A fire has been burning for about a week west of highway 75 between Hailey and Ketchum. It has covered 65,000 acres, is moving to the north and east and is now the number 1 fire priority in the country.
Evacuation has taken place on most of the mid-valley area to the west of the highway and some of the area to the east. Areas to the north, including the cities of Ketchum and Sun Valley are now in pre-evacuation warning.
Bald Mountain is somewhat protected by previously burned areas on three sides from a fire in 2007.
I live just to the south of Hailey, so am not affected except by smoke, which has been pretty bad at times.
