Fire officials say winds were steady at 15-20 mph throughout the day, with gusts of 35 mph, making it difficult for crews to make gains. About 100 people are assigned to the Bear Gulch fire, with a specialized "type 2" incident management team taking command of operations late Tuesday afternoon.

Because of the fire, the North Fork of Deep Creek Road and Cabin Gulch Road have been shut down until further notice. Fire information officer Liz Van Genderen says no structures are being threatened by the blaze. The fire was first reported shortly before 2 p.m. Monday and is burning in heavy timber.
