JACKSON, Wyo. — The Lone Star Fire in Yellowstone is holding at about 3,346 acres. Cooler, wetter weather has allowed firefighters to concentrate on point protection at Old Faithful and cleanup operations.

Authorities caution the fire is still active and with warmer, drier weather forecasted for the coming weeks, along with hard frosts at night that have killed light vegetation, fire activity is expected to increase as these fuels dry out.

Firefighters are continuing to cut trees and heavy vegetation around the Old Faithful area to protect power lines, historic buildings, and communication equipment. These efforts will help protect the Old Faithful area if this, or any other wildfires, threaten it in the future.

The fire continues to burn actively in unburned sections of the forest in spruce, fir, and lodgepole pine. Active crowning, long-range spotting has been observed. The fire is three miles south of the Old Faithful and one mile from a backcountry cabin.

Joe Rock, of the West Yellowstone Smoke Jumpers, is still in command on the fire. He has 52 personnel at his disposal. Containment is estimated at October 30.
