Firefighters have been performing new fire prevention tactics on the Reynolds Creek Fire in Glacier National Park in an effort to strengthen fire lines with new "burnout operations."

The Associated Press said fire crews have containment lines around 63 percent of the fire that has burned four miles west of the St. Mary Visitor Center. On Thursday, winds caused some fire spotting, but with anticipated weekend-high temps, wind and low humidity, the conditions could lead to more flare-ups.

The July 21 fire has led to the closure of an 18-mile section of the scenic Going-to-the-Sun Road. GNP officials reported earlier this week that the west side of the park is still open for recreation, however.

NBC Montana visited the site in the park on Friday and reported that the fire is spotty, and certain areas feature steep terrain that poses too great a threat to fire crews.

"To date we’ve had zero injuries on this incident, Operations Section Chief Reggie Day said. "And with the steepness of the ground (and) the distance of travel, that’s a huge, huge accomplishment. (Firefighters) are really being cognizant of what they’re doing, where they’re at and how they’re doing."

The Associated Press said fire officials gave media members a tour through the still-closed fire area on Thursday, "noting improved views of St. Mary Lake through the burn area."

The report said crews expect the area will continue to burn until it snows.
