Two fires on the Bridger-Teton National Forest continued to grow yesterday — although one more signaficantly than the other. Less burning activity on the Fontenelle Fire enabled the firefighters to establish line round 16% of the nearly 90-square-mile fire. Fire Information Officer Jason Curry says there are now 842 people staffing the fire. Curry says crews will be focusing today on securing line around the flanks of the fire coming up from the south end of the fire while at the same time looking for opportunities to engage the fire on its north end and stop it progress wherever possible. Curry says there a couple of homes that are again in the path of the fire, and like the homes in the Middle Piney Summer Home Area, crews are employing some aggressive tactics to assure these remain unscathed as well. Further to the north, the Bear Cub Fire, discovered Tuesday afternoon, has expanded to 4,700 acres now but still remains well within the Teton Wilderness and away from public use areas and structures. Crews are constructing fire lines along the southwest and western flanks of the fire to contain it there while a large natural cliff barrier blocks its progress to the east. Currently there are 50 people working the fire.
