 An effort to bulldoze a wide fire break and set backfires to try to starve the fires of combustibles almost led to disaster when an unexpected change in wind direction brought the fires to within a hundred yards of parts of the town, forcing evacuations on September 6.The other major fire located in the northern section of the park was the Hellroaring fire.Started in Gallatin National Forest on August 15 from embers from an unattended campfire, the fire initially moved north, but then turned around a few days later and moved south, threatening the area near Tower Junction.
