Things are going well for the firefighters taking on the Observation Point Fire south of Hamilton, but because of the spotty terrain, the fire could burn until fall.

The fire grew just 12 acres while containment of the fire jumped to 30 percent yesterday. The Ravalli County Sheriff’s office even rescinded its evacuation warning for homes between Hwy 93 and Gold Creek. According to Fire Information Officer Ann Rys-Sikora, the Type One incident management team is hoping to leave the fire on Monday, but needs to accomplish some things first.

"We're going to do the best we can to knock this down, get it corralled, get a nice wide break all the way around the perimeter," Rys-Sikora. We're probably going to leave a lot of the hose lay, were leaving it in case we have to go back there and get crews to put water on it later. We're trying to set the forest up for success."

Rys-Sikora says rain will play a big role in how fast the fire is stopped, it could help or hurt the operation.

"The incident meteorologist indicated that he's anticipating a half-inch of rain, which is pretty soggy. That means we've got socked in water dogs, it means that aircraft cannot fly... it's beneficial in on a lot of levels, but it deters operations on a lot of levels too."

The goal is to have four hundred feet of dead space between the fire and the surrounding area before the Type One crew leaves, even once that is achieved though, some sources say the fire could burn as late as October.
