Fire rekindled early this morning at the Underwood Fruit facility on the west end of Bingen, sending flames back into the air.  That did not come as a surprise to fire officials, who had said late Wednesday afternoon that they expected the fire to flare up and burn additional material and release heavy smoke.  The fire is contained to one building but is in the rafters, making it difficult to put out.  The fire was reported at 5:45 a.m. Wednesday.  The company employs about 270 workers at the site.  According to its website, Underwood Fruit and Warehouse packs and ships for 55 area growers.  The company was formed in 1917 by seven local growers.  Eleven Klickitat County fire departments, a Burlington Northern Santa Fe fire train, Hood River Fire Department, Skamania Fire Department, and Mid-Columbia Fire & Rescue have been involved in the firefighting effort.
