 Rick Carhart is the public information officer for the Butte County Fire Department. This fire is not out by any stretch of the imagination. There's not a lot of fire activity to be seen. There's not a lot of smoke in the air. There's not a lot of active flames, but there is still potential. Going into this weekend, he says the biggest challenge for firefighters is the extreme heat.
