The U.S. Forest service said Sunday the fire is about 25 percent contained.
State officials issued a health advisory for portions of eastern La Plata County because of smoke being generated by the fire, which is burning in the San Juan National Forest.
Firefighters were also called out for a fire that burned in thick vegetation at the base of Sleeping Giant Mountain near Steamboat Springs on Sunday.
Authorities said that fire started out as an agricultural burn and has scorched about 40 acres.
