BOISE COUNTY -- The Pine Creek Fire burning northwest of Lucky Peak is now estimated to be around 1,500 acres, with only 10 percent contained.
The fire sparked on Monday, July 15 around 3 p.m., and is burning in Boise National Forest near Pine Creek and Grimes Creek roads. Officials believe it was human-caused, though no further details have been given yet.
There have been no evacuations, and no buildings considered threatened by the fire so far.
Firefighters worked throughout Tuesday night cutting down and burning out dry plants and brush to help protect homes and other buildings.
On Wednesday, a regional team of firefighters arrived to take control of the situation. The Great Basin Type 2 Regional Incident Management Team is being managed by Incident Commander John Kidd.
That means more expertise in fighting the growing fire, according to Emily Callihan with the Idaho Department of Lands.
"Because of their presence, it creates a higher priority for the fire in terms of access to personnel and resources that may be needed," Callihan told KTVB.
Officials kept people off nearby roads, including Grimes Creek Road, during Tuesday's burnout, and those roads have now reopened. However, officials caution they could be closed at any time due to impending fire danger.
Fire crews are currently standing by with 9 structure protection engines to help keep the fire away from the Clear Creek Subdivision and other homes in the area.
The Boise County Sheriff and deputies stayed through Tuesday afternoon to help fire crews that have been on scene since the fire started Monday.
"Today, we're back. Fire crews are staging on some houses that are not considered threatened at this time but are in the effected area," Boise County Sheriff Ben Roeber said.
Throughout the day, firefighting hotshot crews also headed up into the forest, and once enough smoke lifted by early afternoon, several planes and a helicopter also worked the flames.
Officials with the Boise National Forest say they're expecting around 240 firefighters to staff the fire on Wednesday. That includes the specialized, Type 2 Incident Management Team.
Four helicopters making water drops are also expected.
The team is expected to build a fire line around the fire's eastern, southern, and western flanks on Wednesday. Firefighters also plan to build a smaller hand line around the northern edge of the fire.
Because of sometimes heavy smoke, the Department of Lands is asking anyone driving on Highway 21 in the area of the fire to be careful because of low visibility.
