Firefighters battling the Reynolds Creek Fire at Glacier National Park were confronting high winds and low humidity Saturday.

While more than 60 percent of the blaze, which has burned across 3,342 acres, has been contained, the weather forecast had fire bosses concerned the fire could increase. The fire was expected to continue to burn in the Rose Creek and Two Dog drainages on the northern perimeter of the fire lines, but that was being permitted to reduce fuels there.

More than 500 firefighters were on the fire, supported by a dozen fire engines and seven helicopters for water drops.

Still closed due to the fire were the Rising Sun Motor Inn and the Rising Sun Campground. The Going-to-the-Sun Road also was closed from St. Mary to Logan Pass. While the pass was accessible from the west side of the park, officials were urging visitors to take advantage of the park shuttle buses due to congestion and a lack of parking space. 

The Red Eagle drainage was open for hiking to Red Eagle Lake, Triple Divide, and the beaver ponds. The Sperry Trail also was open from Lake McDonald to Gunsight Pass, but the area beyond the pass was closed.

Glacier officials have said that "initial evidence" suggested the fire was man-caused. Any visitors who were hiking in the area of Reynolds Creek on the Gunsight Pass Trail or that may have been staying in or hiking through the Reynolds Creek Backcountry Campground between July 14 and July 21 were being asked to call 888-653-0009 or email [email protected] to discuss the fire.
