The lightning-caused Observation Fire, above the Lost Horse Observation Point, has grown to over 25 acres in steep, rugged terrain. The fire is 10 miles southwest of Hamilton.

According to Bitterroot National Forest's Marilyn Wildey, three helicopters are making water drops and two 20-person hotshot crews have joined the initial 8-person team that responded to the fire Friday afternoon, June 24.

Three engines are also on the scene. Windy conditions are causing erratic fire behavior. The road to the Lost Horse Observation Point is now closed above the junction to the Camas Lake Trailhead. The Camas Lake Trail was still open Saturday.

Wildey, in a press release said the fire danger is climbing in the forest and the "high" rating may happen this next week.
