitors are strongly cautioned to be aware of increased traffic and aircraft associated with the fire.
