An interagency management team says the Bertschi Road Fire is south of Glenwood is 80% contained.  Hand held infra-red devices used to detect heat continue to be utilized within the perimeter of the fire footprint.  Today crews were focusing on mopping up any areas of remaining heat near the edge of the fire.  In some areas around the perimeter, up to 300 feet of mop up has been achieved.  The Temporary Flight Restriction over the fire has been lifted.  The fire started last Thursday and its cause remains under investigation.  On Tuesday researchers from the University of Washington in Partnership with the Vulcan Group, a company founded by former Microsoft co-founder Paul Allen, arrived at the fire camp.  Their mission is to learn about the different challenges wildland firefighters face on the fire lines in order to find solutions using new technologies.
