CROUCH, Idaho (KTVB) - A wildfire burning in the Boise National Forest is proving to be tricky for firefighters. The 10-acre West Scriver Fire is the largest of six new wildfires, sparked by lightning Monday evening. Fire managers say the fire is located in steep terrain, which is difficult to access.

Crews spent Tuesday cutting a path through the forest to dig a trench and get a line around the fire. Despite hot and dry conditions, Seesholtz says the smaller fires are making the work manageable. Because the fire is challenging firefighters, more resources were called in Tuesday. Meanwhile, the other fires continue to burn, but are quickly diminishing.

The Koppes Fire, 5 miles northeast of Crouch, is now estimated at two acres. The fire has a hand line around the entire perimeter of the fire. Crews are working on mopping up interior of the fire and holding the line they built.

20 firefighters and two helicopters are attacking the Bridge Fire, near Silver Creek Lookout. So far, crews have built a line around 70-percent of the fire.

The Ucon Fire, also near Silver Creek Lookout, remains at one acre in size with a hand line around it. Crews are working on mopping up interior of the fire and holding the line.

The Peace Fire is completely lined and remains at a quarter of an acre in size.

The Wolf Fire, now at four acres, is located eight miles east of Jackson Peak and about one mile west of the Sawtooth Wilderness. Eight smoke jumpers parachuted to the fire, which is located in very remote and rugged terrain.
