The fire started last week following a lightning strike in a wilderness area just west of the state highway. The area has lots of dead and downed trees that were killed in a 2000 wildfire. The fire grew significantly Thursday because of high winds and has consumed nearly three square miles. Fire crews kept it from jumping the highway.

The National Forest Service says it will decide Friday morning whether it is safe to reopen the highway.
